the bike had water in fuel. tank drained-flushed-checked fuel pump, refilled with clean gas. everything ok! but now it cranks for maybe a minute till it finally runs by itself. once it has been started it will fire on the second or third rev like it should. but cold starts take a lot of cranking ! any advice would be greatly appreciated ! i have replaced primary fuel line, no difference. maybe injectors have trapped air - need to be bled ? primed ?
