Oil Jet - Difficulty Finding Neutral

[theknurl]

out for a stator test ride;
with a new clutch oil jet Aprilia part #0268751 size 40 and a new seal in the slave [i found replacement seals at the rebuilder [because brembo does not sell kits]
the seal is marked "25 DJF 3505817 1 1/8 H" it is a standard 1 1/8 th inch master cylinder seal
seal dimentions;od 29.5mm, id 18.5 [tapered] and 4.4mm wide]
AF1 has slave seals too
'04 &'05 come with a #60 jet, '06 and later with the #40

there have been later bikes reported with the larger #60 jet so you might want to check

the jet was $8 the seal $3 best money spent on the bike yet
no creep, no drag and neutral without thinking, wish i'd done this 30,000 miles ago

congrats on the easy fix:worship:
well it did take a while to hone the hard annodize out of the slave cylinder to smooth it, [the rough surface/return spring is where i think the air comes in as the vacuum drops] but now i have a real clutch. i recommend this mod to everyone
i only bled my clutch once in 29,000 miles, but the change is like night and day.... little wiggle of the toe and you're in neutral.

Hi Noel, where is this jet? sounds like a great fix.

[tdogg]

It located right above the clutch slave. The jet is rather difficult to get out with out some very small tweezers or something but it is really easy to to get to. Just pull lthe cover bolt out and the jet is behind it.

Thanks tdogg, I have been thinking about a new slave, mines not really ever had a problem, but it is quite heavy, and I'm changing gear alot in the tight twisty roads over the mountains. Maybe MPL or Evo' ??

Changing gear using the clutch??? I'd be interested to find out how that works out for you, as mines quite heavy.

[StefanJ]

I'll be trying this. I just want to make sure I pull the correct bolt off.
Any pictures from the side?

Thanks

[twowheelblonde]

Noel - so just to clarify, are you recommending this as a fix for the annoying air leak problem? (lucky you don't have it) or is it just a friendlier performing clutch that eliminates those other annoying issues.

Here's a shot from the side. I hope you can see the red arrow.

Remove that bolt and the jet is underneath. You don't have to drain the oil, but a few tablespoons will drain out anyways. Use as big a screwdriver as you can get into the slot of the jet since you don't want to damage the soft brass when un-threading it. Grab the old one with tweezers or something and take it out.

Install the new one and only make it as tight as needed to keep it from un-screwing itself. It's not like the jet is holding anything together, so almost no torque is required. Install the bolt again and torque it to 100 in-lbs. Go ride and make sure it doesn't leak!

Please keep in mind that a badly-bled clutch master and/or slave cylinder will cause the same problems, so check that first since it doesn't cost anything.

[burnham]

The oil jet won't do anything for the air leak.

[StefanJ]

Awsome!!!!
Thanks so much!!!!

[fast4d]

I did the oil jet couple weeks ago. that and a good bleeding fixed my neutral problem. I used a really thin drill bit to get the old jet out.

Drive through Ojai much?
I can't wait to try it out! I just need to take some time to do it. Most of my time is being spent with family when I am not on mission which seems to be quite frequent these days.

yes but I usually ride my motard up the 33.

if it's late the 150 gets jammed with cars then it might be better to take the 101 and up 33.

it might be a bit wet (and possibly snowy) and dirty this weekend.

[StefanJ]

I grew up there. My grandmother still lives there.
Every once in a blue moon I might visit (very blue). I think the last time I was in Ojai was about 3 years ago.

Hello.........Is there an online shop to buy the seals? I have 3-4 people (inc me) with 04 factorys, that need new seals........have been bored of clutch bleeding

AF-1 has Brembo slave seals. i used the automotive brake M/C seals because the rubber was harder, which gives slightly more piston travel
make sure the bore of the slave is smooth... mine was bead blasted!!

Noel,

Excellent thread!

The 1998 - 2000 (US 2001) engines came with a #75 oil jet... cool!

[fast4d]

Noel,

Excellent thread!

Will the #40 jet upgrade also work on the 1998 - 2000 engines?

yes. I have it in my 01

[ressveeeare]

It wont make the clutch slip more then as a result?

