Ok, been through this twice now with different vendors, cannot seem to get a seat cover to fit my '80 CB750 Custom. Great bike, love it but the seat is trashed. Where can I go to get the right cover? The last one I got from ebay (i know) seemed to look good out of the box, but seems to be two inches short and one inch narrow to fit, and I have been working it for two days. At this point I don't really care what it costs, but I don't want to miss the rest of the season and fart around with bad parts.
Take it to a couple of upholstery shops and get an estimate. You may be surprised that it's not much more for them to do the complete job than it is for you to replace the cover yourself.
