thankyou, so quick question, jetting=i ride at 1000-3000 feet, has fmf with spark arrestor, stock air box, with 6 1" holes in the lid and a K/N filter with outerwear, stock carb, stock cylinder that is supposedly bored .20 over, i bought it outa montana and he reported elevation at 3000-5000 and he was running a 145 main, and a 50 pilot, which from what i can tell will be lean for me, as stock was a 150 main i believe, now with the pipe and airbox mods I have bumped to a 165 main to be safe, anythoughts on if im headed in the right direction? he was also running a b9 plug and i thought a b8 was stock?
