Expensive little buggers ! LOLYup, that exactly what I used te replace my sight glass when i rebuilt my M/C. Per instructions that come with the glass, you use RTV silicon to seal and install it. I used the Ultra black stuff myself. Has been holding up fine so far.
yeah, it is kind of expensive for that tiny piece of glass, but it's still far cheaper then paying for a whole new master cylinder.Expensive little buggers ! LOL
that's what I did also, two years ago...all is good.My sight glass is still like new after 14 years, because I keep a piece of foil tape over it. It's the sun that ruins them. They are plastic not glass. I had the sight glass fall apart on one bike, didn't even try to replace it. I put a piece of foil tape on the outside, filled the hole with JB Weld from inside, let it harden, removed the tape, ground it down smooth, and repainted the mastercylinder. It lasted for over 3 years, and was still holding good when I sold the bike.
