1. line the motor up on TDC.
2. remove cam chain tensioner.
3. remove exhaust cam cap WATCH THE HALF MOON WASHER IT IS MAGNETICALLY ATTRACTED TO THE CRANKSHAFT!!!!!!
4. rotate the exhaust cam 1 tooth backwards, so that the timing mark that should line up with the top of the head is slightly higher than the valve cover/head mating surface.
5. put it back together and ride.
You are pretty mechanically inclined right? It's real easy to do.
As far as jetting goes???????? somewhere between 168 and 180 mains, and 45-48 pilot. NVCQ needle from the YZ 450 F
Jetting is kinda like toilet paper, you gotta go with what feels best to you.
Just make sure you put a rag in the cam chain hole. Watch out for the half circle ring that holds the cam in place.

You will also need a quality torque wrench for this operation. It is very easy to do just make sure you follow the steps in the video posted in this link from Daddogrider. Also carve out a good piece of time to do it in and DON'T rush. Make sure your bike is as clean as a whistle. I did mine with less than 5 minutes on the bike and hadn't seen the dirt yet. I finally got to take it out on our track 2 days ago and all I can say is WOW. It will lug down like our Z400 now and pull hard to the rev limiter. I now see why the dirt bike only has 4 gears. with the power produced 5 aren't needed.Originally posted by BigAl