[theknurl]

No, it allows the plates to separate cleanly, so you can get it into neutral easier.....and the plates would slip less with less oil, because there is less oil for the springs to squeeze out.

[ckruzel]

hey knurl, the best clutch action my bike had was when i had the wrong billet clutch master, it was the 18x19, the clutch action was awsome, little stiff but i liked it, engaged firmly, that was until it pushed the last clutch plate off the shaft - DOH!

[theknurl]

Chris;
i only use the clutch for launch and going into neutral [sometimes]
the mod was the best $11 i've spent on the bike!

Noel-theknurl

[Stick]

Changed the jet...did everything as directed and now have a slow, small....very small drip coming from the jet cover bolt! Would it hurt to use a small bit of thread seal of some type? Loctite?

[theknurl]

stickmeister;
i'd remove the cover bolt clean it and the mating surface and put it back in

Noel-theknurl

[kzmille]

Get a new crush gasket.

[fast4d]

I did the jet on my 2004. made a big difference. Neutral is still a little hard to find when cold but OK if I'm still rolling. it's in the mid 50F. I think eventually I'll have to get a brembo forged clutch master for a cure all.

[theknurl]

i'd like to try a #30 or even a #20

Noel-theknurl

[Stick]

clean it...gasket....got it. will do thanks! if it still drips....duct tape and caulk!

[bomfunk]

guys, just tried this method. replaced the jet and didn't do anything else. works like a charm. man, do i like to be able to find neutral :cheers:
thanks a lot. :plus:

[kzmille]

...The #40 jet (that you just installed) has a larger hole than the #60 that the engine came with. Since more oil is being allowed onto the clutch pack it will lubricate the plates more and erase some little problems (like not being able to find neutral and having the bike creep forward while in gear with the clutch in)...

sjruckle,

This information about jet sizes and numbers is wrong and should have been challenged. On these oil jets, like carburetor jets, the higher the number the larger the hole, the lower the number the smaller the hole.

[amauri]

sjruckle,

Correct.

The original intent of the smaller main shaft oil jet was to supply more oil pressure to the crankshaft.
As a result, neutral became a little easier to find.

[Peter S]

I just put the #40 jet in the Falco and the RSV and it has made finding neutral much easier in both. I have also noticed, on the RSV in particular, that gear changes have become smoother right through all gears. Well worth the trouble.

[theknurl]

the oil jets are marked as to the diameter in 100ths of a millimeter

carb jets are marked by cross-sectional area
ever see the square in a square stamped on Mikuni or Keihin jets?

Noel-theknurl

[Roadless]

So the OEM oil jet is 0.6mm in diameter, and the replacement is 0.4mm in diameter ( across the hole )

Where would I find one commercially ?
( without having to buy it abroad and ship it home )

[amauri]

take yours off, measure the threads and diameter and Google

[kzmille]

...Where would I find one commercially ?
( without having to buy it abroad and ship it home )

Any aprilia dealer can get it for you. Part no. for the #40 jet is 0268751.

[Roadless]

KZ...you might read the location ...I live in an island of 300 thousand.....there is ONE aprilia dealer, and he does the same thing as me, the question was, are there jets that fit but from other sources, like for gas, or water or carb-jets that would fit the bill, and allow me to shop locally, yes, locally....for the part.

[kzmille]

...the question was, are there jets that fit but from other sources, like for gas, or water or carb-jets that would fit the bill, and allow me to shop locally, yes, locally....for the part.

The short answer is no. See post no. 36 above.

[theknurl]

hey folks listen to what Roadless said, he can't get things easily, period

AF1 provides us with great access to parts and for US stateside postage is cheap

the list for the jet was $10.20 in July '07 [not what i paid though]
now the international shipping rate starts at $40 so now it's $50....now if Roadless has a VAT[valve added tax] and or a luxury tax....
[France's luxury tax used to be 45%]....add a VAT to that holy shit a $0.50
part can be $100.....!!!

yes i used to buy Mikuni main jets from Sudco for $0.45

yes i measured the thread, M4x0.7 and Googled it ....no luck

so this week i'll go to Sudco...a Keihin air bleed looks good but they list the length of the jets not the thread, maybe Roadless will get lucky.....i get bulk dealer price, if they have it, i'll buy it and just send it to him
yes i'll take a calculator and some wire drills to measure jets

just trying to help forum members out

Noel-theknurl

[amauri]

the question was, are there jets that fit but from other sources, like for gas, or water or carb-jets that would fit the bill, and allow me to shop locally, yes, locally....for the part.

