flatlands raceing skid plate noise

Has anyone figured out a way to fix the noise from the plate? Mine is real loud at highway speeds and when backing off gas deaccelerating .

Yes - insulate the plate with something. I think some have coated it with a brush-on plastic-coat style stuff.

Some just use a foam insulation material with a sticky backer and stick it on plate.

It's been mentioned numerous times around here. Just not sure where at the moment.

Bingo. <-- clicky

I sold my aluminum plate, but I used a chunk of rubber flooring material and it quited the noise. I just cut it in the shape of the plate. Avoid things that are too thick, it makes the bolts a pain to get in.

thanks all. I have glued a piece of rubber material on the plate. Waiting for it to dry and will put it back on today. I will post the results.

Works great! It still makes a little noise but if you had not heard it before you would not notice. You can hear the motor now!!

What exactly was the rubber material you used.
The skid plate noise drives me crazy!

I just took mine off. Drilled a bunch of holes, sprayed auto undercoating on the inner
side, and put 3m double sided mounting tape on the frame rails where the plate might
touch. Rode today and it's 75% quieter.

I used the stuff truck companys use to keep stuff from sliding. It is about 1/16" thick. Glued it to plate. I would think any rubberlike materal would work. I would say the noise is 95% gone. You can hardley tell it.

I went to Harbor freight and bought the rubber step matte which has an adhesive on the back. I works fine.

I had trouble finding a suitable sheet of rubber to line my skid plate until I came across a roll of tool box liner at Princess Auto (kind of like Canada's version of Harbour Freight).
I only lined the bottom and not the wings. I used silicone to glue it to the plate.
I am happy with the results. I would say it reduced the noise by 75%. I wonder if lining the wings would improve that but I don't think I will. The noise at it's present level doesn't bother me anymore.

I used some reticulated foam that I had leftover from making sailboat cushions. Strips rubber cemented to the skidplate, between the frame rails and it knocked out 85% of the noise. The howling is pretty much gone.

That's what I'm doing now before install, I probably read this a month ago and got the idea.... No extra holes although that's always an option.
Using some "Premium" rubberized undercoating from the Dome Hepot and plan to apply 4-6 coats maybe depending on how it looks after the first two dry. I considered the harder non-skid/flight deck stuff but figured it would be a little too hard to absorb noise.

thanks for the tip!

Use garden hose gaskets as spacers on the back side of the skid plate. It removes all contact between the plate and bike. No more vibration. The sell them in multipacks at home improvement stores.

I installed my skid plate from Flatland, and I have no issues when it comes to noise. I've seen people glue bike tubes to the parts that touch the frame and add rubber washers in order to get rid of the noise.

I wrapped my frame rails in inner tube from an old mtn biking tube and zap strapped it on. Has never been a problem.

Just bought a skid. Trying a coat of line-x on the inside. Going out this weekend. Hopefully the noise wont be a problem.

I sprayed mine inside and out with black gravel guard, like they use
on the rockers of cars, no noise from mine, I used blue locktight on the
bolts so they wont vibrate loose, cheer`s

I got a can of Plasti Dip Spray from hardware and sprayed on 5 coats on side facing up over several days and then got some electrical grommets for the bolts. Seems at least 75% quieter.

stuck some rubber sheeting on my yesterday and if anything the noise is worse!

I used dynamat on mine (car audio sound proofing) WORKS AMAZING!

I just used some half inch foam weather stripping. i stuck it on the bottom of the frame rails and on the rear most part of the skid plate. No more noise.

I used the combination of adhesive weather strip on the frame rails, and plasti dip on the plate, and you can't even tell its there anymore.

I had Rhino Liner sprayed on mine plus put a layer of rubber floor mat cut to shape and put rubber washers between the plate and mounts........I took the thing off and put it in the closet.......gonna get a piece of 1/4 inch think rubber...cut to size... mount it with the front two bolts and fold it back under the motor and secure it with the two underside bolts....not as protective as the metal plate but my sanity will be restored

Dont bother with a rubber mat as a skid plate, it will bend or rip when you actually need it, that stuffs just too soft.

Go get a big plastic cutting board and mount it the way you described but you will need to heat it to bend it. These are as tough as the alum ones, I have one on my other bike, it was a pita to bend but works great.
