raptor 660 pilot jets
#4
Ok thanks.3 turns out max.The air box is closed I just cut the flaps in the snorkel and the trimmed back the flaps in the air box cover so it will suck more air.The exhaust is stock and I also changed the main jets to 145/150.I thought it was going to run rich but the spark plug looks good.I guess it was a little lean from the factory.
