• Looking for a good starting point for a LT500 engine with an Aaen hybrid pipe mild porting,head recut and O-ringed and stock 38mm carb.Not sure how much richer the main jet size changes over stock with basically a change to an Aaen.I will start rich but how much richer than stock would be a good start point?

• they tune about the same as a Q pipe.  start around 440-430 main 32.5 pilot (>1000 elevation)

  Is that even with a stock 38mm?I was told to run those specs with a Q RX,d carb but thought a stock 38mm would be leaner jetting?

• I'd run 460-450 main and 35 pilot+ depending on slide wear with a bored 38.

• It's a non bored stock 38.
