1989 Suzuki rm250 power valve?

I have a 1989 rm250 and I need help on how to adjust the powervalve, rebuilt it and now I'm going to start it tomaro I need to set the power valve, should I run it then adjust it or set it first, and

Find a manual and set it before you even start it.


Hint:  If I remember correctly I think the base setting is when the valve is closed (all the way down) you apply one full turn (on the adjuster that's on the left side of the cylinder) one full turn clockwise when looking at the adjuster.  That's it.
