I have an IMS 3.2 gallon tank on my 08 CRF450X and the strainer assembly that goes into the tank at the bottom is fouling the head cover. This has resulted in the head cover nearly being worn right through. The tank itself also touches the head cover slightly causing additional errosion. By inserting some pipe insulation between the tank and the frame I have raised the tank a little but as the foam compresses the fouling starts again. My thought was that this could be eliminated by installing the screen assembly from the R version of the bike. This is shorter as it has no reserve. Does anyone know if they are interchangable between the X and the R. The tanks are different but maybe the fitment is the same. Thanks in advance for any help in this matter as it looks like I am already down the cost of a new headcover.
