Hey Selector (Or anyone else who has input!!),

Hopin' you could help me out....I am thinking about going ahead with the cam mod and installing a 13:1 piston. I have some questions maybe you could help with since you're the only one I've heard talk about running the higher compression piston.

My bike is currently set up as follows:

Full carbon GYTR pipe, 168 main, 45 pilot, GYTR needle (3rd from top), 3 turns on the air screw,open airbox, GYTR dual stage filter.

1. Do you have to do anything to the bore size to install the piston?
2. What octane fuel do you have to run?
3. How is jetting affected?
4. Can you acually feel any difference in power or performance?
5. If yes to #4, is it worth the cost?

I really appreciate any and all info from anyone who has installed the piston and done the cam mod!!

Thanks , PH
