1/4/2021 10:19am I've heard that is fairly easy to shed 10 lbs on the 1980-81 YZ250's by replacing steel nuts and bolts, wheel spacers, handlebars, and kick starter.

10/21/2019 1:02pm 1980 YZ250 was in perfect running condition before storing it for 8 years. I now seem to have a leak where the center cases join. I have no compression I thought the ringlands where gummed up so I put a brand new piston and ring in there all within spec.... Still no compression. This crankcase leak would cause loss of...
