F1 Head Gasket Botch Up

[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.

Hope this might help others

Sounds like a good idea, I did something similar a long time ago, I fitted a 900cc kit to my 1971 CB705K1, this involves new liners pistons etc. But I started to get oil leaks from what I thought was the cylinder base gasket, so I stripped it down, put a new gasket in and replaced all the O rings while I was there, but it still leaked. So thinking that I might have had so small cracks (from the new liners) I cleaned off and "painted" the lower part of the barrels with Araldite, amazingly it never leaked again.
