I know the answer I am looking for is probably answered in a thread somewhere already but I'm looking for a quick answer because I need to place my order tonight. I have a 2002 Yamaha Blaster with FMF gold series pipe and silencer, open air box and v-force reeds. Other then that it is stock. Just did a rebuild because the previous owner ruined a brand new top end because it was running lean due to poor jetting. I am in upstate NY with temps between 55-75 normally. I am thinking a 300 main jet with 32.5 or 35 pilot. Please let me know if this is right. Thanks!
Jetting question

what was the poor jetting at??###
you really should leak test it first otherwise
all the jets in the world wont save your engine
it either blew from too lean
airleak,improper piston to cylinder clearances....ect
list goes on..

yes, 230 is stock
stock 32.5 pilot, airscrew @ 1.5 to start, tune for highest idle
stock needle on middle clip position
buy 270 thru 310 main jets
start large and plug chop down to perfection, or +1 size up to be safe
you should fall in the 270-290 range, but I always suggest 1-2 sizes larger
it helps to learn plug chops and tuning down from rich, plus you'll have larger jets for when the temps drop down into the 50's - 30's
Thank you very much. Exactly the information I was looking for. Should I leave the pilot at 32.5 or up that one size too.
