:: I have a 2006 banshee special edition mods are listed.The bike has only 10 hours on it.I installed a full fmf fatty power core 2 exhaust on it and did not jet it.The stock jets are#200 It was running prettygood all through the gears except when i got into4,5,6 then it would bog down and backfire/make popping noise out of exhaust.I've since installed the jets that FMF sent me #260 and now the bike does the same thing but way way worse.At idle if i blip the throttle it just bogs down and shuts off.I am running twin k n airfilters w/no airbox.I live right at sea level and the temp now is between 40to60.Any info would be greatly appreciated.
