I was wondering if anybody has installed a high compression piston on there YFZ or if anybody has any info on them. The only one i have seen is from GYTR.

Im thinking about installing one of these on mine but just wanted to make sure i was making the right choice on which to get.

 

i take that as a no...... i dont have a problem with the GYTR just checking

 

Couple guys on other forums reported having problems with the GYT-R pistons(JE). Some thought there might have been a bad batch of them...but there is about twice as many people that said they liked their GYT-R piston.

You do have to run race fuel with the 13:1

 

Bump.

It's been a while.

Who's running one? What kind of power gains have you seen?

Anyone have any issues with it?
