'85 GS700e restoration

That's the clutch pushrod. It can be pulled out if you want to get it out of the way.

Thanks Billy, so it isn't supposed to mate with anything in the crankcase? There's no discernable click when it goes in...

Sanding the fins down enough to remove the scabs won't hurt. There's plenty of fin there.

That's good news! I'll get this cleaned up then! Thanks.

It runs through to the clutch basket on the other side of the engine. Just a short piece of it comes out the chain side. It goes into the worm drive in the countershaft cover to push the rod in.

Thanks for the clarification Billy!

Another couple of questions folks:

1. What do I need to complete this rear brake assembly? Are there supposed to be boots on both sides? Does it have shims like the front brake?
2. If anything else is needed where can I source the parts?
3. Should I just try and find a used caliper?
4. Am I right in thinking it would be the same as a GS750 caliper?



Thanks!

Looks like at least one seal is missing. I think I still have my stock one if it's cheaper to pay shipping than to get parts. I'll have to see if mine is still in good shape. If so it's yours if you want it.

I would start by yanking those pistons out to see what kind of shape the bore is in. Mine were pitted to the point of having to replace them. If the bores are good you can piece together everything you need to re-build them to new.

Thank you gentlemen! I'll take jwhelan's advice and strip the caliper down to get a better picture of what state it's really in. Billy If it needs more than a few bits I'll definitely take you up on your offer!

you can take the gear position sensor off as well, check the O ring there to make sure it's OK and not cracked, watch for the little spring and little pin that is there as well you don't want to lose either of them.

I removed the sensor plugged the hole and then painted

Well that was easy!

Thanks Billy. Take 2:



Again, not perfect but we're getting somewhere...

Couldn't really see much to begin with:

But now it's a bit clearer:





Well they look pretty clean. No burrs, bumps or pitting that I can see...

The pistons:

One is clean, no marks:



The other has some nasty pitting:

What's the verdict? Can I use both these pistons and bores? Also, am I missing shims to hold the pads in place? I'm pretty sure I'm missing the rubber boot from the left hand piston. Is there anything else?

Sorry, though I'd post a cleaner picture and repeat the question:
