I am pretty sure the clips on the needles are in the right place. The air cleaner is a little dirty, but I took off the prefilter and it made no difference, I will try all the things you said tomarrow, this thing just runs terrible though, I am running out of ideas, I may have to take it to a mechanic to get it tuned Thanks for the help

Well I did more testing today. I put in 270's but that just made it way worse. I switched around the throttle cables, knowin that it was a common mistake, and that seemed to improve it alot, but then it was doggy as hell on the bottom end, Do you think going up a few main jet sizes would help? Yes I did get new plugs. I am about ready to get rid of this damn thing and I have only had it 3 days.

I also checked stator and that read 19 ohms so that is fine the problem started when my buddy loaded it up to bring to my house, loading it and everything else it ran fine, would running out of gas do anything?

when in hard accel it pops and loses power, every time it pops it tosses out a little blue smoke ok heres what i checked needle on 4th notch floats 21mm it has a 280 main with stock pilot reeds fine compression about 115-120 the plugs get pretty black after riding i think it is fouling them out, do you think it would be safe to go down to a 260 main i dont have any spare new plugs to do a plug chop, i may try that tomorrow though

I would say the mains are 280's cause thats what came with the kit.

i took apart the reeds and on the intake and reeds there is kind of a black substance that is wearing off, it almost looks like paint? It looks like it is peeling off the sides of the intake ports?

The plugs are actually dark, looks kinda rich actually. Not sure about the mains, my buddy just bought the Toomy t-5 kit, with the jets and everything needed. I think the filter and airbox are toomy too, well the prefilter is for sure. The temp is about 60. I am below sea level (minnesota).

Just bought a 2001 Banshee today. It has T-5 pipes and the air box. When I get on it pretty hard it is doggy. It backfires and misses. I bought it from a buddy and I know he took off the parking brake wire cause that was giving him a problem. Do you have any suggestions? I have cleaned the carbs and checked sparkplugs. What spark plugs should I be running?
