Hi all,
I have a 1984 Honda ATC200M I am going to be rebuilding. This bike has been in my family since new, and was used on the family farm for years. I got it in the winter of 2014, got it running again and drove it around the farm for the next year or so. Ended up moving, and didnt have a place to ride or truck to haul it anywhere so it pretty much sat in the garage from early 2016-now. I got it out every couple months, drove it around the street. Put a clutch in it in the summer of 2017 because it needed one bad.
Reason for the rebuild is because it smokes and burns a fair bit of oil, also there is a ticking noise in the top end. And I have found metal shavings in the oil whenever I have changed it, so theres something in there that needs looked at. Also may end up splitting the cases and replacing the countershaft, but not sure on that yet.
First step was to check compression. Cold, not having been started since last spring compression was 135 psi. I think that's because of the oil that was in there. When I fired it up it fogged the whole neighborhood lol. But when I checked compression warm it was @ 125 psi. So not terrible, but not great.
Took it on one last ride, then yanked the motor.
Will update as I progress. Next step is to clean the crud off the engine.
