4ROAD exhaust

[cmsdms]

Someone mentioned that a company called LEOVINCE makes an exhaust for our scoot. He's right. I looked into it and it is supposed to increase performance. I got a price of $361 from Indigo sports in Georgia. If you go to LEoVinces website they have a photo. Its all stainless. My wife says she would like a little more sound. I wonder if this would do the trick? Any opinions?

My 10 year old Mac won't quite get me to the site to see the muffler. I can get to one click before the picture, it's:

That is friggin awesome....Im getting one.

[cmsdms]

Hey Micah. I am thinking about getting one too. I wonder though if the bike will be louder. I am hoping it would be. What do you think? If you need the phone # for ordering i can give it to you. Regards Craig

[sammyboy78]

I am very interested in getting one... I would imagine someone is already having one shipped to their homes within the next week or so. Can you tell us how much louder it sounds?? Also does it affect the emissions standards? Finally...someone should test the acceleration before and after installing the muffler. Thanks a lot

Come on,Guys,we do not need more Noise.Leave that to the Simpletons on their Harleys.We do not need to alianate
the Public any more than those Guys already have.There are Plans to keep them out of Daytona,specifically because of the horrendeous Racket being created,during the Meet.
Enjoy your Ride

[cmsdms]

Hey Roller. The reason I want the bike a little louder is not to disturb the peace but to make sure people in cars can hear you when they cannot see you like in the blind spot of a side mirror. Before I put pipes on my Yamaha People had pulled into the left lane (while I was there). With the increased noise level that has not happened. I am not looking for glass rattling just something up a few db. You are right about being too loud though. That is not a good thing. I do not believe this muffler does that and the reason I think that way is becasue when you look up this muffler there is a pdf file showing that it was approved as a legal replacement for the stock unit. They have noise restrictions over there too. Regards

[timbo]

In Europe anyway, the 4Road exhaust comes with a baffle plate at the back, secured by two allen keys I believe. With the baffle, it meets European noise regulations, without it it makes more power and noise. I saw a dyno test on a Suzuki Burgman 400 and it made quite a lot more power without the baffle plate, though barely as much as with the standard exhaust with the plate in. I've no idea how US noise regs compared to European ones.

[Clocky]

Just spoke to Infinity Motorcycles in the UK and they are £229.99 inc. VAT over here.

I'm tempted... but I think I'll get the "Lip" first as my next investment.

[LCoop]

I've ordered one of these for my Honda Reflex - $380 delivered to the door - ouch! I'm just biased for stainless steel - put some stainless steel mufflers on an old R60/2 BMW years ago - now its sitting in a backyard shed needing repairs BUT THE MUFFLERS ARE BEAUTIFUL!

Anyways the 4Road exhaust is advertised as having some kind of removable baffle or something. Now I'm wondering if I'll need to adjust my carburetor air/fuel mixture - by screw or rejet - ?? - In your case I guess it might be "recomputerize" your fuel injection? Just wondering what other effects it may have on overall operations. Guess I'll find out. safe ridin' all, --LC

[Gnome]

LCOPE you hit the nail on the head with your last message. An after market muffler cuts down on back pressure and allows more gas flow. However without increasing the air flow in and re-jeting to get more fuel you don't get a major increase in power. Since the Atlantic is injected and controled by a fuel managment system you don't have a jet to re-jet. You must reprogram the brain box. My dealer tells me it is the same computer that is used on the Ducati's but needs a diffrent card to program. He did not have it the last time I checked. You could probably rework the air intake to breath better and replace the exhaust system but untill we can reprogram the fuel curve the power increase would be minimal. Then there is the statement from Aprillia that they think the CV system is pretty maxed out with the 39 HP that the engine makes. So will the transmission and belt take the increased power? I am happy with my scoot the way it is and the price seems high for a little shine and noise. But to each his (or her) own.

[LCoop]

My Honda Reflex just has a "plano" carburetor - so guess I just need to closely watch the spark plug color and condition - ??. Yeah the muffler is expensive but what else I got to spend my bachelor $$$ on? (The "chick thing" is under CAREFUL control.... - (;^)

[micah apriliaforum com]

I have ordered the pipe...it will be in the USA in 4 weeks. The baffle is removeable for those who want a little extra noise out of the exhaust side. The silencer and mid pipe are constructed in Stainless steel for max corrosion resistance.

[timbo]

Yeah - Its probably worth leaving it until the original one rusts through - I wonder how much the standard exhaust is compared to the 4Road??
I'm toying with the Lip as well, though its almost as much as the Givi......

[Clocky]

Well, I don't know quite how much the Givi is over here (£80 or so?) but I've gone ahead and ordered the "lip"; with the currency conversion and standard priority mail rather than UPS, it came to just under £58.

