shim club

Does anyone know if the Shim Club is still in operation? I need (2) 2.60 shims for my '82 1100G and am hoping to avoid the online prices.

Online prices aren't crazy these days. I bought a few 25mm's from 4into1 for $8 each. Not bad if you know the sizes and only need a few. Also don't recall if that is the Suzi size or if it was for a different project.

Thanks. I'll look into 4into1. The best price I could find so far has been $13 each and $15 for postage.

Z1 has shims for $4.83 each.

I quite likely have some 2.60's. I'll check later and let you know Willie.

Pm me exactly what shims you need and what exact size shims of yours you would like to exchange. I have a pretty good collection, worst case I don't have em.

[Nessism]

If Gabriel doesn't cover you I've got some 2.60's. It's best to stock up and plan your next adjustment while gathering shims. Take an inventory and get some smaller sizes than what you have now.

Thanks guys. Thanks a LOT! Storm responded to my PM earlier this evening and offered to mail me what I need.
Thanks again and have a very merry Christmas!

Yeah hmm I sent a line out to Ray a while back to see if he had a 2.55, haven't heard. I'll probably just pick up a handful of sizes at Z1 before spring.

Two questions, do these valves ever get to the point of no more necessary adjusting?
If so, what mileage might that be?

No, never. The clearance reduces with mileage as the valve sinks into the head.

Do the 8 valve GS heads have hardened valve seats?

Yes, but there is still wear.

A well taken care of big GS bike will run 100k miles or more. Problem is, many don't take care of things like valve adjustment and when the valves sink, the clearance goes to zero, and when that happens the valves hang open and burn. Valve seats can overheat and crack too.

The last time I reconditioned the head of the S I had the seats recut back to the original angles also had the engineering shop 'top' the valve stems of 4 new valves to bring the shim gaps back to the thicker shim end.

Yes, that's the standard process.

Big Jay from APE said that when the KZ1000 police heads come in for service they tip the valves to bring them back to OEM height. Sometimes, he said, that results in the valve keepers sticking up above the end of the valve, and when that occurs, they trim back the keepers too. Good fun.

Hi. I have 6 or 7 shims in the 2.7 to 2.9 range that I likely will never use. Happy to donate them
