Husqvarna WR250 | Motor Breakdown

Due to the stuck crank and the sick smell of mouse piss coming from the motor I decided it was necessary to split the cases to clean and inspect everything. I was happy to find that all the internals appear to be in good condition after a good cleaning. The stuck crank seems to just have been due to dried gas/oil/mouse piss. On the bad side, I found some small gouges in the bottom of the case that need to be welded. The challenge is, the cases are magnesium.

    thats some quality repairs on the magneto/woodruff key. At least the gouges aren’t where the bearing sits.

    yea, i didn’t mention that but included the photos. The stator had fused to the crank. I touched up the crank with a file but because its hardened steel it still needs more work. I need to use my carbide burr with my air tool to get it and the stator cleaned up. Never saw this happen before.

    Cant wait to see this thing ripping around on the oval track at mid-Ohio in 2020.

    Thanks for taking over the website Adam. I guess I dropped the ball on it.
