If I remember right someone had cast new cush drive rubbers for their bike out of polyurethane. Think it might have been Irk but my memory isn't good.
I'm not sure, but don't ask Brodie.

Way to many build and half done projects to list here.
Sr250, Gs750, Z50A, XV1100, A10, Z160A.

Yessir, that was me.  I've cast from an original, and I've cast them into the hub to convert a non-cush hub to cush.  I can make a mold for you, John.  Or I can cast you a set.  I used 70A urethane, but I imagine 90A would work too.

What would you need to cast me a set Irk? The only onceís I have at the moment are the worn out one so dimensions are shot.

Easiest thing would be a set of OG.  Usually they're 5 or 6 identical units, so just one if that is the case.  Having the sprocket carrier will help to test fitment. The whole wheel would be great, but I think the carrier should do.  I can make a good set from a bad set by casting the OG pieces in wax and sculpting them back to the right shape and dimension.

I saw a used set for cheap on fleabay so I snatched them up. We will see what kind of shape they are in when they get here. Hopefully good enough for now and Iíll get the old ones down to you.

Well with a mix of the two sets of Cush drive rubbers most of the slop disappeared. Thatíll be good enough for the moment. Got the headlight on. Bout to order some more parts.

Work has been taking it out of me lately so I havenít done much work on the bike. Seeing Irk finish his awesome chop and Kanticoy start on his inspires me to get moving on this again though.

I sought outside help on the front end. Mr. E came over Sunday and took a look at things for me. We came up with a plan that I think will work and he is kindly doing a little machine work for me. Hopefully this will get me moving on it again.

Just saw this, and Iím in!
I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.

So Mr. E took my steering stem nut and a CX500 triple tree and modified them to fit. I started putting the front end back together and noticed what you see in the picture. The nut actually runs out of threads before it can tighten on the bearing races. Someone was riding it around with the front end all sloppy like that. So next up is that E is gonna turn me a spacer to take up that gap.