If you don't want to have AF1 send you one via Post, it is up to you to get resourceful.

In your shoes, I would take it off and check with the small engine shops that work on lawn mowers and trimmers. They have small carburetors.

I've also used solder to fill the hole on a carburetor jet and re-drill it to desired size.
Now I’m not saying this is the best fix but in a pinch, it works.
What's the worse that could happen, hot oil melting the solder?
Doubt it, but no harm if it does.

So in summary, no one knows of another part that is a direct fit.
But, since it's only function is to restrict oil flow, there's not much to it.

As long as you don't strip out the threads or block the passage way completely.

[PlatinumRSV]

Thanks for the great info guys!

I just bought a 2001 RSV1000 (with 8,000 miles) this week and am having the first gear creeping and hard to find neutral issues. I will check with my dealer on Monday to see if they can get the part...

[amauri]

The oil jet will not fix for your “creeping” issues.

Your clutch needs bleeding or adjusting, how much lever free play do you have?

[PlatinumRSV]

Thanks for the reply. I just got the bike this week and haven't really noticed the amount of play but will take note on my next ride. The most frustrating thing is not being able to find neutral when stopped at a light...

[amauri]

Forgot to say welcome to the forum and the Aprilia experience.

As with any new used bike, check everything out and learn how the bike likes to be treated.
Lots of info here, just don't take all of it as absolute fact.

[....]

incorrect.

correct.


'04 &'05 come with a #60 jet, '06 and later with the #40 Noel-theknurl

Noel, I'm not sure where you got this information, but after checking my bike (07.5) I found that the #60 jet was used, and not the #40. I ordered the 40 from Af1, and installed it.

Now here is why I did this:

I didn't have any issues with the bike creeping unless there was a shit-load of air in the lines/master. And even then, I only had that issue happen to me once (pre-slave install). I've since installed the MPL slave (from matrixmotosports.com) and hadn't had any significant issues with the lines since. In fact, bleeding is a rare necessity nowadays. That said, I still would have a slight bit of trouble finding neutral from first gear, however could always find N from banging it down from second.

After installing the #40 jet, I can find N from either 1st, or 2nd gear. I'm posting this for anyone who has an 06+ bike, who read this thread, and deduced to not install the #40 jet based on earlier posts that advised that the 06+ bikes already had the jet installed. Mine is a 07.5 and did NOT have the #40 jet installed. It had the #60. I know this, because once the old one was out, I compared the two and seen the differences with my own fuckin' eyes.

Ever since I've installed the Jet, as per Knurls advice, finding N is cake. I really hope this post helps some of you guys. I imagine some of you with 06+ bikes disregarded the new jet based on the misinformation on this thread. My bike did have the 60 in it, and changing it to the 40 jet has made a significant difference in finding N.

[shelbyguy]

Thx Normous! I went back and posted in that thread. Read it. Keep in mind, I never made mention that my bike crept fwd. I installed it for a different reason.

...at any rate, I'm very curious what Noel, KZ, and Uri have to say about this. I wonder how many fuckin' people disregarded changing the jet out because of Noels' misinformation.

this info was stated in the shop manual also...so basically aprilia also misinformed every and all dealers that are supplied with this shop manual?

[....]

Incredible.

Explain to me how a #60 got on my bike.

[....]

Again, explain to me, how the 60 jet got on my bike.
In fact, anyone explain to me how the 60 got on my bike.

[theknurl]

don't remember who posted that '06 and later have the #40

but i guarantee you, i didn't figure any of this out!!!

i'm sorry if anyone feels mislead......i took the suggestion and it worked, posted it 10-22-07

as to how your's had a #60 in it? ......they ran out of #40s??? ...got me

just used search and the Falco guys were doing the change in May '07

That's fine Noel. Your idea of going to the smaller jet did indeed work for my bike. I'm guessing my bike (being the 07.5) isn't the only 06'+ model bike that has/and in my case, had the 60 jet installed. Your advice is golden. My only beef was that being said the 06+ bikes already had the 40, was untrue. As in my case, it didn't. I had the 60.

