Crankcase seal leaking
Spitfire:
Fingers crossed

Well, I got the bike back together and took it for a ride yesterday. I did about 250 km on it and the seal is holding and there's no oil leak. Hopefully it continues that way :)
MarkCR750:
Good news, great when you can get away with a dodge like that 👍
Moorey:
Report back regularly please. It's still early days yet. :)

Not all seals have 50 psi of oil pushing on the back of it. The lip is there for a reason.
And the seal in the picture is not a crank seal, I feel a bodge coming on and some damaged crank cases >:( looks like Fred Flintstone has already been in there.

Just read this topic, correct me if i am wrong, if the OP had 50psi going on in the crankcase this seal would be the least of his worries would it not, unless the seal is part of the lubrication system which i doubt because crank end float would reduce any oil pressure on the seal, i am not saying this is the correct way to replace the seal, just wondering where the 50psi came from.
