Since I installed a large tank on my 2006 YZ250, I've noticed that the tank has worn through the thin OEM rubber/foam pads at the back. The OEM pads are only 1/16" or a few mm thick from the factory. I used some old inner tube, and cable-tied it place, but its not very secure or as clean as the OEM stuff. There is also a chance that with impact and vibration that the tank could push the rubber out of the way and sit on the frame. What solutions have you found? Where/what to buy online as a replacement?
