Hi John,
Obviously, a lot of water has flowed under the bridge since you started this thread. I am wondering if you would now recommend adding windows in a 500cc piston to help lower piston/combustion chamber temps and are there any downsides?
Also, do you still have those pics?
Cheers,
Rob

G'day Rob, I never ran the CR on the dyno, so I can't talk on HP, I also did not run any temp strips on the engine, nor use a temp gun on it, I can tell you that my CR did not ping, it was very high compression, enough to split the plastic cup in my artificial knee. CR500RE's were infamous for pinging, if I ever have a bike that has a rear boost port, I'd put a window in the piston, if it doesn't have one.
I'll see if I can find some pics, send me an email;
