    Question Need some 250R and YTM200 specs

    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.
    Current Machines:
    1983 Honda ATC250R
    1983 Yamaha YTM200
    1995 Kawasaki Mojave KSF250
    2004 Kawasaki KFX250 Mojave
    2005 Kawasaki KFX400 - orange
