Vibration and Noise contol

georgeknight · #1 01-23-2009, 03:07 PM

I came up with a simple vibration and noise contol for my bike engine. I had a piece of 1/8 inch rubber belt that was used on a conveyor. I cut it to fit in between the mounts of the front and rear on my bike. I also took my clutch cover off and made a template of the inside. Then cut a piece of the rubber belt to fit inside. I had to cut a circle in the center to clear the clutch assy. Used contact cement to glue it in. After I let it dry over night I gave it a good test drive of about 135 miles. I don't have the clutch noise or the vibrating handle bars. I also don't have the bolts loosing up on my bike anymore. Hope this helps someone with their project...............George

So hwo does this compare to the lead mounting as others have highly recommended? Some kind of strong impregnated rubber convayor belt material sounds interesting.

How about rubber tire, from an old blown out tire. Has anyone done that already?? Is that the same as a conveyor belt?

Any kind of harder rubber should be good.

I personally used leather belt strips.

I made a rubber gasket for my clutch cover a few weeks ago. I used 1/8" 'O' ring material. It really quieted the noise from that area. I don't have much vibration problem, but the clutch noise was no fun. Now it's nearly gone.

Some glue a mouse pad to the outside of the cover.

An old tire is basicly the same just thicker.

Hey Tom,
Did you mount the rubber gasket on the inside or outside of the clutch cover?

Does it matter?

Thanks.....

Well I have only had my bike a few weeks and I keep breaking the rear motor mount bolts. I also have put rubber on both mounts. My bolts keep loosening up or falling out. Can someone help me with this problem? George can you explain how you put rubber to quiet the clutch noise.

A lot of times, using rubber to mount the engine (or the wrong type of rubber) will agrevate the problem, hence your broken bolts.

Use blue (medium strength) loctite to keep the bolts in.

The 'O' ring material went between the clutch cover and the engine. I used gasket adhesive to keep the rubber in place until the cover was installed. Don't get too aggressive when tightening the cover bolts or you'll defeat the purpose. Use Loctite and just tighten the bolts until snug. This decreased the clutch noise a lot.
The sheet rubber, (mouse pad), glued to the outside of the cover apparently works too but I didn't like the appearance. 'O' ring material is available from Grainger. I used 1/8th inch; not much surface area for anything bigger.
