Rebuilding the forks on my '78, using original equipment xs650 springs (hoping for a bit stiffer fork, and will go up to 15w oil). Cut pvc tubing to act as spacers, but noticed at the hardware store, copper tubing, precut, used as plumbing joints, pretty much EXACTLY the right size. Any problem with using copper spacers in the tubes? Thanks guys.

Hi wheels, copper tube might be too soft and deform under load, thats something i havent tried though. I have used a flat washer and an old valve spring as a preload device, it works reasonably well to remove excess static sag, just cut the spring to whatever length you want. cheers franky b.

Progressive says to cut pieces of plastic pipe for preload, I can't imagine copper would be much softer than that but I know what you mean.
I found the 1/2" recommended to be too little and went back to the stock spacers.

Thanks guys. I went with the copper tubing, with the 1/2" pvc inserted into it, cut flush at both ends. The pvc fit perfectly into the copper, and built it out to fit the fork tube with little play. I too was worried about the 1/2" binding, as the fit was bad. Got the front end together, was cleaning up and found the spring cap/washer from one of the forks though. Must have popped off on one of my attempts to compress the innards and get the top cap threaded. I'm pretty sure it was the right fork, so I'll start there. I'll post some pics soon, cause along with the fork rebuild, I restored the entire front end (including splurging on a new oem front fender and headlight bucket  ). The originals were just ok. Now she gleams! Gary Hopwheels |
