yfz450 how to install a piston

Yamaha

does anyone have ideas on how to install a piston and torque the head bolts (the specs)

clock the ring set the dot tawrds the exhaust and You torque them to 14 ft lbs, then 2 steps of 90 degree turns. They are torque to yield bolts and generally should be replaced everytime you take them apart.

I was poking around on the internet the other day and found the factory service manual for free in pdf format. I don't remember the web site but I found it by putting " 2006 YFZ 450 service manual " in the search engine. It has been invaluable when I don't know how something goes together or comes apart.
