Anyone come across this problem before? I can't seem to roll the throttle smoothly without the bike lurching. I can't ride the bike smoothly at low speeds (engine at 2000 to 3000 rpm). When I slightly roll from the closed throttle position the engine and bike surges forward, it dosen't matter how slowly I roll the grip, it surges. It is really bad in 2nd gear, especially going around curves and in traffic, the bike is constantly hopping back and forth as I roll the grip. This always happens while in gear.
I've checked the throttle cable free play, it's good. Any comments would be greatly appreciated.
