The shift seal will be the same part as on any other 1100. I would get the part number from kawasaki.com parts diagrams and plug it into one of the OEM parts search engines. I bet they carry it. You could also try using another OEM parts seller as bikebandit.com uses their own proprietary parts numbering and not the OEM part number which makes them fairly confusing. I typically buy from
www.z1enterprises.com
and let them find the OEM part. They have access to anything bikebandit.com might.
As to why so few CSRs were made? Well by 1982, the other manufacturers had more or less caught up with Kaw and more or less passed them. The GS1100 was considered a better performer and nicer looking, the XS1100 was considered a better all around bike with higher quality and I am sure Honda must have had something to rival the CSR. The CSR was an early Japanese attempt at a cruiser and was not all that well received nor were many of the other Japanese attempts from other manufacturers. Also, Kaw had a number of different KZ1000 and KZ1100 models and some were much better sellers. They didn't make all that many as they were not moving off the sales floor. In another year or two, there was a glut of bikes with 2 and 3 year old leftovers gathering dust as the bike industry took a nose dive starting in 1983 as I recall.
