I bought a clarke 3.1 gallon tank for my 02 YZ250 and had some minor difficulties putting it on. The holes on the tank and the holes on the two brackets that hold the tank to the frame did not line up and required re-drilling, the feul petcock leaked very bad until the two screws were torqued twice as tight as they were on the stock tank, and the radiator shrouds dont fit right, they stick out 1/2 an inch on top close to where they bolt to the tank. Has anyone had these problems with a clarke tank, I have done some research and they are supposed to be perfect compared to the IMS. Does anyone have any suggestions? Thanks
