hello, just signed up and wanted to say hi...
i also have a question, so i have an 81 cm400 custom and it has a tisking sound in the motor, my first thought was the lifters, well i bought a feeler gauge and went through the lifters and i still hear the sound. i dont think its the piston knocking because its not burning oil or smoking, does anyone have any ideas..thanks |

It's just a noisy motor. Buy some ear plugs and don't worry about it.

Open the hood of your car and get your head as close to the engine as it is on your bike. Car engines aren't quiet either, just better insulated.

Air cooled engines are really noisy. The cooling fins act like 'speakers' and make any innocuous noise very noticeable. And, the source of the noise can be almost impossible to locate, because you frequently hear it from somewhere it isn't. Earplugs. Learn to love 'em.

It's when the valvetrain STOPS making a clattering-racket that you'd best pull the cover and whip-out the feeler-gauge. Of course, by then, it might be too-late....

![]() Honeslty though, the best you can get from a fourm is a guess. Regardless of the question, not being there to see and hear and feel it makes any answer a little suspect.

Run what the manufacturer recommends. Do not use automotive oil. Don't use synthetic in an old motor. You can get reasonably priced bike oil at Autozone.
