Ever since I collected my new V back in April I've been convinced that it suffers from a noticeable engine surge at low speed - typically 15-45 mph and in gears 2/3/4. I made a point yesterday of sitting at a steady 40 mph in 3rd and 4th gears and could feel the bike pulling back and forth. Wind the bike up and give it some stick and it's as smooth as can be. The chain is correctly tensioned so that's not the issue. It's got to the point now that it's going back in to the dealers for a look-see. Possibly there's something going on with the fuel injection - I don't know. Is it possible to plug these bikes in for a diagnostics check like you would do to a car? Does anyone else suffer from similar issues or is it 'just how it is' with the V. It's kinda taking the shine off a great bike.
