My overflow would fill and not dispense back to the radiator but would stay at a minimal level till i got on the bike and the gas then it would leak and overflow....

never put lock titght on the head and cylinder bolts. NEVER
you can put lock tight on the head thought just not in the threads.
the way i do mine is after initial torque is i take a paint pen and draw a line on the bolt head all the way on to the head surface. doing this will allow you to see if the bolts are turning after some run time.
this is what i do:
first torque run engine for 20-25 hours then
retorque and run engine for another 20-25
then the last torque, then check at the 50 hours mark
on the raptor the left side head and cylinder bolts always losen up. i suggest you change the head gasket every year and retorque the cylinder bolts once a year also.
if having problems with cylinder bolts on the left side getting loose check for cracks in the left aft bolt for the cylinder.

Well, I finally got around to goin home and tightening those head bolts and VOALA!! No more coolent leak! I was so excited when I found out! Thanks a bunch guys for your help!
The second headbolt next to the timing chain was almost a full turn loose! I thought it was stripped out when I tried to turn it! The other one next to the timing chain was also loose but not nearly as much. I was crossin my fingers hopin I didn't blow the damn gasket! Thanks agian!