How in the hell did #75 jet get used on the Falco's? :o

Was my bike, and all of the Falco's out there put together on Billy's birthday party at the factory, on a friday afternoon? Gah!

[theknurl]

it wasn't Billy's birthday party......silly
it was Wilhelm's.....its Austria.....and yes, they were pounding the kirschwasser

Noel-theknurl

I see what you're saying now. I retract that part of my post then. You were instrumental in bringing the idea back to light on our side of the mountains however. And that, I appreciate. N can now be found very easily from either 1st, or 2nd.

I'm never on the Falco forums, so I would've NEVER come into this idea without your help. And for that, I'm grateful. Thank you Noel. Thank you very much indeed.

As for Shelbyguys post above, might I add...Even factory manuals can be dead wrong. Yes, they can be. To believe otherwise, is ludicrous, and lemmingish. You're not a lemming Norm, so stop acting like one.

[theknurl]

somebody posted about the later '06+ bikes using the #40.....
think it was Amauri that said it.....so i tried it, and it worked

search put me on the Falco page, never been there before
hey, i didn't even know the oil jet existed until that post.....but it makes perfect sense, less oil....less drag on the plates

all i did was try it and post that it worked, somebody else deserves the credit

Thank you Kirk. And with that, I still stand by my statement, in that in the case of my 07.5 RSVR, it did in fact have the 60 jet installed. Not the 40. Here is a picture:

http://i469.photobucket.com/albums/rr60/foto1k/clutch/Clutch011.jpg

Furthermore, I'm confident the jet that was shipped to me was the correct size, as this particular package was packed, and transacted by Steve @af1 himself. I had communication with him prior to my purchase of two jets. Just because some printed material says one thing, doesn't mean it's gospel.

[Cajun]

interesting means my 06 might have a 60 jet so might find a 40 jet to see if that help with my clutch also

According to Shelbyguy, there will be a stamp on the side of your jet. It'll either be stamped with a 40, or 60. Now I don't remember seeing anything stamped on the side or anywhere on the jet, but then again, I never really looked for it. The jet is at home, so I'll have to check back and report later.

AND BE SURE to check your size jet first before ordering it. Shelbyguy advised after checking his, he does indeed have the 40 in his already in there. And as we know, I didn't. So be sure to check yours before ordering.

[....]

Got home, checked the old Jet that I pulled out of the 07.5 RSVR and it is confirmed to have 60 stamped on the side of the jet head.

[Cajun]

cheers .... the clutch is the final annoying factor we have with our rsvr, fixed the stand, brake, stalling now just the clutch

was gonna head down the route of replacing the m/c with something of a gsxr/r1 to see if that would help.

Cajun,

I lie not when I say it takes 5 minutes to unbolt the containing bolt, and then unscrew the jet. Clean the jet off with a rag, and hold it to a light. You'll see if it's a 60, or a 40. Shelbyguy said his was a 40, mine is confirmed a 60 (switched to a 40) and he and I both have the same year model bike.

Has nothing to do with the Slave. However, that said, having the new slave is a must have. In order to know, you just have to use it to believe it.

I wished you would have checked yours before buying it. You very well may have already had it installed.

Actually, you should be good then. I doubt you've got the 40 in there already unless the previous owner already did it for you. If you end up already having it installed, I'm sure af1 would take it back, minus shipping charges. Or, you could sell it to someone on the forum.

[mad modder]

yeah i'm not worried, if it was like a 300 dollar part then i woulda checked but whatever never hurts to have extra small stuff.

it always fun learning a whole new bike. coming from a jap inline to a italian twin is a new experience for me, i had twins before but japanese. learning all the little quirks is always fun about a bike. at least for me, good or bad.

yip. my feelings are the same. :)

[fulcrum]

I did this quick mod this weekend and I am noticing a slight improvement when I use my entire hand (all fingers) to squeeze the clutch.
However, I normally use only two finger and in that case, finding neutral is just as tricky. I guess, I have som bleeding and/or adjustments to make.

is there only one option for a aftermarket clutch slave?

