need help with head gasket

<< < (2/3) > >>

2001KX5:
I should of also mentioned that I had some seepage on my KX250 and just untorqued the bolts, used thread lock and re-tourqued them..........criss cross pattern taking off and putting on, diden't have an issue after that.
If its still an issue try to get a leak down test done.

Yeah I thought that was pricey for the OEM HG also. Don't forget you can get different thickness HG's also, stock thickness is probably best.

Why???  Because water is running down the side of the jug... :cry:  :cry:  :cry:

As far as the bolts coming loose..I don't think so..  All the nuts tightened down the same as far as how many treads are sticking through the nut...even if the stud was loose, the nut tightened down to spec and that should apply the required force on the head...by the way after starting the bike it leaks within 2 minutes just at idle and I did try to retorue the nuts and yes I do criss cross always (used to be an aircraft mech so I am used to it)

--- Quote from: YUNGGUNNAZ ---also note hump on gasket goes up.my oem gaskets are about 13.00.why so high out there?make sure to torque in cris-cross fashion.i do triangle patterns when possible.

Moose gaskets have no hump...if my gaskets were only $13 I would not care so much and I would go buy a handfull....


Is there anywhere I can get just the head gasket alone??

99,
  A bit basic but ,your leak can only be caused by: non-flat cylinder, non-flat head, poor gasket fit/quality, pulled cylinder stud.  You might try lapping the head with some #600 and a piece of glass for a flat surface.  I once had a cylinder stud that pulled out slowly over time. Would torque fine and run for 30 minutes before loosening off enough to blow the head gasket. Took me forever to find it!  Best check is to torque the head, run it till it leaks and then carefully check torque again. One of the studs might show up as being not as quite as tight as the others. Hope this helps. Cam.

I had issues with a stud also. So I hauled them all, used lock tight and problem solved. But obviously if your leaking once the bike gets up to operating temp then your seal between your head and cylinder can't hold the cooland pressure.  Also check the gasket to make sure is not leaking from the cylinder bore into the coolant chamber then from the coolant chamber out.

You can buy single gasket.
