Clicking.. spark plug?

[Drewski77]

Hey folks. I have a '75 CL360 and I'm hearing clicking near the right spark plug. Any ideas? Thanks for the help.

Clicking near the spark plug...while the bike is running?

Most likely loose tappet clearance(s) on the right side. I would recommend going through the engine tune up procedure in the factory service manual. Adjust your cam chain tension, tappet clearances and then timing.

There will always be some 'clicking' in the valve train on these motorbikes. The tappets can be a bit noisy but a bit of clicking is normal. If its too quiet (too tight tappets) or too loud (too loose), then you can run into problems.

Does the plug cap / lead have any moisture in it? I had a GS1150 that would "click" off the #4 plug when it rained.
