So after my new Xl250s test ride, theres a few things I have to fix. The valvecover was leaking, so I had it off to replace the seal and decided to see if I could move the rocker arm, just for laughs. Couldnt move it, there is no valve clearance on exhaust or intake (which is weird cause you couldnt tell from riding it) What should the clearance be? I remember from my 79 XL125 its something like .002 or .003, but I assume the older 250 is different? Its the 4 valve head, if it makes any difference. Thanks for the help!
