Hello, My 2006 runs great when I first get on and ride for 20 min or so. Then I noticed at a light that the idle was becoming eradict. I had to give it lots of gas and release the clutch slowly to get out of the way. When I get up to speed things seem to smooth out but its when I am stopped when things start to go wrong. Its shut off on me at lights more than once. NOT GOOD. Any ideas?
