640cc KX
SandToyz:
How much stroke you can go with the KX?
i do mine, 2mm stroke and 88 piston with custom CPI pipe out of frame

I'm stroked 6mm. I'm also using a longer rod and a 91mm bore. I have a 1/2'' spacer plate between the base and cylinder. This is a new motor to me, yet to fired. Last year it was a 540. I'm glad to hear of another stroker. The guy who did my crank said there was 3 or 4 more of these out there, supposedly a couple in the sand and one in Canada ice racing.
crazyryan:
SandToyz, Is there anyway you'd send a pic of your bike on the exhaust side? I've never heard of CPI. I'm probably going to get a out of frame pipe, I'll just put it low, like the bottom pipe at the same height as the footpeg. If I lay it over on that side, I'll just have to fix it or replace it. I'd really like to have the absolute best pipe for this motor as possible. Please show the pipe to me. Later
