XS650 Addict
After the bike was sitting for many years I found the original gas cap gasket was disintegrating so I bought a new one from Mike's. I still haven't gotten the bike running but just from opening & closing the cap for de-rusting it began to come apart. Left pic. I found a replacement gas cap on ebay that was supposed to fit my bike ('80 xs650SG) but it didn't. Thought maybe I could just use the gasket but that didn't work either. Pic 2. Then I ordered a gasket from XS650Direct. Pic 3. It fits and closes but leaks. I found a washer of the right size to fit inside the part that holds the gasket. I drilled holes in the washer to match the holes in the spacer. The idea being to add just a little more space, moving the gasket a tad farther from the base of the cap to make a tighter seal. This slowed the leak and I don't know but that it might be OK for normal use but when I turned the tank upside down there was still leakage. Not nearly as much as before but still leaking.
All this to avoid paying $40 to partzilla for what they claim is an OEM part. Sure, maybe it is but isn't it likely to have hardened over time? Also, I'm somewhat concerned that the whole setup seems to put a lot of pressure on the gasket. Why else did the one from Mike's fail? Why wouldn't an OEM part do the same?
Say I bite the bullet and get the part from Partzilla. What do I get since the gasket is shown as unavailable for my 1980 model. For 1981 the diagram shows part #2MO-25641-00-00. Will that work & should I buy it? I sure wouldn't want to spend the $40 after all this and have it still leak.
