I know his is a well covered topic, but a lot of the posts are from a good few years ago.
I have a small but annoying leak from the top crankcase joint immediately behind the barrel on my 1972 Commando. It only leaks when running. I don’t have any other leaks and since she is running well I don’t want to do any major tear down work at this point.
Compression is OK so I don’t think that is the cause of the crankcase pressure.
I like the look of the CNW breather mod and it makes sense to me to have the valve attached to the crankcase so it gets hot and condensation issues are avoided.
But.. it ain’t cheap - especially when you factor in 66USD to get it to the UK!
Please can I have feedback from anyone who has fitted this mod. Has it fixed these types of weeps/leaks?
Also are there any other alternatives that attach directly to the crankcase that I should consider?
