So I'll explain what's happening. Sat on the duel carriageway on the way to work earlier between 70-80 and its lurching as if I'm driving thru tar for a second or two then goes again then slows again.

This is while the throttle is held steady and the speedo isn't really showing any difference worth noting. If you where viewing me you probably wouldn't notice it unless you where on the bike itself. I've noticed it for a couple of weeks now but it's getting worst.

Any ideas what it could be? Always starts on the button? Even if left a week it'll start easy. Was serviced maybe 1000 miles ago I always keep it serviced

Hope you can all help. Cheers guys
