I tore down the clutch and primary a few weeks ago on my 69 T'bolt. We went away for a week and then I got hit with covid. Ugh! I hope I remember where everything goes! Not really worried there. My biggest question is are there "while I am there" jobs? I will block the chain oiler. I prefer chain wax. I am replacing the rock hard seals. Anything else I should look at? Just want to have everything in hand when I am recovered.

Looking at my "71 A65 cam, it had a little timed crankcase vent with a spring. I wondered where it vented and discovered that it was to the atmosphere aimed at the chain and drive sprocket. If I were to plug that vent the crankcase would no longer be vented.

Yes. You need to check the alternator rotor hub. In your hand they can seem okay, in the vise can reveal a loose one.

The chain oiler on this bike looks like a feed hole at the back of the inner primary leading outside..nothing cam driven. Just a planned leak! Besides, the primary plug is vented.

Hi,
It would be well worth while to rebuild or replace the clutch centre hub (shock absorber)

A seven plate clutch conversion, makes for a lighter clutch.

Just to reiterate, we're talking about the chain oiler hole in the back of the primary chaincase and not the crankcase breather.

I've always had the chain oiler blocked on both of my A65s. One still had the little 90-degree pipe on it, which I simply pinched off. The other one had a nut and bolt in place of the pipe.

I agree that chain lube is far superior to motor oil (or ATF, which I run in the primary) in keeping the chain lubed (and less messy). FWIW, the best product I've tried to date is Chainwax (and I've tried them all, PJ1, Silkolene, etc.).
