Ok, so now the bike is really out of time. Apparently when I was yz timing the bike before, the intake cam jumped too. What i need to know now is what is the easiest way to retime a wr 400. Forget the yz time stuff, i just want it to run again. So now i am starting from scratch i am afraid. According to the book, the punch marks should line up with the top of the head when the motor is at TDC. I should also have 13 pins between the two 12 oclock marks. Correct? In the picture in the shop manual, it is only showing 12 pins and it is for a wr400. I remember seeing that it was 13 on here. Will the marks line up exactly horizontal on the head or will they be a little off. Man did i screw this up.
