TSS-RS500GP..........(round 3).....cylinder problems?

[50Joe]

No PV's on my racer. I'm a high RPM rider so I don't miss them. On the street? Depends on your riding style. My bike hits hard at 6800 RPM and carries to about 11,000 RPM. Like lt1bird said, run them rich and make sure they are fully warmed up before getting on it hard. I change pistons and rings about every 600 race miles. This keeps the cylinders in great shape. On the street I bet you could run it for thousands of miles.

2 races - 2 wins thus far this season.

Thanks for the info guys, lm itching to get this thing going, at the moment lm working away so work on the bike will be limited, l have a spare RG500 motor but l don't want put it in as that was not the idea from the start, Steves idea of a 500 two stroke with new technology is a fantastic and inavative way to go....... Between himself and people like Smads the project will get there in the end. And when it does what a machine we will have...

Hey Steve any chance you could post the pics of my bike?

[smads]

Hi jacko
My engine is in a rd350lc frame I can just imagine how great it would be in rs frame omg!

We will all get there in the end....few painful hiccups but hehhh.

Thanks to Steve I'll be back soon

Porter is another two weeks and the ceramic plating another two weeks but I'm excited again.

If any of you see practical sportsbikes uk mag my bike was in it two weeks ago.

And yes I did 300 miles on mine very rich then dyno man took it down from 172 main to 158 because it was so rich....It did 80 after but in hindsight it never seized rich!

pipes on non powervalve 421cc athena..looking on, waiting for solution on 485 race bike..good work guys

It's great to hear a bunch of different perspectives on here, especially about non-PV and PV engines. It would be sweet to see some onboard footage from PV and non-PV bikes, so forum members can vicariously 'take a test ride' - well, at least to visually see how the different engines behave.

Of course it's not straightforward for people to just take a test ride on these bikes 'cos they are not conveniently sitting at dealerships with trade plates on for punters to have a blat - but hey, the more perspectives we get on here from owners of these hybrids and monsters, the clearer should be the picture for everyone. I see the argument for a hard-hitting non-PV engine - a performance-enhanced LC in some ways, with all the fun that brings - and I can also see how desirable a PV system is in a very brutally powerful stroker motor in a lightweight chassis with a short wheelbase! I think a lot of it depends on what individual riders are comfortable with. Or what they feel like riding that day! In an ideal world, one would have a whole stable of bikes, each with different personalities, and ride the one that suits your mood that day.

And the term 'unrideable' when applied to 100+HP non-PV stroker motors is a matter of perspective. If 'unrideable' is meant to say it's a dozen handfuls to try and cut fast track laps on, then the description would hold true. A powervalved motor would be a better tool for the job.

If 'unrideable' means that you simply cannot crack it on through the powerband in traffic and thus have to ride it bogged-down out of the power for fear of wheelies or other mad antics, well to be fair ... some people wouldn't necessarily mind that too much - while for others it would be unacceptable.

Each of us know what we like in an engine. What's harder to project though is the reality, the eventuality of what these things are like to pilot. They are many times more savage than an RS250 or an RD350 YPVS. And hurrah! we say!

I have to say, it is truly astonishing to ride one of these things, flat-strap on the tank in 6th, and feel that ferocious wallop of power come hammering in and lofting the front wheel. It feels like all the motive power on Earth is compressed into that singular horizon-hurling power hit. Utterly loony and I love it.

Very few people have experienced what it's really like to ride a super-lightweight stripped-down race RS with carbon wheels and what-not, with a 100HP+ bomb up its frock. It's not what you think it's going to be like at all. It's riding a motorbike, sure - you have the same controls as everything else - but your brain just is not calibrated for the amount of ground the bike can cover in such a short time-frame, and you find yourself arriving at points on the road or track well before you had expected to be there. These things can boogie and when they do, they can take giant strides. They're loony enough WITH powervalves!

The thing is, it doesn't matter how savage the acceleration is ... I mean, if there were a bike out there that could accelerate at 3G (and not flip) then yeah, you'd hang on and gibber, and then end up panic-braking, and arrive back home laced with drool. And go do it again. The thing is about acceleration, it's a great sensation, and you don't back off when there's more of it on tap than you've ever known. But what you don't really realise at the time is the pleasant sensation of increased acceleration is also accompanied by chunks of road covered in greedier gulps than ever before. That insane acceleration results in insane speeds. And on the road, it feels a bit like you're a highwayman - you know, a real bogey-man. Highly bloody illegal, and strongly enjoying it.

But the whole point of it is to have fun isn't it, to have a truly loony bike. And they can come in many different flavours; from jalapeno peppers to habanero chillies!

Sure Jacko, here's that pic of your bike you sent to me:

[smads]

Wow jacko looks nice are they carbon wheels?
Have u still got pic of mine Steve?
Not as nice as rs but fun to ride!

