Well here's just a quick build to try and produce something raceable from something that looked pretty but was not. Pete saw the pics of the Orange NSR on Tardme and bought in faith.
When it arrived from Auckland clearly all was not well. In no order, the brakes were useless, the crazy big rear tyre made it handle like a truck, it was also offset to one side to get it to clear the chain. Uh Duh!
Supposedly the bike was faster than a warm FXR. Clearly that was a lie. The bike had never been raced I'd guess and the clutch slipped so bad it was a joke. And it vibrated.
Engine out and in my garage. Clearly everything ignition, carb, and mostly the porting were stock. The crank looked rebuilt and supposedly it has a TS gearbox in it which provides better ratios. We'll be checking that obviously, but there is a spare bottom end and that is a TS.
So the plan is to build a petrol push and ride engine for my good mate Pete that will give him the 2stroke fix he desires and be more competitive than his mostly stock FXRAGH. It will want to be grunty as it has to pull his, er. . . manly carcass about the track.
I decided we weren't going to stray into too much development. Just built with good parts which allow more power through good engineering.
At this point I'd like to thank our benefactor TZ350 who super generously sent some GP clutch parts, an RGV250 rodkit and all manner of odds and sods for the build. As well as some good ideas. GPs have an extra clutch plate and the inner basket swaps over. The outer basket has a different gear and matching gear doesn't fit the crank.
But the basket was better with less slop so I swapped them over and helicoiled the rivet holes and bolted together with lots of studlock.
