So all this time I have owned the bike I never realized the gas cap and the paintsaver where 2 parts. When I fill up, it all came off as one unit. Well this morning, not sure why, the cap came off but the save stayed on the tank. Bing - Light came on. All this time the saver has been loose and not staying on the tank like it is suppose to. What is the best way to get the saver to tighten down to the tank so only the cap comes off?
