i just wanted to reassamble my WR426 Motor, but I noticed, that maybe the marks on the cam sprockets are wrong. I put the cams into the right position but as you can see on the picture the exhaust cam is directed a bit upward. Is this right? If not, how far can i turn the Cam clockwise to get a good timing? Maybe the one of the YZ ?


marks on the cam sprockets dircted wright:

I may be wrong, but your INTAKE looks like it is off by one tooth and pointing slighty up. Rotate that sucker one tooth clockwise and then it should be right. That will give you 13 pins between marks which is what you should have on the wr.

Per what I see on the First picture, you are YZ timed.
