Hey guys, need some advice. Let me start by saying that I have owned this bike since 05. It has never given me a bit of trouble and I have been religous on maitinance. Last year at this time I bought a new ktm(I know I know) and this bike sat out last riding season. I started it up last fall and noticed that it was missing a bit, like it had junk in the carb. I made a mental note to clean it out this spring. Well, spring is here and I was hoping to get this cleaned up and sold, but I can't get it running right. I have cleaned the carb, jets, everything three times, and then did it again. Gas is fresh. It starts right up with the choke on, throttle response is quick and responsive. As soon as I try to turn the choke off it dies out without me feathering the throttle. I have also noticed that when this happens I can hear air? being blown back into the tank. Sounds like big air bubbles. Anybody got any ideas on what to check? I'm at a loss and may have to resort to taking this to a dealer to get serviced.
