Triple clamps

Does anyone make an aftermarket upper clamp that fits the KDX fork tubes?

And does anyone else have the problem with their handlebars twisting in their bar mounts? I've wrenched them down pretty tight, but I assume the rubber grommets in the mounts are supposed to absorb vibration and allow the steering set up to give a little under a hard impact?

I dumped the bike pretty hard today on its side and as soon as I picked it back up, I instantly knew something was tweaked, I have a new set of pro-taper fat bars on there and I figured there was no way they bent that easy. Im using a different bar mount made by MX Bonz and thought one of the bolts may have bent but the things look straight as can be...any suggestions appreciated. I figure the stock cast aluminum upper clamp would crack before it would bend.

Thanks for the suggestions. I realize now on impact the rubber compresses but sometimes does not release giving the appearance that the bars are bent. I loosened the bar mount on the one side and then retightened and it was good to go.