And Steve your so right I got caught out quite a few times driving mine,it arrived quicker than me lol..also I have a 1/4 mile straight outside a police station right by my home , I came off lights lifted front looked left at the shocked officer going other way...lol...priceless!
When I can afford it I'm buying a go pro camera for a blast.

pipes on non powervalve 421cc athena..looking on, waiting for solution on 485 race bike..good work guys

Are that the TSS pipes? Have you used them with the Athena?

Interested because i´m about to build a engine like that.

[twostrokeshop]

Hi Rallykay,
Yes those are TSS pipes on the Athena. They work really well with the Athena 421 engine. Actually Joe, have you ridden Jim Hinshaw's bike with the Athena 421? Oh and also did you have occasion to ride Jeff Crowell's TSS/Athena RS421 with the Athena pipes?

I know Jim has won races in his class, and cut lap records on an Athena 421. Just the other day he said he was within three seconds per lap of a very well-ridden TZ750! Jim said he really likes the Athena because it's not so violent when it comes onto the pipe, and therefore more rideable in more situations.

I've scribbled a few notes about the Athena 421 and machining engine cases etc. on this page. http://www.twostrokeshop.com/Athena_...engine_kit.htm

I've only just uploaded it; I will be adding more over the next few days.

[slowpoker1]

Steve, i see you are selling the athena kit, I assume you are going to send these engines to all paid customers. All seems to be forgiven with the engines that dont work properly, Guys like smads are working hard and spending their own money to fix your mistakes. Pitiful

[twostrokeshop]

First of all slowpoker, if you want to come on here and start trouble, you're heading in the right direction. For the record, I am doing everything I can to try to solve the issues THAT I DID NOT CAUSE, MIND YOU! The issues of which we speak, I blew the whistle on, and declared the issues as they are, and stopped the rot before it went any further. You will note that the bloke who caused all the issues is absent. He hasn't the decency to show himself on here.

For the record most 500 customers rejected the Athena solution - even as an interim measure - out of hand. Also for the record - those who have accepted the Athena option, I have sent kits out to them, or I will soon be sending their kits out.

And you will notice that I am the only vendor who lays out the steps required to modify the top engine case for accepting the Athena cylinders ... which is something most gloss over in a disingenuous attempt to market the kits as 'direct bolt-on' setup.

And for the record I am spending my own money trying to sort out the 500 issues. I am trying my damndest, despite having been driven more than half-crazed by all this, and despite being driven financially to the wall. I am still in here plugging away - and please, good heavens, forgive me for trying to sell parts from the shop to keep afloat. I had better just piss off and go bankrupt had I? I'm the only one on here trying to do something positive! The other guy has said "Seeyalater" and has ridden off into the sunset with some $150k worth of parts!

And for the record, I have dug deep, into every penny I have, to re-purchase as many parts as I can to supply customers with parts that the other guy either messed up, or parts he ran away with.

So you tell me who is trying to do the right thing. It's very easy to sling arrows, and I know full well it does not matter what I do, I am damned if I do and damned if I don't.

I have to try to SURVIVE if I am to help turn the 500 situation around. If you can't accept that then too bad.

I am heartily sick of the acrimony on here. If you've something constructive to add to the mix, go ahead. But if not, it's just a pain in the arse for all of us.

I am just about sick and tired of all this shit. I've put everything on the line for this, and I continue to do so. I have been played a very shitty hand, and I'm trying to make the best of it. It seems it doesn't matter what I do, I'm going to get sledged. Happy happy times.

Just keep pushing, just keep sniping, just keep accusing, and I'll just pull back and wash my hands of the whole thing. I do not have infinite financial resources, just the same as I don't have infinite emotional resources. And I'm heading along exactly the right trajectory for a divorce, and losing what little I have left - including my sanity.

Fuck's sake, let's work together on this and try to help each other.

[slowpoker1]

150,000 of our money, You are the one i sent my money too. I still have every email with all of your lies, Just want everyone to be aware. Work together? We are the ones who gave our hard earned money for YOU and Wobbly to piss away. That is all i have to say, just everyone beware.

[twostrokeshop]

Okay then that's the end of it. I shall contribute nothing further to the 500 project. I'll piss off now then and do a Wobbly.

End of.

[Jacko]

Yeah Smads it has BST Carbon Rims and a RS Honda front end with an Ohlins rear shock.
Hoping for a 1-1 power to weight ratio at the end. I have a very very quick ZRX 1200 which has 179 hp@ the wheel and weighs about 215 kg so if the Yammarilla can go close to 1-1 would unreal.

And as we no there's nothing like a Two Stroke....

[smads]

Slow poker Steve has helped me on every bit and has never disappeared a lot of us have realised that Steve was left to sort the shit.

Steve is trying to keep his business going ,if it fails so do our spare parts and links to the people who made them!

Instead of bringing this thread back to slagging keep it on tech and help......

Yes I'm spending MY money but Steve is also helping to solve the issues.

No one in this world is perfect but Steve is trying to right the wrongs and help sort people out....I was offered an Athena kit but I wanted to spend my money and work out what wobbly did wrong.

I thought we had stopped the finger pointing and got on with some proper two stroke testing ,building and driving!

Let's keep it helpful and technical

:-)
