yami manual says to install head gasket dry to clean surfaces
whoever had the head off last time seemed to have used some kind of sealer:ugh2:
does anyone use a gasket sealer compound?
thanks!

Install it dry the gasket is resin impregnated and once you heat it up it activates the resin in the gasket.

pull off the airbox, loosen lord mounts to pipe, pull pipe away.
Loosed head nuts in order, a little at a time to avoid warpage
I tapped the head lightly with a rubber mallet per the manual
No luck
So I put the plugs back in had tight and bumped the starter. Popped the head right off

the stuff on the head was not sealer, it was from the oem head gasket.
unfortunately I could not get off this lord mount
needlenose vise grips spin the bottom waser but it doesnt unscrew
the lower lord mount on the pipe was about shot too:bad3:
so I cannot use the new head, its 75 degrees and I am bumming

so I put down the camera, cleaned up the mating surfaces of the old head with carb cleaner and elbow grease.
I did not want to scratch the mating surfaces so I used my fingernail to get the goop off.
once totally clean, I reinstalled the old head with new head gasket
torque the head bolts to 11 then 22 ft lbs as instructed, in order, reattached the pipe etc and went riding.:woot:

except now I need another head gasket and two lord mounts
time to post a WTB thread, I guess

the moral of the story- have spare consumables like lord mounts ready

and dont tear into a ski when it is 75 and sunny
still got to ride for two hours before sunset. :Banane13:

TYVM - very helpful posts. I need to order my gaskets and get busy.
I checked compression on mine today and had @170 in each. Does this mean the head has been milled or something? This is my first season with skis but I thought I had read that high compression can equal high maintenance. Not sure what if anything to do about that. Probably will replace the gasket and run it till it quits.

170 on 81mm pistons probably means the head has been milled. 170 is a safe compression and will not decrease the life of the engine. You will enjoy better bottom end, just be sure and run 93 octane fuel. Maybe 89 but why chance it..

Heat the boss on the head up a with a propane torch, just not too hot to destroy the lord mount. This might get it to break loose and save buying a new one..
