Vintage Dirt Bike Q & A

I sent Sam a mr250 transmission to back cut as I thought that one looked best on paper for what I wanted. It was in good working order when I sent it to him used but worked fine. He did his magic on it and it looked brand new when I got it back. It shifts nice and smooth now and engages really well and dosn't slip out of third anymore. Really nice service and wasnt too expensive either. Just so no one else does it I ruined a mt 250 transmission by not installing it very well, I used a dead blow on it this time after I pressed it in with the case. I thought the case pressed it in all the way but I was wrong, gota use the dead blow too, or a shop press.
