1990 RM 125 O ring head gasket help?

[jhkinzinger]

I'm rebuilding my top end and the head gasket is 2 o rings but there is no groove to place them on the cylinder jug or head. Do I just place one on the outside of the bolts and one on the inside? and crank it down? I don't have the manual.

seems 2 me like you got it right

I just bought the head/jug on ebay, they got the year wrong, it's an 89 cylinder instead of a 90.

thanks for helping

it should still work if you get a head gasket for a 89 cylinder
if not let me know i may have an 89 head laying around
i got plenty of parts for 89-90 rm 125 in my shed

Maby you could try to buy a Gasket sheet at local auto part store and cut it into the shape needed?.
