Maintenance & Technical > KX500 Original
Broken middle exhaust mount bracket!
KX500freak:
it,s not aftermarket ,but homemade :wink:
i have taken a view of the dampers apart ,drilled a hole through the damper,
made steel plates of exact the same size .
bolted the damper right on the plates and back in place
still has the damping caracteristic but a little more firm mounting.
it works for me

I think I have done something similar with the factory steel/rubber mounts. The rubber tore loose of the metal so I drilled straight through all three pieces and put a bolt through the center of the whole thing to hold it all together. Honestly, I dont get enough time on my bike to test the durability of this fix so I wouldnt bet my life on it but if others have tried a similar fix and had good results then I feel better about it.

same story here indeed ..they tore loose ,a few off m anyway .
you have done it too ,smart thing,if you are not sure of enough dampingcapability,
you can use longer bolts and a contra-nut ,then you can adjust the tightening.
i have them in since 06 and no trouble at all :)

I had it happen on my YZ after it was stroked. The spacer plate raised the cylinder, which moved the pipe, etc, etc.
I removed all of the rubber between the two plates and replaced it w/ one of those shock mounts used for Harley oil tanks. They're available all over the place. Working great since 2003.

Gdubb, since you put a bolt through the entire mount it will then transfer all the vibration to the pipe, and may cause more vibration related stress cracks down the road. The thing I would do is take the rubber and bolt out and order an isolator from an industrial supplier. Here is an example.
