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.

HELLO, my name is stickers!
Catch me if you can
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
