1996 RM 125 Blown Head Gasket
I could use a bit of help.
I am fixing a 1996 RM 125 for a young fellow. It is his first bike.
He got it in a non running condition.
I am a long time rider starting with my first bike a Hodaka Ace 100 but my newest two stroke is a 1972 Yankee Z.
I have worked on many air cooled Two strokes but never a watercooled one.
His bike had no compression so I pulled the head.
I can see were the steam has cleaned off the carbon on the piston so I know the head lost its seal.
Thesewatercooled bikes only have two O Ring sealing the head? I did not see a copper head gasket.
How is the best way to insure that the sealing surfaces are going to reseal once I install the new O Rings?
The Cylinder is stilll showing cross hatching on the cylinder wall. Can a Nikasil cylinder be honed like a steel cylinder?
Is there a PDF online of the service manual?
