1200 LTD master cylinders

[Long Hair]

I know this is a long shot, but I am looking for both the clutch and front brake master cylinders for a 1985 1200 LTD or a 1986 SEI.
My clutch bleeds down quickly so I can't hold it for more than 3 seconds and it starts grabbing. Both also have the sight glasses so sunburned that they are leaking. I tried to replace the one on the clutch with glass, but never got it to completely seal.

Your clutch is grabbing because the slave cylinder needs to be rebuilt because of failure to keep the dot4 fluid flushed and bled yearly since new. The slave cylinder and master cylinder are most likely full of crud now. Look under the rear of the motor and see the wetness on the clutch cover/peeling paint from the dot4 leaking.
There are rebuild kits available from K&L. Buying new master cylinders and slave cylinder is not an option you want to try to do because of cost, and most likely they are no longer available new either. Aftermarket is not an option on bikes as in automotive markets. Buying used master and slave cylinders is a crap shoot and most will need to be rebuilt also.
Start by sucking the gunk out the master cylinder. Most likely you will find it is gray to brown or even dark blood colored. Once you have the gunk out, put in a little dot4 and use a qtip to clean the master then suck that out.
There are tutorials on doing the rebuilds in the how to section at the top of the forum page.

After rereading your post and saw the leaking sight glass note....

You can still get a new slave cylinder from Honda for $95 and the master cylinders have been discontinued for your 1200 but you can use the gl1500 master cylinders which are still available new from Honda for @$70-$80 ea, they use the same internal parts as your 1200, just have a different outside look.

Slave cylinder #4 (for all the 1200 and 1500 are the same.)
