350x question

[threewheelin-feelin]

hey guys got 2 questions...i just bought a 10.25 to 1 compression piston for my 350x but im not sure what i will have to do about jetting the carb for it or will i have to change anything...question 2.. i misplaced my service manual so what it the stock tooth count on the front sprocket?

i think it is a 13 or a 14 tooth sprocket but im not sure

You probably wont have to change any of your jets, but you might need to run higher octane fuel. Premium or AVgas will probably be more then enough.

yeah i had one person tell me that about the fuel.. but i wasnt sure im a pretty good mechanic but im not good with modifying and wanted advice from some one who has run 10.25 to 1

13/40 is the stock gearing. Can't help you out none with the jets or fuel. fill it up with hi test and run it. the plug will tell you how its running. (or at least that's what I've been told) lol
