Default 2002 CR250 questions

     

Iím sure this topic has been discussed, so send me the link if it has.
I have an 02 cr250, I already did the air striker carb swap, it has vforce reeds, an sst pipe and shorty muffler. Iíve already read the 97 cylinder has a more aggressive porting, so will that cylinder fit an 02? Eventually Iím going to send my stock stuff off for a 265 kit and get it ported for my style of riding and racing. But in the mean time, if the 97 cylinder (and assuming power valve) will fit Iíd like to go that route. Thanks in advance!

The motors are different. The '92-'01 had a mechanical power valve operated by engine rpm via a governor on the right side. The '02-'07 were the "RC" valve motors that have a powervalve operated by a servo via cables on the left side of the cylinder.
