1973 cb350 cam timing and valve adjustment question (with pictures)

Is my cam timed correctly? Reassembling, first sl350 I have put together. Here's a few pictures

This is my engine at LT, L at top on cam sprocket, nub is up on points end, tension is on the cam.

Here's the L

As for valve clearance adjustment, where does the cam need to be? They are all down at 90 after LT. I believe the flywheel says J. Is this the place for clearance adjustment?

Here is the second LT. It doesn't want to sit right on it without me holding it.

Nub-up at LT is correct. Your timing is right.

As for valve adjustment, I rotate the engine until you feel it "fall" in the direction of rotation. That's the cam-weight working its way to the low spot, which is about 90º after top-dead-center on the compression stroke of the left cylinder. You will notice that you can spin the crank freely at this point, assuming your spark plugs aren't inserted.

90º ATDC on the left is also where you adjust your cam-chain tension. Be sure to put a slight tension on the crank anti-clockwise as you adjust the tension, so that all of the slack is in the rear of the chain.

place the pin on the camshaft at the 4 o'clock postion,,adjust and set your cam tensioner..........good luck
