Gear wobble/oscillation

Fishermanblues said:

Hi everybody, I'm new around here but I have been lurking for months while I was waiting for my bike to be ready. I noticed a whine/squeaking noise while I was riding with the clutch engaged, so i tried adjusting the clutch by changing the cable/arm adjustment, this didn't fix the problem. So next I took off the clutch cover to see if adjusting the clutch with the flower nut would fix the problem. However with the clutch cover off I noticed that the large gear is higher at one edge than the other, causing it to wobble when the bike is pushed with the clutch disengaged. I then took the bike on a ride without the clutch cover on to see if it would wobble when the clutch was engaged, and it did. I then proceeded to remove the clutch plate to see if that would fix the problem, but it still wobbles even with no clutch plate.

Is gear wobble like this normal? Would it cause the whine that I hear when I ride with the clutch engaged? Will it make my clutch wear out faster?

Any help or suggestions of what to try next would be greatly appreciated.

Thanks, Andrew

whine/squeaking your hearing Is the cheap China Gears.

You can try different Things ..Gluing Mouse Pads Over the cover .
But
One of the best easy fix i do is .It wont fix in Completely BUT you will hear a noticeable improvement.

Here at Blue-Collar ..We call it a clutch Muffler

Take the 5 screws off the clutch cover Lay on a cardboard box.
Trace the outside of the Clutch cover and cut the inside of your trace.
Place inside And tighten all hardware. It will not do any damage or soak up grease from gears.
I have been doing this for over 6 years with pretty good results.
What your doing is taking up space the gears have to amplify the gear sound.
Sort of like A drummer Putting a pillow in a drum head.

Hope this helps.

Cheers

I tried that inside noise damper. My clutch rubbed.
It damaged my clutch pads.
It is much safer to glue carpeting, or ghost0,s material to the ourside of the cover.

Also glue some one inch long pieces of fan belt or old sparkplug wire between the cooling fins. It does wonders for noise reduction.

I was not being clear .
I did not use cardboard.
I used a plastic material coroplast
There was not enough room in the housing for the clutch and the coro.
Your photo shows the clutch is contacting the cardboard material.

Thanks for all the tips, I will give the cardboard a try. However I'm still worried that the wobbling gear might cause issues, I don't think that it engages evenly with the clutch. I'm having some problems adjusting my clutch; it slips when I try to engage it when starting, but it also rubs when I lock the clutch with the little pin on the handle bar. I have tried cleaning the clutch plate and the "pucks" with brake cleaner and I have tried adjusting the clutch many times, but to make the rubbing go away makes it slip all the time and to make the slipping go away makes it rub all the time. I have reached as close to a compromise between the two as I can, but it still doesn't seem right.
