I just installed Toomey t-6's on my stock '04 banshee. I followed the directions to a T. I installed the 280 main jet. I ride in Michigan and its about 45 degrees. I replaced the stock needle with the one from Toomey and put the e-clip on the 4 groove from the top. I also adjusted my air screw to 1.5 turns out.
Everything I listed above is in the directions to the pipe.
I thought It was kinda sluggish in the lower end until I rode a friends shee with a FMF fatty. Now I know it is sluggish. His is allot snappier. He has FMF fatty's, 280 main jet, stock needle, and he cant remember what size but he did change his pilot jet.
Mine was allot more sluggish on the bottom end. But, when I hit the midrange and top it it screams!
I checked the plugs and they were a little black but i could see more brown than black. Sound like its running a lil rich?
I called Toomey and their tech support told me to put in a 290 main just because it was so cold here. 40 degrees cold? Maybe in Cali but here its great riding.
Anyone out there have a simular setup? Or know how I should set this thing up for the weather now. Maybe give me a break down of how to adjust it for now and how to in the summer. I also put on the 2:1 high flow air kit. Stock air box gone, Uni-two stage with outerwares. Thanks
