I'm rebuilding the top end on an '05 Predator. Can somebody give me the torque specs for the cylinder/cylinder head bolts and the cam cap bolts? Also, what is recommended valve clearance? Thanks.

I have the 03 predator service manual, but they wouldn't be the same would they?

I believe it's the same motor, so specs should be the same.

just an FYI for those torque specs. Just from them saying turn the bolt 90 degrees and then 90 degrees again sounds as though they may be torque to yield bolts. which means if they are they are only good for one use. TTY bolts actually stretch to make their most clamping force and do not shirnk back when loosened. Buy new head bolts if you havnt already or atleast check with someone to see if they are TTY. Dont reuse a TTY bolt.
