Engine Noise By montanaborn (Read 984 times)

It seems that I no sooner hit 10,000 miles on the Tank this week and the engine starts making noise. Oil is OK, no exhaust leaks, no power loss. The only thing I can think of is I finally need to adjust the valves. Could that be it?

It could be a roller; never thought about that. It just doesn't seem to be internal to the engine so I doubt (hope) it's anything major. Just noticed it yesterday so I didn't ride it to work today. I'll start by having my brother listen and see if it sounds like his did before he adjusted the valves.

Hey brother!
Have you checked for the loose nut behind the wheel? Have you been eating pickled eggs again?

I bet its your rollers, if you haven't replaced your rollers they probably are shot with bad flat spots and bounceing around in the slides. If its like rattling noise thats probably what it is. It could also be your belt if you haven't replaced that as well. They will stretch and start to slap around hitting the inside of the CVT, but that also has a different sound.

Valves will make a TICK TICK sound if they are adjusted just a Hair to loose(BUT A HAPPY VALVE IS A LITTLE LOOSE VALVE), now CLATTERING SOUND from the valves is not good that means they are to loose. But if you haven't adjusted your valves in all this time I would expect them to be TIGHT NOT LOOSE.

So I suspect its your Rollers.

Hey brother, bring your variator tool over next weekend. You can give me a hand. Maybe we can give that dirty scooter of yours a wash job while we're at it.

Removed CVT cover. Two year old belt looked great. Fired her up and definitely noticed noise from the clutch. Blew it out the best I could without taking apart and the noise definitely quieted down. At least now I know that I can ride it next week until I get new clutch parts bought and installed.