And...how's it workin' for ya? Better I hope.

Now order the slave, and you'll really be cookin'. MPL is what I've got. Thanks for reporting back. :cheers:

[mad modder]

lol, i have no idea, i just dropped her in and put on my brembo MC, but i don't want to bleed the clutch just to do it again in a week or so when i get my slave and slipper in. so its just sitting there. its a track bike anyways so we'll find out next month

Maddy,

Where'd you get your slave from? And which one? Hope you went with MPL?

[mad modder]

haven't ordered one yet, i was planning on a matrix. should order it here in the next few days. my next track day isn't for like 2 1/2 weeks so i'm good.

Modder. Get it ASAP. Cuz as this price, they're going fast! Do your research and you'll find a lot of posts about people not being happy with the EVO slave. That said, I haven't had any issues with my MPL.

Get it while matrix still has them. I see they sold out of some other colors already.

[fast4d]

I'm tempted to put my non-radial M/C (from 2001 RSVR) on my 2004 so I don't have to bleed it so often.

[kzmille]

Even if you did not leave it that way permanently it might be very instructive for many.

[mad modder]

just finally bled my clutch with my brembo MC and that .04, SO much better. finding neutral is SO much easier and the shifts are so much cleaner. i can't wait for the billet clutch slave and Slipper.

[Johnnycab]

has any one figured out what the hole size is. I could just resize it but don't know how big. I know I already have this bit at home. WHAT is the decimal size of both units. I haven't pulled mine out ot check it yet but both bikes are an early 04 vin 172 & 190.

Or does it need to be a smaller hole.

[....]

Or does it need to be a smaller hole.

Your answer is on page 5.

[theknurl]

the 40 is 0.40mm and the 60 is 0.60mm pretty tricky no?

you could solder the hole up and redrill it but then you'd need to chamfer it too

buy the jet!

Noel-theknurl

[Johnnycab]

yes, actually it's brass so it would be Braze it. then redo the hole it would take me 10 min at work (free) and yes i'd clean the hole up. Thanks again for the simple reply.

[theknurl]

Johnnycab;
don't try brazing it, the rod and the jet, melt at about the same temperature.
you can silver solder it, depending on the melt temp. of the silver solder
for $8 i wouldn't mess with it......and i didn't, i just bought one, and i've been welding for 55 years or so!

Noel is the motherfuckeeng man! :worship: Just rode today thinking "damn, it's so much easier to find N since I did the swap. That Noel guy is allllll-right!" :cheers:

Glad it worked out for you! Have you changed your slave? You can get away with the stock slave, but changing that out will REALLY spoil ya.

I haven't changed the slave yet. I've been doing a lot of research here because my clutch needs to be bled just about every 100 miles. Seems like it has worked for some, but not all. I need to find a definite answer before I spend the money.

The new slave I don't think will help with the bleeding issues, but changing out the master most likely will.

[ckruzel]

i never bled mine again after changing the master, (few years and thousands of miles) the clutch fluid doesnt darken anymore either like when i used the original. neutral very easy to find, never did anything with a jet or anything like that

[prillerman]

Anyone have step by step instructions (with pictures) on how to do this? I've never taken my bike apart at all, but finding neutral on my bike is like finding a needle in a haystack.:eek:

My bad - I saw on page 5. Anyone know where I can buy a brembo MC?

Just did the change to #40 jet on my Falco this morning, was a very old #75 in there from stock (she is an old bird).
I am a complete tool when it comes to spannering, I read-up for about 2 weeks before so I am sure I know what I am doing then in the deep end, but thanks to all the various posts, pics & experience on here has worked a treat, dead easy.
Just get the #40 jet & make sure you have the correct size screwdriver to fit it & that the screwdriver don't have wide sholders at the end otherwise it wont fit down the hole once you take the outside bolt out.
ApriliaJoel, get the bits & do it, is simple even for someone like me.
Mark with permanent pen the shift location on the spindle before you take it off, then remove the black plastic cover over the front sprocket, see the alen bolt above the oil filter cover, wip it out, see bit of fluid leak, cloth, screwdriver in, old jet out, new jet in reverse previous & bleed.
Even for me going back & forward to read through threads took only about 45-50 mins.
Go do it, is like bliss changing gear now & finding N is easy.
Thanks Org:worship:

Unfortunately I don't know know what "shift location on the spindle before you take it off, then remove the black plastic cover over the front sprocket" means/are - and I can't seem to find the $20 MC everyone refers to.

