AHHHHHH!!!! 81 GS650 Intake valve guide

[Guest]

Anyone have a source? Broke one swapping the seals. Am finding they are discontinued but can’t believe someone isn’t making them.

Thanks,
Robert

Hmmm. The 77-80 550 shares same intake valve as the 650 shafties according to some part fiches, but guides are different? How? longer,fatter?? The stem seals are the same .Maybe you could modify a 550 part

Not for the GS650. Asked them, said nope.
But thanks for the reply.

I’ll take that info and go look for one that’s close. A bit crazy that this can’t be found.

This is not a complex part, but you'll need to find someone with a lathe to make one.

You should be able to find a universal valve guide, then you'll need to take some measurements and go from there...

I don't know if 7mm ID is correct for your bike, but this is one example:
