Topic: CB750F1 head gasket repair

[Skoti]

Spent loads of cash doing up the bike over the winter and first time out discovered the head gasket leaking oil at the front outer head studs where they go through 'O' rings. 

Rather than spending more cash I tried a botch up and after 700 miles it's still holding .

Here's what I used:-

Cleaned away all traces of oil, grease and caked on grime with brake cleaner and cotton buds until absolutely spotless all the way around the front outer stud boss.


Applied this P U sealant/adhesive purchased from local motor factors and left to set for 24 hours.

I ran a bead of sealant from under the exhaust rose at the front to half way along the gasket edge at the side. I used a piece of small plastic tube fixed onto the nozzle of the tube to get access right into the gasket edge.
