Thought it was the battery (that is why that bike has that badass battery, Kev) but turned out to just be the valves too tight...
If you look close when rotating the engine its easy to see the overlap portion of the cam. If you can't tell the difference pull the plug and locator pin and put it on the right tdc. its just takes longer.
