Wr timing question with pictures!! help?

3 posts in this topic

Due to being a partial road bike, partial trails, i decided I wanted to try the WR cam settings. I had pulled the valve cover when i first got the bike to check the valve lash, and noticed 12 pins between the cam gears so i knew I had yz timing. While the bike is quite fast when you go WOT, I want to try having some low end, after riding my brother's xr 650 I realized how much i DID NOT have! haha

anyhow, Just wanted to check with you guys before i button it up.

Here is where the timing mark was, next to the "H" and with my finger holding in on the timing chain tight, my cam gears were like this: Right side(intake) cam even with the top surface, Left side(exhaust) looks one tooth out.

SO> To convert to WR timing, I just remove the exhaust cam and move it one notch to the left so both OUTER dots are even with the valve cover surface? THANKS!

Your intake cam looks like it is not lined up either. Can you post a pic from the other side showing the lobes. Yes, from yz timing advance it one tooth. Consider the hot cams to get auto decomp.

Granted I'm a newbie, but I just went through this. First reply was on the money. You get a much better indication from the lobes. And do the roll back to take the slack out; don't ask.
