Would anyone be interested in the purchasing of replacement sight glasses for the Brake & Clutch master cylinders?
I know that there are some of these that have discolored or leaked in these older bikes.
I have just finished replacing both of my sight glasses with a mineral glass watch crystal.
I wanted to powder coat my master cylinders. To do this, I needed to remove the sight glass as it would not take the heat of the curing process. In doing so, I destroyed the sight.
I have replaced both of these now with the watch crystal. I used quick setting jewelers 2 part epoxy to bond into housing.
I had to buy 3 crystals & the epoxy to meet suppliers minimum order. I have had the extra crystal soaking in brake fluid for several days now. It shows no signs of discoloration.
If I could do a bulk purchase, it would cost $12.00 for two crystals, including shipping to you.
If you wanted, I could also get the two part epoxy for another $5.00.
I know these work on 1st gen bikes, but I am not sure about 2nd gens.
The crystal I used is 17.5 mm dia., & 2mm thick.
1st picture is of old sight removed & O ring that is under it.
2nd picture is of installed crystal.
Let me know if interested.
