I seem to be missing the tank pad on my wife's '82 GS850G. I noticed one of coils has wear marks on it and it appears the gas tank has been rubbing on it, not good.
What do you expect when you buy a 30 year-old bike? I checked the parts fische and it appears I'm missing the tank pad, part #44541-49401. After checking a few sites, it appears it is "disco". It is a common part for '82 and '83 850s, and '82-'84 1100 shafties. Judging by the ghost marks on the tank, it measures aprox. 6x10 mm, and it looks like there's some nubs on it that pull through a plate on the frame. These said nubs are aprox. 5 mm apart. Does anybody out there have one or at the very least can you give me thickness measurement so I can make something that will work?