I honestly couldn't justify the UPS shipping being almost as much as the lip itself... I mean, $50 USD? :(

[bigbob313]

&nbsp &nbsp &nbsp &nbsp Just realized I also had a ££££
sign. Now if I only had a conversion table... I recently ordered "Twist & Go" from the U.K. Good scooter information. :rollin:

[timbo]

Interesting - I'll be interested in seeing how long it takes to get here and what you think of it.
One snag though - if you look at the web it says that you really need a temperature of 70 degrees for the adhesive to work - I don't know where you are in the UK, but here up in the North East, we only see 70 on a few days a year!

[april500dk]

You only need the temp. to be 70 degrees when you stick the tape on. After that it doesnt matter if the temp drops. I installed mine in 10 degrees celcius!! It is still there.
Ride on

[Clocky]

My "lip" turned up last week; very quick response time really. It came on the Parcelforce van and must have took about 5-6 days from ordering to my doorstep (Surrey).

Am about to install it now; just checking out the photos of the installations here, and my windscreen has a rubber edging around it which limits quite how close to the edge I can get with it for the bottom two mounts.

As for the temperature, I'm in a bit of a quandary as to what to do - it's 44F here right now - and like you say, unlikely to get much above that for a few months. I guess I may warm up the adhesive briefly with the missus' hairdryer!

I'll let you know how it goes.

[timbo]

Thats quite quick for a few 1000 mile delivery isn't it! Parcelforce can take weeks to deliver things within the UK!
Perhaps if you put a fan heater or something in the garage for a bit it'll warm up things up sufficiently...

[ScudaMax]

Clocky - I recommend removing that rubber edging from the stock windshield. It pulls of very easily by slightly spreading one of the end clips then simply unwind it. I lightly sandpapered the edge afterward to remove any rough edges. IMHO the windshield looks and works better without the beading anyway. Regarding the temperature, I took the windshield off the scoot and installed the lip in the house where it is warmer.

[april500dk]

Yes they respond very quickly. Nice. I live in Denmark and ordered mine from the States and it arrived only 5 days later.Well I payed 25 USD for the freight but still!!
I took of the rubber edge on the stock screen. It looks much more clean. It doesnt disturb the eye and then you can get closer to the edge with the mountingtape. Remember there needs to be a slot of about 15mm between the screen and the "LIP" for the air to have enougf room to accelerate and create the desired effect. Dont mount it too high on the screen. I know it is tempting but I tried that and it works better if the lip only extends the screen by 20 mm or so.
Good luck. Let me hear you results.
Ride On

The manufacturer has not provided us with any additional info, sorry.
Don't get mad at us. Visit their web site and see if you can find out more.
Thanks

[Clocky]

True to form, the lip came pinging off today on the first slightly bumpy road I had to travel on. The adhesive managed a whole three days in occasional sub-zero temperatures, but I think I'll have to concede defeat for now and install it in the house come the weekend and leave it to set in the warmth overnight. I'll probably remove the outside ribbing at the same time.

So anyway, how difficult is it to remove/replace the windscreen? Two bolts either side of the dashboard I can see; I guess there's another couple involved on the front... erm, isn't it six in total though?

Oh and lastly, my first impression of the Lip was "that's not all that great"; then I shifted it down a touch as per our Danish friend's advice above and I still thought "well, that's not too bad". Now it's come off and I'm back to being buffeted around the head again, I realise that it made a HUGE difference!

[april500dk]

Hi there. I too tried to take mine of the other day, just to feel the difference, and I was amazed. It really makes a BIG difference. Remember the tape has to cure for 24 hrs. before it reaches its final strengh. Then it stayes.
Im glad I could help..
Ride On

[timbo]

Yeah its a bit cold isn't it (and if its cold in Surrey, you can guess its really cold up North!) - though our Scandinavian friends would no doubt think its warm here! As for the Lip, I don't get too many problems with buffeting (I'm 5'10") but I find the screen noisy at speed - did your brief experience with Lip make a difference in that respect?

[bigbob313]

Two screws/bolts at outer edge of black plastic/base of W/S; and two in front near center. Remove black plastic (slightly spread "wings"); then you have access to the 6 screws holding on the W/S. There are instructions for this in the owners booklet. You need to know how to do this removal if you ever need to add coolant. There are many references to removal of the W/S throughout this forum. Most people mention being careful to NOT dislodge the rubber grommets surrounding the 6 nuts. I experienced a problem because the original installer cross-threaded one of the screws. All's OK now. :rollin:

[micah apriliaforum com]

I got a chance to see the 4ROAD pipe at the dealer show in Indy this weekend...I am very glad to have some on order, they are really nice. I will make it public when they arrive at the shop.

