I had a question does anyone know for a fact the dual ring piston kit for 88-04 model kx500s will fit my 86 Kx 500?

I'm putting my 98 KX500 top end back together and I'm wondering if I should use anything on the Head stud Threads?
Reason for asking is I torqued the head with fresh gaskets, Base and Head gaskets and everything seems fine until I fill the radiators and while I'm putting the Pipe on I see Air bubbles coming out of one of the head studs. There is no Pressure in the cooling system! I'm also using "Orange" Antifreeze is this the problem?
I'm baffled should I use something on the Head stud threads to seal it up?
Thanks

I use Yamabond to seal the studs.
what kind of head gasket are you using?

providing your cylinder and head mating surfaces are FLAT...OEM or Cometic head gaskets are the way to go.
did you lap the cylinder and head to be sure they were flat before assembly?

Great read.   I just picked up a used 03 that I'm in the process of rebuilding.   Pretty neat bike.   Always wanted one, now I have one.   It's a crate bike but i have almost everything for it minus the jug, head, piston and kips set up.  Can't wait to hear this thing run.   Ill be looking and asking for a lot of advise hope that's ok with everyone.  Thanks for the great read.
