Kawasaki? or Yamaha? I had a yamaha rd350 shoved into a 3 wheeler back in 1980.
75 RD350. Spec 2 pipes, rear sets, milled heads and street ported cylinders, Wiseco pistons, 520 conversion, etc., etc.. It is a quick bike.
73 RD250. 350 jugs, Spec2 pipes and rear sets, Banshee Pro-Lite pistons, clutch upgrade, lower primary gear, milled heads (C12 only) and ported cylinders. Real quick bike.

That's a blast from the past!

I had also posted about this on the cal-look forum a couple years back.

Steve is still in buisness, but has had a tough go with health/family issues.

His street car at that time was a '73 Westy with an RSR spec 2.7L flat 6. In it's NA form it was quick and made some decent $$$ onthe street. He then turbo'd it. Crazy fast. It would pick up the tires, and the windsheild would pulse winding out 4th gear. Good times. The motor was fed with mechanical injection. I think it was a SPICA pump which he heavily modified. I remember many test runs followed by pulling apart the pump, grind/weld/machine the 3-D cam lobe in it, and give it another go.

He always played with engines. Built a Kawi dragbike, and played with a sled in his early teens. When he was 14 he built a motor for his older brother's(had a drivers license) street bug. Went down to Farmington with it in the mid 90's and won his class. Ken Fisher back then took a liking to him as a kid. Pretty impressed with what he had built. He came back many years later with the 2-stroke bug.

He built a few versions of that 2332, going for the 9sec record that was held by our local BLY & Siegfried racing bug. It ended after he blew a cylinder due to hydraulic lock on the Methanol 16:1 mechanically fed 2332. That motor could rev, but couldn't get into the 9's with the rear engined/type1 box bug. So he bought that front engine project bug, and finished it. Was planning a Pauter engine for it, but couldn't come up with the funds. So looking around the shop he figured to build a type4 2-stroke with the parts and materials he had in the shop. So it was all his labour on a shoe string budget going back to his 2-stroke tuning days as a youngster.

Here it is firing it up for the first time in the shop, a couple weeks before the '01 IVWA race:

I spent a ton of time in that shop that summer. He helped me build my EFI 2332 at the same time.

Exhaust expansion chambers, the cylinder's transfer ports, and piston were made with input from my Go-Kart engine builder. My Rotax 100cc rotary valve 36hp kart engine was replicated for piston and cylinder fluid transfer timing.

That 2-stroke bug is still around in storage.


Pic was taken at the '01? IVWA race at Farmington. We trailered down 3 cars for the event. That 2-stroke was ridiculous. Sounded incredible. I ran my super down the track for the first time, and lost running a 8.16 on a 8.14 dial in.

After the 2-stroke bug, he built his RX7. Peripheral Port 3-rotor turbo monster:

Check out the slide valve he made:

Last year when i last visited, he was working with some Mazda engineers for a ceramic Apex seal design for their race program. Had just come back from England where he tuned Andy Frost's big block. He flies out there often, ever since Andy Frost went to Electromotive EFI.

Steve is a real smart guy that thinks outside the box on all fronts. He gets bored easy, which explains his many projects.

I should go and visit him this week,
Pete
