They won't shoot out. I would take the wheel off. Then do the shocks one at a time. If you undo the bolts. The tube should still be a tight fit. You might have to twist it, while sliding it at the same time.

Once I loosened everything the opposite happened; I got the axle off the wheel and the shock fell on the floor. When I put it back I found there's a circlip that stops the tubes from moving any further. So other than for FYI this was a waste of time. Technically I could dig the circlip out and move the tubes as far as I wanted. But doing so requires removing more items for work space. So maybe I'll put it all back together and live with it for now.

After lunch I decided to "GIT er DONE, as my running buddies would say. So I dismantled enough to see the tube ends, Still looked like a circlip. Usually a hammer and chisel knocks them out. After pounding for a while and not seeing progress I went looking for flashlights. With three lights I could see that it's not a circlip. Instead it's a raised edge like a shoulder. Solid metal. I could have ground it away with a Dremel but couldn't find it. So after dinner I'll try re-assembling everything and hopefully not forger and screws or bolts. No guarantees.

My Yamaha forks have the circlips in the top. But right at the top. Nothing to stop you mounting them lower. You can still slide them through. I don't really get what you are saying. If there is a ring. How did they slide through? If they fell through, why can't you push them through higher?

www.youtube.com/watch?v=yWrSLBBWEjwCheck this out for seeing the inner workings of the forks and how to disassemble. You could cut a bit off the springs but make 100% sure they are the same length afterwards or find shorter ones w/ the same # of coils or a few less, you might also have to use a different amount of oil, you could take a dremel to the ridge but i'd worry that they help keep the shock from pushing through the triple tree when you hit big bumps.

The tubes enter the triple tree from the bottom. There's no other way to assemble. I thought what stopped them was a circlip at the top. But no, it's actually a small ridge at the top of the mounts. If I were to grind the ridge off then the tubes could slide any length I wanted. There are two 12mm bolts in the triple tree atop each tube so I think these could prevent them shifting at bumps. But grinding them off means 'no way back' so I'll hold off for now. I understand the other method of lowering involves changing the internal springs in each tube. But the videos show a vise needed and mine is still at the bottom of a pile of tools out in the yard. We ordered a pre-fab garage. It's been delivered and they're still getting it wired. I also need to build a work table to mount the vise to.

Ok I understand now. It was worth a try.

I hate to keep beating a dead horse but...I finally found my reading/surgery glasses and can focus much better. The photo shows where the shock connects to the triple tree: Two 12mm bolts plus a serrated seat. The shock abuts a shoulder maybe 2mm. If I grind off the shoulder and move the shock half an inch vertically will the two 12mm bolts be enough to hold the shock in place? Anything else I could do to keep it in place? Special washers? Thread treatment?
TIA,

Hard at it. I can't see the images til they're posted. I disassembled enough hopefully to be able to grind the ridge off the triple tree so I Can shorten the shocks a bit. I hope I can get everything back together. It's deja vu; I tore over a dozen VW bugs apart for restoration and always hit a point where I didn't think I'd be able to put them back together. Often I found if I started off wrong I wouldn't know it till every thing was reassembled. If it didn't run I knew I'd screwed something up and have to tear it all apart again to re-start the assembly correctly. The scooter is only a little less complicated. kevino

Took a lot of coaxing--with a hammer--but one shock is done. For a VW I would have put the wrist pins in the freezer overnight and heated the connecting rods in the toaster oven for an hour. I suppose I could put the shocks in the freezer but no easy way to heat the triple tree. kevino

It's better if it's a snug fit. All the forks I have done have needed a firm twist. Just make sure it's smooth otherwise it will scratch the leg.

Kevino, If the height turns out to be perfect for you and you really like it, but would like to be certain it will never slip lower, you can have someone weld a cap over the top of the shock to the triple tree.

Thanks but in case I want to sell it in the future I can't do anything that can't be un-done. I got the second tube ground but I'm clueless how to but it back together. I'll figger it out but I wish I'd taken pictures along the way.
