65mm is what I was told they used.

They have 65 and 65.5 stock replacement pistons for the 350 on their site here:

I just pinged Bill again to see if there are any updates on the 358 engine they were building. I'll see if I can post details when I get them.

Bore-tech also has full 350 kits for these motors (CB77 at least) - including pistons, cylinder sleeves, etc.

I e-mailed to ask about the pistons and was told they were the same as the CB350 pistons they sell, but he was to send me more info about the build and I have yet to receive that.

@nc_rider - the rims are marked Takasago - I think they're pretty common on eBay these days. The guy I got this from had bought a bunch of stuff on eBay - rims, pistons, ignition points - kinda haphazard, but I'm sure they'll come in handy.

I suppose custom would work well, as it's probably a custom dry clutch as well. Also, replacing the cam-chain ...

This is a thread to document the teardown of a really corroded CB77 engine. If I get it all apart, and maybe find a donor engine, there will be a thread on the rebuild. Basically, a cautionary tale of how bad it can get - I know there are worse, but this one is mine ;-) Here goes. As I got it: http:...

Good call on the grease gun. I had seen that reference elsewhere, but couldn't figure out a clean way to do it. Most of the time they call for making a zerk adapter from and old sparkplug, and I think that would work,but you'd have to use the top crankcase cover to hold everything together after you...
