I am experimenting with some sight glass and I think I got the right dimensions. So far the opening is about 14mm and I tried to see which sight glasses will work and not.
I will post some pictures 2morrow so people can critique and get feedback. I installed it in my gz250 and so far there is no leaks for the past 2 months.
I got 2 extra ones, so if you really, really, and I mean REALLY need a sight glass, and you don't have a working front brake, then just pm me with your address and I will sent one for free. just post your thoughts and tell me if it leaks oil or not.
This is experimental, so i assume no responsibilities. Its just a sight glass, 2 o-rings, and a thin nut.
sorry, i only got 2 and its for the people who want to try it out.
