hi, i have an 86 trx200sx with an atc 200s motor in it. i was wondering about jet sizes. i ride at an altitude around 800 to 1200 feet, i have stock jets with aftermarket intake filter and fmf slip on exhaust. with this combo do i need to up jet pilot/main to get the most performance? will jetting really do anything over stock jetting? also, what does changing the needle clip do? someone said there was 3 settings on the throttle needle.
