Uggggghh, if this hadn't stopped me, I could have put the motor in the frame tonight! Actually, I probably could go ahead and bolt it in the frame, but I'll have to wait and see what comes of this whole thing by tomorrow.

The parts drawing is NOT very clear on how this '83 powervalve hooks up, or at least not to me! I've just got to get the parts mated up on the powervalve itself in the cylinder, and I'm off and running...............or doing a happy dance!

I guess if nobody can show me a better illustration, I'm going to have to hit the local mechanic tomorrow and see if he can help me out in a short time. I just have this feeling he won't know, and will have to buy a manual............................ meaning days and not hours to get it fixed.

In the first photo, there's the items 22, 24, 25, 26 that mate up with the 2nd photo items in the box marked YZ250K. I played around doing this and that, but nothing seemed to look like it was right.:confused:
