Tyre Valve

[Garryzorro]

Hi
Does anyone know the tyre valve size i need for my 1980 GS850GT, also can i use one of the new tool kits you can buy online to fit the new valve, the kit allows you to fit the tyre valve and you don't have to remove the tyre.
help

I've not seen nor heard of this yet, hard to imagine putting it in from the outside, seems the part broke off and rolling around inside the tire would throw it way out of balance... Let me search this out a little bit... Oh yeah, before I forget, WELCOME

Interesting - Got a pic of the kit or a link to check it out?

I should think you have a tube type no? At least on the front (from memory the 80G’s had tubeless on the rear only).
I don’t see how you can fit from the outside either…

Neither is a replacement for taking the tyre off and cleaning the valve seat, anyway.
The first one looks good for an emergency replacement at the side of the road, and I'd have one in my toolkit for sure, if I remember to get one.
The second one is more car oriented and lost all cred with me when he used dish soap as a lube - dish soap contains a lot of salt, you can imagine what that does to your rim.

Lost all cred with you, then use whatever you wish, plenty of stuff out there to use, plus road are full of salt in Ireland.

Both mine are tubeless, to tell the truth i never knew that some GS 850G had a tubeless at rear and a tube up front.

I believe the fronts only became tubeless in 82. Some people convert (although you still don’t have a tyre retaining bump but it seems to work if you use the right stepped cutter to flatten the area around the hole).
