Default Re: Newbie questions for upgrading

I agree on the jet size issue... these jets aren't drilled very accurately so investing in a set of small gauge drill bits, a pin vise, and even a set of jet gauge pins to verify the size of unknown jets or if you have several jets drilled and need to know which one is which...
Definitely let the engine break in before trying to tune it as it won't behave the same or make full power until after at least 3 tanks of fuel.
