Thats pretty interesting. Awesome picture. Why did you choose to do the GS? Just messing around with what you had? Or do you like the motor?

It's a nice air cooled twin, the regs were pretty 1990 air cooled so it fitted in quite nicely. I'm looking into building a more powerful one for next year, anyone know anything about tuning these engines?

We ran 100mph from a standing start over 5/8th of a mile on sand, fastest was a Spondon gixxer turbo at 140mph so we didn't do to bad, there were Brough Superiors there, a methanol burning Triumph, a super charged Indian and a Vincent streamliner among others, proper cool stuff!

That's really cool!  :thumb:

... The exhaust can.. Just a modified assembly right at the header spot! ...  :D ... How noisy is that?! Lol ... I Understand its for weight saving.... But I don't reckon other "a loud exhaust is a good exhaust" aficionados around here have anything in noise compared to that!! ..... Heheheh  :thumb:

I ran out of time with the exhaust, I just reasoned that the shorter the better for running flat out wouldn't be to far wrong, it will coming off this winter for a tuned length header once I have done the maths! It isn't anywhere neat as loud as I had feared, many louder bikes on the road.

We had an older member round the time i joined here in 2003 took a gsxr600 engine, shaved the outer two cylinders off. and raced it. the staff here, mainly kerry, buddha pandy and pablo will know of this one. But my friend, i WILL follow this. this was a gorgeous pic

That GS/gsxr hybrid is very interesting, I enjoyed reading about it however it might be a little to far away from the original engine for me. Has anyone on here got any experience building tuned length exhausts for the GS?

Interesting looking bike!  (and with no rear shocks.. painful looking too ;) )

one thing though: if it's "built for speed"... wouldnt it help to put some kind of fairing on it?

He's probably running a No-Aero class.  They are cheaper on the pocket.

Watch this space on the aero front, its currently in the workshop having lights etc added for an not but this winter I'll do some work on the aerodynamics!

very cool! Performance wise with the GS you can achieve around 550cc using some kawasaki GPZ pistons (i think) you will find it pretty quickly on a search. I'm not sure on the availability on them anymore but wiseco used to do them.

Good Job

Actually, it was a GSX-R head mated to the GS500 cylinders and bottom end. Not that there was much left of the original GS500 engine, other than the tranny, oiling system, and cases. He had a custom crank, rods, pistons, etc.
