I'll preface this with im a late 20s professional practice rider. Headphones in vibing to good music just flowing along before a burst of speed to send a triple and then slowing back down cause my arms are now pumped up. This riding doesn't justify the money i put into my bikes but i love the bike-work side of the hobby (dialing in a setup) so it happens.
Rode 4 strokes but got my first 2 stroke brand new in 2018. YZ250 that got quickly tore down into a ported&milled race gas burner that kids on 50s would say looked cool while their dads rolled their eyes.
Later picked up a clapped 2001 RM125 for the girlfriend at the time. The relationship didnt work out but the bike was mint when finished.
So when a friend had a 2002 CR250r for sale i had to jump on it. It looked rough around the edges but there were clues that most of its wear and tear was age not hours so it was a good base to start with.
At the same time a friend picked up a 2000 CR250r and so both bikes were torn down.
Engine was pulled to be vapor blasted and rebuilt. Ported&milled for C12. Insides turned out to really clean but still got a new cylinder my mechanic had on hand still in the box along with a complete Recluse clutch kit. Pic when the engine first got pulled
Got it mocked up after the frame and other parts came back from vapor blast. Decided i didnt like the look of the restyle kit with oem looking graphics. Too many of them done like that. So change of plans going with black 02-07 plastics with the restyle front and graphics inspired from Cole Seely's red-bull imagination bike.
Right now i have the suspension and engine back from being fully built. Running a a full FMF exhaust, Boyesen Reeds with Lectron carb. Next is the long process of careful reassembly with correct hardware. Plus all the little details like chain&sprockets, new brakes, lines, levers, and such. Should be done in the next 2 weeks or so.

Very happy with his work.
The Shop
I used to do it with a soft bristle wire brush, they came out decent but it was a crazy amount of time and effort and you couldn’t get in little crevices like around the front sprocket. Are they able to do it with the bottom end assembled?
They blasted the engine complete and it came out like new.
Just make sure you blank off all inlets and outlets well.
All that's left is: mount the new tires, brake-rotors&pads, rotor guard, brake pedal return spring, and install my vapor blasted and rebuilt PWK long body carburetor. The TMX had to go.
I met my Goal: buy and rebuild a third gen CR250R for less than the $8,400 MSRP of a brand new KTM 250sx 2- stroke
