Bike surges at all speeds, not sure if its a fuel issus or a clutch issue

Surging is usually a fuel problem. To prove it, put the bike in one gear lower than the top gear. You didn't say what year or model bike you have. If it's a five speed, put the transmission in fourth gear. Do a full throttle roll-on acceleration with the transmission in that gear on a long uphill grade. If the engine RPM's climbs suddenly and drastically without the speed of the bike doing the same, it's a clutch slipping problem. More than likely, you are feeling the surge due to a lean fuel air mixture. This makes it very difficult to maintain a steady cruising speed in all gears.

Good Luck
