Who has made Sound Dampenesr ?

[PAPAROACH]

Are the Engine sound dampeners worth a ****? They look very cheap on SickBikeParts.com . Does anyone know what they are made of or made them ?

I got them. They are mylar-faced plastic elastomer. It's a strechy plastic sound deadner that stops the flat surfaces from resonating cutting the noise they make.

It's just a cruddy photo of a good product

Some people use cardboard glued to the inside of the clutch cover.
I used carpet remnants glued to the outside of the clutch cover.

sound of gears

I used a cardboard cut out and a spray-can of contact cement(cost about four bucks) and it worked really good on my old ride. I think I will try it on my new motor when I get to the point when that is all I am worrying about.(I still have a full can of sticky left)

I have heard of mouse pads being used also, But I think that is too spendy for my taste.

Here's our blurb:

JNMDamp-Pro - for quieting your engine - from inside the covers. The Aerospace dampening material is layered and constrained viscoelastic (flexible and it flows) damper that converts the vibration energy into low level heat. Shown in the picture is the reflective foil side (foil is a hefty 6 mils). Material overall is 70 mils thick and very dense.

The deadening material is very dense. Nothing like cardboard or mouse pad. To my feel and ears they work. The material is very gooey and sticky - but flows just enough when sticking in place.

Yeah sometimes my photos suck. Haven't had time to snap a better one. We sell a lot of the dampeners and people are happy with them. We took this line on in January and quickly became their #1 retailer. I think that deserves a better photo Anyway, good, bad, or indifferent - let's see some feedback on them.

Bad photo (max it out) on an oak table (you can at least see the shapes):

hehehe, they actually look better in that photo.

Even though I haven't run the motor yet I am pretty sure they will do the job. You can tell that when you tap it and instead of a metallic sound it just sounds dead.

I discovered that 1 of the 3 pins in the clutch sticks up higher than the others so I cut the center out a little bigger because the pin was dragging on the material and I didn't want it to ball up and jam the gear

Thanks for the awesome replies. I will buy them from the Sick Bike Dude now that i have a idea on there effectiveness.

yeah. ive got a set on the way myself.

i mean it wouldnt take too much to deaden my engine sounds, because i think i got lucky on the "motor lottery" and got a good one.
everything seems balanced and and solid in it. very little engine tapping..
i was honestly surprised; other than the bike it's self being a rough ride with no suspension, the engine hardly vibrates like i'd expect it to.

None-the-less. im all for quietening down the noise as much as possible.
and im sure these will work for me. but i'll let you know if they dont... otherwise i will probably forget i even posted this
