Vibration
Hi all. Bought a 2015 ec250 bout a month ago. It vibrates a lot. My mate got a 300 same year and it doesn't
vibrate half as much. Changedd the o rings in the exhaust and the springs. Done bolt check. Changed rear wheel bearings. Anything I can check? Cheers Nick |

2-stroke engine without a counter-balancer will vibrate.
Check if you both have the same handlebars, maybe he has aftermarket ones with some kind of anti-vibe collar/adaptor? Or maybe he has thick spongy bar grips and yours are worn thin? I'm new to 2-strokes, but perhaps you rev yours more and he lugs his around? Maybe this is adding less noticeable vibrations due to less rpm? |

Your crankshaft may be slightly out of alignment.

I have seen a GG where one of the head stays was loose. It was horrible...
Did you check them? Also take off your bash plate if its made from aluminum and try again... |

I would bet it would be this too. I put together a motor for a mate and carefully trued the crank after the crank stuffer bolts fell out and it was the smoothest 300 gasser I?ve ridden. I think the factory specs are a little on the wide side. I aim for less than a thou run out.
