I picked this bike up late last summer in real rough shape. I found some recipes and a Ponca City bike check sticker that leads me to believe it was a former Am National bike for a local pro of the era, but when I picked it up it was primarily parts in a box, seized crank, trashed head/cylinder, etc. so the first step was to tear it down and start tracking down what I needed (and wanted).
This is what it looked like when I picked it up.
Here are some pics of the breakdown/cleaning process.

VHM Head cut for perfect tolerances with the Weisco GP flat top piston. Did I mention it’s also a Millennium built 144?
New stainless bolts for the entire engine from Po-Bolt
The Shop
Here is where the project currently sits while I start on the motor. I wanted to have a lot of progress to post before I started the thread, but being in “self-isolation” will do things to a man lol
I can’t say enough good about the guys at FasterUSA
Here are some details on the “blued” frame 😎
I think had the same shop apply an 80% gloss clear powder coat. I am really happy with the results!
Got a little elbow grease in last night, and started setting engine bearings today but ran out of time. Ive been removing casting lines from everything and trying to go for the billet look.
Tonight I’ll assemble and dry run the transmission. I’m waiting on a couple small retainer screws that got misplaced then I’ll be setting the crank and transmission once I know it’s all 100%
Pit Row
Got all the new bearings in where I could, and got the swingarm on for mock up. Still some cleaning left on the swingarm too. Next up is wheel bearings once all the other odds and ends show up for the wheel set.
I should have a roller here soon, and the motor shouldn’t be far away eother.
#2;The pics you are showing of the engine cases are of a case-reed engine - didn't the '04 RM250 have the reeds in the cylinder??
#2. I am not sure about the reed design on the RM250, this is a 125 build
Good news the transmission is ready! Two set screws and a washer and I’ll be able to drop the crank in.
Also got my galfer brakes on and a few shiny bits
