Gasket or not?

Post by Mick Taylor » Thu Oct 18, 2018 7:06 pm

Hi all, I took my Classic out for a 30 mile spin to the pub and back last night and it is running like a watch, super smooth and responsive, it would be near perfect if the forks didn't chatter evil ......but that's an incurable issue as I understand it and not the subject of this post.

One of the alloy air transfer ports leaks a small amount of thin oily brown fluid....it always has done.

I can find no mention of a gasket in the parts book......nor on the AN exploded diagrams.

I'd like to fix this leak on an otherwise dry engine......I have a pair of O rings to hand, what is the sealing arrangement where the leak is?

There's never been a gasket there, so your sealant of choice.
ThreeBond, aka Yamabond, or RTV silicone works for me.
There's an O-ring where the elbows join to the frame; a smear of RTV there doesn't come amiss.

Mick,
As a Saab dealer once said to me about a noisy gearbox, "Yes Sir, they all do that"
Doug Hele came up with a fix using shims to reduce movement of the damper piston and reduce the rattle. AN may still have some, 48.0263 Shim .005", although there's a strong chance they'll need cleaning.

I hadn't heard of that before......you are right, AN do have some in stock so I'll order a few, thank you.... Very Happy .

That's a job for a dark winter day......scented by fork oil, what could possibly go wrong? wink
