Vise-Grips didn't work.

I'm not experiencing any weeping at all, but after reading this thread a few months ago, I thought it would be a good idea to re-torque the head.

If it ain't broke.... :D

Did you just happen to be taking the valve cover off the bike and decided to give it a go?   :D

When I retorqued my head, the valve cap bolts were also on super tight.  While I did not snap a bit, I definitely twisted it.  It could be related to the bolts sticking or the heat cycling of the engine.  

The retorquingworked for me.

One note when retorquing; Follow the bolt removal sequence outlined in the manual.  When removing the first bolt, take it completely out, inspect and oil the threads, then retorque it to about 1/2 of the first stage torque value.  THEN move on to the next bolt and repeat.  This way you always keep some clamping force on the head so you don't have to worry about your liners.  Then proceed in the proper order and torque your head bolts in stages:

Manual:       15 ft*lb, 20 ft*lb, 90 deg
My Engine:  20 ft*lb, 25 ft*lb, 90 deg

Be well!

Kurgan,

Wow that bike is clean, I've spent hours on my '01 and still haven't come close to that.

Simple Green and some elbow grease. The stuff works wonders on everything from bug guts to road tar. Just be sure to wash it off quickly, as I hear it can leave permanent stains on exposed aluminum. I do a final rinse with Mr. Clean Auto Car Wash... to ensure there's no dried water droplets.  :lol:
