• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Uptite Skid Plate Resonance

Anyone else have the problem of the Uptite Skid Plate vibrating at certain Engine RPM's on thier TE-630. Thinking of mounting with some sort of rubber bushing to perhaps dampen the vibrations. Sometimes I can put my boot on the corner of the skid plate to stop the humming.

I do have a real bad buzz at a very specific point in the rev range (fairly high revs). I hadn't isolated it yet, but my first thought was radiator guards. Will have to try the boot on the skid plate and see if that gets rid of it. Thanks for the post.
 
I had a similar resonance from my Uptite plate whenever I rode my bike clean. After going through a couple mudholes the resonance went away until the next time I washed the bike. I since bought a piece of skid plate foam and now all resonance is gone and less mud can accumulate between skid plate and engine also. Foam was a KTM part but a perfect fit for the TE630 and only $8. It fits snug between the frame tubes and will stay in place while you're putting the skid plate on also so no juggling required.

The skid plate on my new Beta has some rubber contact points, 4 to be exact. Doesn't seem hard to glue some on
 
My 610 was making sounds so I put a piece of one side sticky weather strip. No more noise. Once I removed it I just stuck it the places that showed whitness to being against the frame.:applause:
And yep, the Beta has pads that hit the frame when installed. :thumbsup:
 
I put two fabricated rubber washers (from a battery tray rubber mat) between the skid plate and frame on the two lower mounts under the engine and that seems to have resolved the problem on my bike.
 
I think anything soft that will hold up will work. I used a double thik strip of gorrilla tape on the frame tubes.
 
You can also spray the inside of the skidplate with Truck Bedliner. It will cut down on noise and vibrations.
 
Another trick is to cut some wedges out of dense rubber and wedge them between the side wings of the skid plate and the engine. This also prevents the skidplate from being bent inwards in a crash and damaging the engine cases. I found that one out the hard way. The wedges make the engine support the skid plate. I used truck suspension bumpers for the rubber. With weatherstripping between the frames tubes and the skidplate, and the wedges, I have no noise. Hope this helps. Cam.
 
I had resonance coming from the part that covers the oil filter area on my 510. Used a silicone plug from an old glass table, Have also used the kind of rubber plug you find just above the rad of a Jeep where the hood rest's on when latched. I got a bag full of them. Should be able to find some at any Napa. CarQuest, etc. Probably many cars had them, never looked into any other models personally.
 
Many fixes for the resonance but only one method will also keep mud from accumulating between the engine and plate. Before adding the skid plate foam I've removed over 5 lbs of mud after a sloppy ride. Now with the foam it's about 1 lb of mud that gets removed. What many wouldn't give to shave 5 lbs off their bike. Also that mud doesn't help with engine cooling any either.

Mine is just bolted on as-is, no padding or anything. I don't collect a crazy amount of mud or hear any weird noises.

I drop the skid plate and wash mine after any really muddy ride.
 
Any alloy skid will amplify engine noises. Sounds like yours may be vibrating too, in my case it was just multiplying the engine sounds by at least double. I have the TCI skid, similar design.

I used contact cement to glue a 1/8" sheet of epdm rubber to the inside under the motor. This knocked the sound down by about 90%. Couldn't be happier.
 
Thanks for all the input. Here is what I did. Bought some car heater hose at the car parts store. Cut about 1 foot length then slit it longways and put a piece on both lower frame rails, then mounted the the skid plate. Amaizingly quiet, even relfeclted noise off the skid plate is lower.

Will see how it hold up in the UP of Michigan next week

mine doesn't make any noise at all, but the side cover tabs fit so close that I'll bet there are those that are close enough to vibrate and make noise

mine's been quiet since the day I put it on....and after each oil change when it comes off and goes back on it stays quiet.
