I recently installed an SIP 3.0 exhaust and changed my P200 to a 120 main jet to complement it (I made no other changes). It's not delivering quite the over boost I hoped for (though I'm happy) and I was wondering what jetting others are using with it.

If you have a 3.0 how did you jet your carb? I've got a standard 24/24 carb. The 120 should be enough but maybe I should change out the idle jet and boost the main jet further...122? Did you change your timing?

4-6 points higher is what's usually recommended.

What part of the rev range were you hoping to clean up? If you're looking for acceleration, do the heart mod to the air filter.

What exhaust did you start with?
