So I probably could post this on BS or on here, but I mentioned a couple months ago that I was gonna make some of these:
The plastic bushing, kindof a yellowish/whitish color. Originally made out of nylon or some sort of garbage plastic, wears out. When it does wear out it makes your forks wobbly and it makes your fork seals blow out shortly thereafter.
The disassembly process is pretty easy, i'll do a writeup on my blog maybe later with some better pics, but you just pull off the dust boots (no replacements for these that i know of... 1977 might have some in the handybikes stash)
there is a snap ring under the dust boot, you pop that off.
then you gotta drive/jam the seal out from its crusty hidey hole. This might take some doing. The easiest i found was to put a rod/axle/spudwrench into the axle hole and stand on it, and pull up on the toob.
once it pops out you get the assembly shown above, swap out the old bushing for a new bushing and replace the seal.
The bushings are gonna cost 30 bucks shipped. Thats what it cost me to have them made, but I only had 5 sets made. They are precision machined to much tighter tolerance for nice snug forks, and they are made out of Delrin plastic which ought to out last your moped. If people buy these, I'll do another production run with more and possibly get the price down, and probably sell through treats. If you want one of the 4 sets that are for sale PM me or email me motzingg at gmail
The seals are available here
