I’ve always dry-seated bearing shells.
Although I don’t clean off with any solvent or anything- just wipe off any oil that may be on there.

Pistons in the cylinder. Getting ready to pop the cylinder on the top case- but of course found I must not have ordered the two ‘O’ rings that go on the oil feed pins between case and cylinder. I’ll look again and make sure, but also asking around for dimensions of the ‘O’rings. I have the old ones,...

Pistons/pins/rings/rods all matched and together. Installed main bearings, popped the crank in and bottom case, measured all the main clearances. All great. Then take it back apart, get ready to install pistons in the cylinder- then cylinder to top case. Drop crank it and connect all the rods (I mea...

Doing some weight checking- try to get them as even as possible.

The old scale is from the Dental Lab, weights are in Troy Pennyweight...

Cleaned up cylinder, threads on case studs, weighed pistons and checked ring end gaps. Pistons are within 1/2 Pennyweight (12 grains ...

I got busy with a customer bike and my Electric Motion mods. yes, you offered seat cutter- I have one, if it does not work I will certainly take you up on it. I’m waiting on some parts I ordered, so I think I will start putting the bottom end together. I’ll start with pistons in the cylinder, then o...

I certainly appreciate all these posts. Including mentioning when you do it out of order, or find unforeseen issues.
Great stuff.

I’ve been working on cleaning up the head/valves etc. Coming along well.
I think I’ll get the head all together before doing the bottom end.

Also doing a few additions on the Electric-Motion Escape R (electric trials bike) and starting to work on a customer KLX250.

Interesting conversion. I’d probably put it back to origianl if I had it.
I’ve seen a few for sale now and then, nice machine.

I’ve always wanted the 180 Volcano mini. I’m not sure why

Yes, valve stems are quite small. I just saw an adapter for many grinders that will work with small valves. But first I’ll see if I really need to grind them. They look in really good condition. I have not done anything lately on it- other bikes came in to work on and I did some maintenance/mods on ...
