GhostRider Posted December 2, 2009 Report Posted December 2, 2009 Hi there... hey guys there's something wrong in my banshee .. when i go wide open in first and second gear its so fast and i feel like it's putting all of her power out, at the third gear 1/2 then it stops .. fourth gear is ok, five it does it again... i feel like its aint putting all of her power out... and it back fires at third gear/WIDE OPEN my mods are: porting, dunno what kind of porting pro design cool head bills pipes k&n in stock airbox and boost bottle jetting: stock pilot 25, main 270 left, 280 right... i'm at 90ft above sea level Quote
AKheathen Posted December 2, 2009 Report Posted December 2, 2009 jump up to 310 or 320 mains on both sides and sync the carbs. do a plug chop if it's running ok Quote
NickisGod Posted December 2, 2009 Report Posted December 2, 2009 i have a 421 cub and over night i lost 75% of its hp. culprate was i pinky nail size piece of papper towel that made it down to my float bowl clogging the main jet..... ya i hate to admit it this happened when i was cleaning my bike late one night after knocking myself out on my tecate Quote
GhostRider Posted December 3, 2009 Author Report Posted December 3, 2009 today i taken it to the garage, rejjeted it, 290 mains, i take it for a test riding the banshee feels better... but the problem didnt gone, its still aint putting her full power... so the guy at the garage said maybe theres shirts in the piston cylinder, he means the cylinders could be bored to the full size and the guys used shirts inside to grab the pistons on the cylinder wall... we still didnt opened the engine... dunno what to do, he said i must buy a full jetting kit, MotoX the red needle.. and we should try 320 main and changes the pilot... so what you guys think?

Velislide Posted December 3, 2009 Report Posted December 3, 2009 Try 27.5 pilots, and buy a jet kit off ebay with all the different jet sizes, sounds like it needs to be rejetted correctly, and remove any shirts, pants, bras, or whatever else is inside your engine, robs quite a bit of power. Quote
AKheathen Posted December 3, 2009 Report Posted December 3, 2009 hahaha, yah, no clothing in the engine....it's ok to run naked.....like i said in my previous post. and the ebay kits are great for every main you need pretty much, but has every size you will never need for pilots, so you will have to buy the 27.5 separately Quote
