Crf ignition with high compression piston

[depotman19]

Hey all! I am wondering if anybody has any info on crf ignitions going into 450r's with high compression pistons. I have heard you have to alter the degreeing of the stator a little differrenly than if it was stock compression. Can anybody explain this to me?

Thanks Jake

Yeah I know it can be done mine is suppose to be here today. I was just wondering what needs to be done differrent in regaurds to a high compression piston. They setup the spark timing differrently than if you ordered the kit for a 10.5:1 piston. I just want to make sure I wont get any detonation with them messing with the spark timing?
