Hi all;
I have posted here a couple of times, have an 03 K5 I am doing a top end rebuild on, ( yes, I have checked the crank play, and seals, all good )
My question now is whether or not to have my new piston window cut??? I have read most of the threads on top end rebuilds, and various other topics.
I have done the porting clean up, and wasn't planning on doing any other mods.
I am using the bike for Ice Racing, ( run 4-5 gear mostly ) and the bike only gets 3-4 hrs a year running.
Need to have some advice from guys that have had both stock and window cut pistons, and what is the difference??
Cheers, Wopper
