I have a 1987 500, bored 80 over, milled head,39 Keihin,bills pipe and silencer.Ordered and received a copper head gasket, says it good up to 89.5mm. After reading posts, having second thoughts about using it.

87 are known to have headgasket issues due to 1 less stud...Not positive but think getting the head O-ringed is your best bet from what others have said.I,m sure they will chime in.
Can,t fix stupid.:)

Ditch the upper motor mounts that attach the head to frame. That will help as well.

I was considering that, thanks for the advice. Any of you guys go to Gordon's Well ?

Don't waste anymore time or money trying to make a copper head gasket work.   The success rate odds are not very high for the copper gaskets and big studs.  The rubber type o-ring type head gasket is a no-brainer

That's about 15 minutes from my house. 17 minutes if Highway patrol is behind me.

No, the other way. I'm in Yuma, AZ.