Also... I have no idea how to bleed the clutch lines :o

Bleed form the slave first, them from the master itself. I found it helpful to gently tap the master before cracking the bleeder, it helps to move the air around. If you do a complete flush you should get a bubble or two from the master.

[StefanJ]

Just a question?
Why would you bleed from the slave first? The air should be trapped up high by the master and bleeding from the slave first could possibly force the air down there couldn't it?

[StefanJ]

Has a different slave cylinder helped any?
I am thinking of mods for when I return from Iraq and the clutch is for me a pain in the rear that shouldn't exist!

[popik]

I have replaced both the slave with the EVO and the master with the Brembo billet as well as the oil jet and the symptom is 95% gone. I still find i need to bleed the clutch every couple months but i like it that way...gives me an excuse to pull some wrenches on her

I bleed the master first as well. sometime I find that bleeding the master is good enough.

[HARDCHARGER]

Just the way I've done it with success.
Suck out the old fluid in the master, fill it, bleed the fresh fluid through the slave, bleed the master.

Where can you buy these? I haven't found a place to buy the Brembo.

I have a Brembo RCS Master that i will install when I return from Iraq. I'm wondering if the Evo will help since I have heard mixed things??

I like the idea of fresh fluid!

[HARDCHARGER]

The Evo slave didn't work with the Brembo master ( For Me anyway)
I installed the stocker back.

I saw an immediate change with the new jet

Does it take awhile for the oil to circulate and the new jet show effectiveness? I installed the #40, and went for a short 5 min ride, and there seemed to only be a slight difference...

[catch2otwo]

Does this work with the Tuono as well? I know there are a lot of similarities between bikes but lots of differences

[theknurl]

same motor!

Whats what I thought, figured I'd ask though. thanks

[jlburgess]

Does this mod work on earlier models too? Mine is a 2000. Ever since I put a Barnett in, neutral is nearly impossible to get when your stopped. It improved slightly when I put the stock springs back in.

I also don't feel the pulsing of the vacuum slipper like I did when I test rode a new one long ago. I seem to have some vacuum at the hose, and the diaphragm passed a suction test.

[theknurl]

1st welcome to the forum

i don't know about the 1st gen clutch....
early 2nd gen had #60 oil jets leading to too much oil on the plates; ie increasing drag

make sure your plates and discs are smooth and flat
a bent or warped plate, or discs with too much 'fuzz' on them will cause drag too

[jlburgess]

I spent the last 3 months working with my new Barnett clutch. It dragged bad making shifting notchy and was impossible to get into neutral from a stop. It worked fine before with the oem clutch. I bought the bike used and the clutch wore out 1500 miles later.

It was the friggin' oil jet! I changed it from a 75 to a 40 and it's cured. Thanks for the advice!

I found the jet is a bitch to get out and only a needle can get behind it. I got it out with a wet/dry vac by reducing the end to the size of a vacuum tube. You could hear it get sucked in and then removed it from the filter. That tip will save someome an hour of frustration.

[Oberon]

Hello

I just want to add a photo, where you can see the stamp on the oil jet.

This one is taken of the original oil jet from my 2004 Factory.

It's a #60 which is clearly visible.

Regards
René

[EditTim]

Just ordered up two for both my bikes. I couldn't get them out w/o drilling them out with a reverse thread bit, thereby destroying them, even just to check to see what was in the T.

#60 was in the Futura (04)
#40 was in the T Factory (07.5)

Now both have new #40's.

Fast, easy job with the reverse bit.

I've got the Fut apart right now (forks/exhaust), so won't be able to test anytime soon...

[2slow]

I replaced mine with the #40. I wasnt sure what I had in there because im the second owner but changed it anyways. For some reason it still feels the same. I need to down shift to 1st make full stop then shift up to second then down to neutral. I hope AF1 sent me the right one. The part# looks right tho
