August 1, 20206 yr I'm finding the bike will "surge" after I cut the throttle. Generally just a "pop" or two, but it's enough to make the bike lurch forward just a bit. I don't think it's back fire, it's as if I just gave it a little throttle, when I didn't. Any ideas? Thanks
August 4, 20206 yr Dellorto? Have you cleaned the carb, and set it up correctly, is the air filter in good condition, do you change the plug very often?
