Well………………. end of 2010 now, where the fuck are they?
Who has got a RS500GP?
Who has a completed motor delivered?
Where is the test of the 1100cc two-stroke Zx10r? All piss and thunder about that then nothing!!!

This is behond belief

TSS are so full of shit.

Other manufacturers deliver. They just wank.

Talk about a golden oportunity wasted!!!!

enough said.

And… anyone who is in mid-40s and didn’t spend time building and racing RDs or RZs has some explaining to do.

Yes, I can make a fair set of pipes when I need to

but I know it can always be better, so I’m not going to get too cocky.

This comments board isn’t so we can get into a pissing match over who has more credentials… is it?

I am currently building a 500 cheetah going in my RZ,steve has been a wealth of information and advise,and hasnt tried to push me to purchase any of their parts.

I have been building and racing rd’s and rz’s for over 20 years,and know horse shit when i hear it.

I’m trying to stay upbeat bkz there aren’t many guys trying to do this. I believe they have a US distributor now..??

Rick Kovacic of sportcycle racing said they are going to take an RS500GP racing with the AFM this summer (California) and that the prototype was being assembled stateside.

I invited them to bring an RS500GP to an AHRMA event at Barber motorsports park, but that will be later this fall. We’ll have to see what happens. Maybe the light is at the end of the tunnel? Sounds like it is available for sale?? I have not heard from any current owners, tho.

peace out

I’ve built several sets of expansion chambers as well; however, instead of assuming that I’m now a GP pipe designer, I now realize that there’s always a better design out there. And the pipe design I spit out using TSR just maybe won’t be as good as one that comes from a guy who designed pipes for competition at a world level. Call me crazy. There’s a lot of subtlety in making a pipe, and knowing how to optimize for a particular engine is trickier than using a tuned length formula.

You have two RZ350 engines, with the same port timing. both have same projected peak RPM. OK, so you come up with a pipe design. Now, what if the transfers are changed to flat-tops? what if compression is raised? what if he stuffs the crankcase? what if he’s going to race at high altitude (Pike’s peak). How do you alter the pipe to optimize for those changes?

That’s when a guy like Wobbly is probably going to know which direction to go, while the book is going to hand you the exact same pipe design you started with. That’s all I’m saying. I have always sought advice from more experienced pipe designers, when I can get it, because they have insight and experience that I lack. The book is a starting point. A lifetime of experience is worth a little bit, no?

I heartily commend you for designing and building your own pipes, of course you know that puts you in a pretty small minority as far as 2-stroke self- tuners go.

We won’t get the latest PB for a few weeks, probably. I’ll have to check it out! My buddy built a similar project, with 480c monoblock RZ motor in an RS chassis. I haven’t ridden it yet, though. I have not heard a peep about Stan’s 535, is it a one-off toy or something he plans to market in quantity?

I still think it’ll be something fantastic if TSS can get this bike in people’s hands in some quantity. Lets face it, interest in 2 strokes is dwindling fast (at least stateside) and if guys were out doing trackdays on a good looking RS500GP maybe it’d spark an interest in a few 4T guys.

I ride, race and do trackdays on an RS250R Honda, it goes well but I think it’d be even more fun with 35 more HP. Guys in the pits are always interested in the little screaming bike that got round them in the last session. But not enough to make them go buy one. So I’m very keen to see what TSS achieve with this bike. If I said, “yeah, it’s an XYZ500, you can go buy one yourself” just maybe they’d have a look into it.

I have an RG500 but it’s so old, and parts so scarce, the thought of a new machine with available parts like the RS500 has got me going. What can I say.

Peace, brother!

“The individual components may not be earth shattering. But has anyone else built a new, no-compromise 2T lately? And not some bastard garage-built special, but a bike that (hopefully) will hold together, run hard, carburete well, and handle like a real racebike? That’s what’s exciting”.
Read the latest UK PB I think you’ll find a RS535 that stan stephens has been racing for some time now
