in the manual for a 1998 mxz 670 it says to torque all of the head bolts down to 21 foot pounds except the center bolt that is closest to the thermostat housing. for this 1 it says 90 inchpounds. is this a misprint in the manual or is there a reason for it[?]
thanks

????????????
I've never seen or heard of that, it don't make sence to have one bolt so loose than the other eleven bolts. I always go 21 ft. lbs. Are you sure the coolant temp sensor is to be at 90 inch lbs.
