I have a clarke 4.7 gas tank on my 2003 honda xr650L. It was snug when i first installed it, but the bar padding has worn out a bit, resulting in the tank being a bit loose. I didnt notice until the tank started feeling more loose, but the stock rubber washer where the tank actually screws into the frame doesnt match up all that well with the clarke. The rubber washer is an odd shape, cylindrical and flaring out at the top. Im curious if anyone knows where i can find a similar washer that will tighten the clarke up properly. As it is, my petcock can actually touch the cylinder head if i wiggle it side to side. Id hate to jar the petcock out of place during a rough ride....Also during my last fillup at the gas pump, i noticed the gas filter inside the gas tank had come loose and was sitting on the bottom of the tank next to the petcock pipe spout. Guess ill have to drain the tank and see if i can put it back in place, im curious how it popped off...anyone have this happen to them? any suggestions would be appreciated before i tackle this:) hmm hopefully i wont need a new rubber washer where the petcock meets the gas tank...that thing looked so dinky and fragile when i put it on, was relieved it didnt leak.