We have yet to get an Atlantic on the dyno. If anyone in Texas is interested the dyno time will be free and we will cut a hella good deal on the pipe just to do the testing.

[cmsdms]

Boy, I wish I lived near you. That's a good offer. I wonder what work if any will have to be done to the f.i. system with the baffle out on these exhausts. My buddie has a fuel injected bike and put new pipes on and did not have to touch a thing. It runs really well and naturally sounds better(and louder). I sure hope it is the same scenerio with the Atlantic. I would think with the dyno you will be able to tell real easy. Do you have a promise date on the pipes yet? regards Craig

[micah apriliaforum com]

Should arrive in three weeks. In general modern injected bikes are set up slightly rich from the factory for the wide open throttle position and slightly lean from idle up to about 3/4 throttle to satisfy the EPA here in America. We have a 4 gas EGA that integrates with our dyno software so we can see real time exhaust data when a scoot is on the dyno and held in a steady state. Often when tuning for peak power we lean out the factory mixture at wide open throttle even with pipes on....sometimes as much as 10-30% from factory settings. To make a long story short, I doubt the pipe will require any real FI changes....if anyone takes us up on the free dyno offer we shall see.

[mawayda]

Regarding the 4Road exhaust I was told by the dealer in GA that they are close to $400. He could not tell me (as it is already well documented here) what kind of improvement we would get. It seems to me that if you ceramic coat the exahaust or use a header warp that you could get better performance whith much much cheaper price. Whats your thoughts on that and has anybody tried that?

[micah apriliaforum com]

The price is $399 (free install and dyno for Texas customer) and they are in stock now. The package arrived yesterday afternoon. Call if you want the only pipe in the USA. It will be in the online Mall in a few days.

[bccatl2]

can the baffle in the stock Atlantic muffler be easily removed for improved acceleration or top end? or will it just add noise?

[sammyboy78]

I have been thinking about doing the same thing...removing that baffle, but I have to wait for the dynomometer to come in from the dealer. It should add some power because in effect you would be allowing more exhaust gases out at a faster rate, thereby reducing back pressure. This would allow more fresh air richer in oxygen to enter the cylinder for combustion. More oxygen, more power output:rollin:

Again, once the dynomometer is in, the service guy and I will do tests with and without the baffle, reprogram the computer if needed, and if all else fails, I think that one can reweld the baffle back to the exhaust pipe.

Will let you know when that happens.

Later

Sammy

[micah apriliaforum com]

How are they reprogramming the ECU?

[sammyboy78]

Hey Micah, to be honest I don't have that answer. The tech service guy told me about reprogramming. I would imagine the computer compensating for the fuel/air ratio automatically, but I could be wrong. In any case, when the dyno is in, we will check out the performances.

Sammy

[micah apriliaforum com]

Cool, let me know what you find out. I do not have an Atlantic here I have been slowed in development.

[Rebelck]

Has anybody tried the Leovince exhaust yet or any other brand? I am thinking of buying one for my Atlantic but I need to know first if there is any difference in power and noise. I saw yesterday a YAMAHA T-MAX 500 which had installed a REMUS model. Any comments are welcome.

[lcoop99]

I put a Leo Vince 4Road on my 250cc Honda Reflex scooter (aka Jazz and Forza). Very pricey to the front door ($361) but happy with it - like the looks, and being stainless steel, I assume it�fs the last muffler I�fll ever have to buy for the bike. You can remove a short �grestrictor pipe�h (term?) out of the back of it and the sound of my scoot went from �gputt-putt�h to a more satisfying (to me) �gold-motorcycle sound�h - lower, louder, more �gmacho�h - but still not too loud. (I would not have liked TOO loud.)

Did I get more �gpower�h - if so, not enough to be highly perceptible - only a dyno test would tell for sure. In that case I assume that any extra power is probably not much. My top speed seems about the same (80 on speedo, level ground, no headwind). - bike still seems to run well.

HOWEVER I SUPPOSE THE �gPOWER COMMENT�h above is really incomplete because the product also came with 6 new 24 gram roller weights for the drive pulley (�gvariator�h?) mechanism. Instructions just say �gput them in�h - haven�ft tried them yet but will eventually. I believe the 2-stage stock Reflex weights are 21g and 32g. Of course without also trying the recommended weights, I suppose the �gpower test�h of the new muffler is really incomplete. However if they �gcost�h me in top speed I will not keep them in. Hope this helps a little. (Don�ft recall any discussion about it, but assume the Atlantic uses roller weights also?) good ridin�f, --LC, Houston, TX
