Sum 1 Please Help me with My Banshee


Recommended Posts

Hey whats up guys well i just bought a 06 yellow special addition banshee and threw a bunch of mods on it. I just put toomey t-6 pipes on it, v force 3 reeds, reed spacers, carb rev eliminator kit on stock carbs, k&n air filter kit, and i have a 400 main jet in it right now and a 27.5 pilot. The plug is burning perfect but the quad on bottom end just seems like when its running it the choke on. when it opens up though it rips. i was going to flow port and polish the head, shave them and throw some different pistons in to see if that will do anything. Alot of people told me you have to have a little motor work done not just bolt ons to really make the t-6's open up, they are ALOT fatter than the t-5s and i was thinkin that i need some more compressiion to make the pipes work.. its almost like the pipes are bogging the motor. and theres no way i should be up to a 400 main either people said. i don't no whats wrong with it i know thats its not running right. any suggestions would be much appriciated. thanx again..

T-5's respond better to motor work than the T-6's will. You didn't give your elevation so I'll help as best I can with my elevation (1000ft). 400 mains are too rich, try somewhere in the low 300's. Since you say its too rich on the bottom, try dropping the needle a couple notches (raise the clip towards the blunt end). Different pistons will make no difference. Good Luck.

sry thats my bad i live in PA and the elevation aroung my area is 2000-2500 ft. i tried so many diff variations with those carbs bet i had them off and tore apart 100 times if not more. people tell me that thats how the banshees are with the bottom end bog but i rode them b/f and this isn't running right at all.. its like when you just punch the throttle on a low end bog the motor just burrrrrrrrrrrrrrrrrrrrrrrrrrssss alomst like a bbuuuuuuuuurrrrrrrrrrrrrrrrrrrrrrrrrrrrr its HAHAA its hard to explain then as it starts to pick up R's it eventually with kick in and take off.. but sometimes its bogging so bad it won't come back even with the slip of the clutch. see i'm a big hilll climber and when i am climbing hills with is it just dies and we though it might be the floats but we adjusted them and there good now.. cause when i would pull my air box lid off with i have holes cut in the air box would be full of gas. i'm tryin to explain this as good as i can i just wish sum1 who actually knows banshees really well could just be here to see what i mean.. again thanx guys for the help

You definaltley sound rich. There is a great thread in the jetting section. Jetting takes time and experience. I find that you get the best results by tuning one circuit at a time and making small adjustments.

It could be a mix of being lean on the pilot and rich on the main which is giving you a decent plug reading. When you are at a stop and you stab the throttle does it almost stall out? If so then thats normally a lean condition on the low circuit.

way rich on the mains. ive never played with t6's and vforce reeds but id bet you need to be around 260-270. needle on the 2nd clip from blunt end.

 

start with 300's and needle in the middle and work youre way down.

 

remember, 400 is way too rich for that engine and that elevation.
