I own a beawtifull 05 250x with the baffle removed, airbox cut, backfire screen removed, after market high performance air filter and pink wire mod..
i recently rejeted my carb as (no kit)
150 main jet
42 pilot jet
air screw 2,5 turns out.
Bike runs and starts just fine.
My question is if it is nessesary to change my needle clip posission (from #3 to #4) ????? or i'm just fine with theese jets?
if i do #4 does it influences the engine's reability-life time?? (except trial i also ride my bike every day in town so life/service-time is important to me..)
i ride at sea leavel at 40-90 temperature
Sorry for my english

Thanks!!!!!
