[QUOTE="usgpru27, post: 870129, member: 58332"] Old Parts... Man I need to change my mentality. You are correct.. On our Roadrace bikes we change pistons every 250miles or 3 hours. Cranks are replaced at 1000 miles or about 12 hours. Along with this every clip, bearing and seal are also replaced. Cranks are balanced and the entire engine is bluprinted to some VERY close tolerances. Typical rebuild is about $1500.00 But since we are getting close to 42hp from a 125 motor that may explain a lot. And we run them 9000 - 13500 when they are running. It is my understanding that the 01 CR cylinder has the same port configuration and port timing as our teams RS 250. I have a lot of experiance with this and plan on changing some of my CR stuff to get the delivery I am looking for.. This is great stuff... 1 mm squish.. Wait till I call my engine builder.. !
