I was out the other day, East coast Canada, -6 degrees c. The bike worked pretty good except when I let off it would sometimes "fast idle" then come down, didnt think it was too serious but the first time it happened I was suprised, "big spurt, holy @#$^&*(" Should I up my main jet a couple of sizes to compensate for more dense air. As well could the pilot have anything to do with the jump in rpm when I let off, since its operation is from 0-1/4 throttle?? Perhaps it is dirty.
Thanks
