Inherited a problem this weekend. The bike's been perfect up till we got the cambelts changed now it seems that if you open the throttle past 50% there's no power at all (as good as putting on the brakes). Throttle back down to about half way and the power comes back. Also seems to just cut out every now and then. The cutting out hasn't happened whilst stationary, but when you're doing 30/40/50 mph it just stalls. (pull clutch and start with button) Dash still lit, speedo still reading, just flat out stalls. Anyone have any ideas? It could be coincidence that the belts were done and this problem's arisen, but I'm not sure.
