I've noticed my engine has been a little harder to start and before it warms up it's runnin a little rough and missin. missin while ridin, especially at constant throttle and feels like power is being robbed so to speak. When it misses the air pod raises up kinda like a backfire or somethin i'm guessin. Also some starts have a few moments where something sounds like it's stuck; got a clickin noise to it. I've ran a tank of premium gas and seafoam through it but no change....... :thinking: I might try changing the spark plugs, but that shouldn't be the problem.... any help?
