Hey people,

I have both of my ATCs in the shop getting checked out and I just got a call from the owner of the shop asking if I had any of the books for them, as he could not find the adjustment specs in his records.

That scares me a little to have someone who is working on them ask me that, but I've heard he does good work, and he always has a ton of customers, so I'll just hope for the best.

Anyhow, for the 250R, he asked for the "Float height adjustment"....which I assume means how high to set the float as it was bent.

For the YTM200, he wanted to know the intake and exhaust valve clearance specs.
