87 mm question
I'm looking into having Lowell do a 87mm BB kit for me.. I have this for jetting now,
1.5 needle valve
95 gram spring
120 main jet
95 pilot jet
I am at 500 ft above sea level mostly high 70* weather. half turn out on lows 1.5 turns out on highs.. Do ya think I need to rejet ?
Of course porting is in the quote.

imo, you should start with a 125m and a 115 pilot with the stock carbs. you will probably be ok with a 120 main and a 110 pilot, but i would start a little fat and monitor piston wash and rpm to be sure.
hope that helps.
