i own a 2005 c50t as to date every thing is still stock. I am experiencing a fuel knock as the bike warms up of course the warmer the bike the worse the knock. Mostly on acceleration and again the harder you accelerate the worse it gets. Has any one else had this problem? The bike also seems to run a bit rich not sure if that can cause it or not. And of course my worthless dealer has the same answer as he does for every thing else (that is common for that bike) B.S. Any way i have tried different fuels it does not seem to make a difference.
