    I'm thinking of going with a 102mm 10.75 piston from JE. (I'm thinking 10.75 cuz I want to still use 91 octane, and hear that 11.1:1 will be on the boarder almost having to go to 93 since I'm getting a high compression piston) Are they crap or good?

    I'm wanting to go with an 11.1 hi comp piston when i do my big bore 686cc next riding season. Also I will probably be adding a stage 1 cam. I know stage 2 is better but I need to save money somewhere☹️. Can I run 91 octane? That's all we have around here. 02 raptor 660
