Hey Everyone.

My Buddie (Jason, Dave you will freak out) Just bought a YFZ 450. All Stock.

I told him the first thing to do was change the timing.

I thought this was a big job and I thought there was a thread on how to do this but I can not find it.

Wht special steps is there. Also I heard you advance the exhault tooth 1. Buy my dad thought you retarted it.

Do you retart or advnace the timing? Intake or Exhaulst?
What steps is there? I know how to take the head and stuf off and how to adjust it, But I have never done it on a YFZ.

Also wht kind of jetting you do when you take the baffles out of the exhaulst? I live aournd 750 Feet above sea level.

Thanks

I found the Article I was looking for in Dirt Wheel Mag.

It is the January 06 Issue Page 222.

Easy to follow steps.
