Sorry but I can't watch most of the videos. When you record video with your phone in a vertical orientation it makes it seem like I'm looking through a keyhole when watching it. From what I saw of the full width videos your work is quite nice.
Do not be like the cat who wanted a fish but was afraid to get his paws wet.

Finally the camshaft comes. See how sharp it is. This one caused some trouble. The factory could not meet our precision. We have to find other supplier. It took some time.

as smooth as silk after break-in

Note the water channel, the dry sleeve, and the full supported crankshaft. Crankshaft is heat treated.

Looks very nice.
What was the tool used when installing the sleeves?
Looked to be some sort of induction heater?

Thanks, Sid

It looks like a glowplug from a diesel engine. Not so custom

In the spark ignition version you showed, what size/brand are the spark plugs? Have you settled on spark ignition vs. glow ignition or plan on offering both ways?

It's Spark Ignition (LSND 1/4-32), but you can turn it into a glow ignition engine. We don't plan to offer glow ignition for now.

Latest 2 updates. Engine is still under tweaking. The piston will upgrade to 2 rings. We'll turn all 12 exhausts spit fire.

It would be nice to see this engine running under load/dyno run!

It would appear your request has been answered (sort of) :)
