[QUOTE="Fred T, post: 113501, member: 22413"] I have had real good luck jetting wise with a stock 145 main after adding FMF rev pipe, airbox mod and raised needle second from top. I have Boysen reeds and they claim I need to lower main jet so I was wondering if anyone has gone that low with these mods? Ride temp is 70-90 degrees and I have no idea of sea level (Northern MI) I know and understand about plug chops but I can't ride my bike around home at all (WFO down the street is a no-no) so I have to jet on the trail and that's not always possible if I have people waiting for me to pull the carb off.
