Serious help with jets

[Motoman]

I just bought a 1997 Banshee from someone and the carbs were rejetted. He has Bill's Aftermarket pipes on with a K&N filter with the lid on but it has vent holes in the lid. The quad idles fine but when you give it up to about a quater throttle it boggs. He put a #310 main jet and a #35 Pilot he also put a new Moose needle in DNO304, I dont know what notch he has the needle clip on. Im really not to much above sea level, I live in New Jersey and I really dont ride in temps below 50 degrees. Could you please tell me the proper jets to use and the notch on the needle. These Jet thing drive me nuts.

 

Thanks,

John

It's way to rich, I'm gonna say try a 270 main and stock pilot (25) with the needles on the fourth clip if everything else is stock. You may have to go up or down a size or two with your mains but I think that would get you close w/ your lid on.

I agree 100%. Unless you're running alky through that bike, I've never had to use larger than a 30 pilot...

 

Stock pilots should be just fine, I don't know anything about that moose needle....I'd say go back to the stocker, or get the Toomey/Dynojet needles or the Vito's Needles....

Even with the Bill's after market pipes should I go back to those sizes?.

Yeah, you'll be really close with those jets.

[dajogejr]

Yep, you are WAY fat on the pilot, and a little rich on the main.

If you removed the airlid, your main would probably be a hair rich, not much, but your pilots are WAY out of reach!!

I do have #280 mains and #30 pilots. Would this be ok or do you strongly recommend the #270 main and #25 pilot?. Whatever you think is best.

You're either gonna need a 25 or 27.5 pilot depending on elevation and riding temps.

That DNO 304 needle is a dynojet needle packaged under the brand name Moose :thumbsup:

My elevation is not very high from sea level and I wont be riding in temps under 50 degrees. Would the #25 do it?.

[banshee dave]

run the 27.5 pilot. Than adjust the air/fuel screw to about 1 and a half turns out to two full turns out. run the bike on idle till it warms up than hold the thottle to above idle than bottom out the air/fuel screws. this should bog down the motor but don't worry. if it dies, restart it and hold the throttle out a little more. Than start to turn the screws out until it idles to its highest point which should be the one and a half to two turns out. if it idles out at one full turn out you need to richen up the pilot. If it idles up past two turns out you will need to lean out the pilot. As far as main jet, if you are running the stock carbs and no motor work other than the pipes and the airbox lid on and the stock airfilter if that is what you have, I would start with a #290 and do a plug chop. At just above sea level it should be near spot on, but not every bike is the same. Hope that helps. :thumbsup:
