Today I replaced the oil sight glass on my 2000 R1150GS because the old one started leaking. How is this part worth $50? That's absurd. It was made in Taiwan. It's worth $1. Hopefully I don't have to replace it again anytime soon, but if I do I'm going to be looking for some alternative. Maybe a generic sight glass from an industrial parts supplier. Has anyone been down this road? I did a lot of searching and didn't really find anything, but I'll even make something before I spend $50 on this again.
