O.K. update. I bought a new float needle and reset the float level to spec. The bike runs better than before for sure. I didn't have time before dark to plow the track so I ran it in the fresh snow on the lake. It pulls like a 5 should, power all the time when I would pitch it in there was plenty of power to keep the peg draging. I haven't had that much fun in a long time on a bike even though it was -10 below out. Hard to say how much it helped until I can get it on the track this weekend. A big thanks to everyone for the help.
