Had a need for a rear Master cylinder for my 83 1100 rebuilt the old one still leaked from piston,could not find a replacement anywhere until I did BUT eBay guy sends me one that fits the bike but is different!! 1st is my 83 has hard lines with a fitting that has fine threads, the eBay part has rubber lines with banjo bolt wide threads so I do have options to use this eBay part. Problem is don't know what year it's from so ordering a kit to rebuild it is well isn't gonna happen without some help from you guys! The one that was on my bike had hard lines and a 5/8 bore this eBay item had the rubber line with a 14 mil bore. Anybody got a clue must be from like a 80 81 or 82 I'm thinking cause the 5/8 bore would seem to be an upgrade as well as the hard lines! Appreciate any input guys been banging heads with this for a month trying to get these brakes working!! THANKS AND RIDE SAFE..

80 81 front caliper piston 45107-415-006
82 front caliper piston 45107-ma3-006
80 81 rear caliper piston 45107-415-006
82 rear caliper piston 45107-ma3-006

83 front caliper piston 45107-mb9-781
83 rear caliper piston 43107-ma7-006

google the part #'s and find the specs on the different piston sizes.
These numbers came out of the parts manuals.

Hope this helps. I just re read your post. I'm on the wrong track
