I'm running this nicecnc GPS mount on my KTM 390adv. The attachment location for the KTM shares the same pair of bolts as the windshield. I haven't been able to tighten it down enough to keep the bracket (and GPS unit) from vibrating/ bobbing around front-to-back. Anyone else running this part and have a solution? (I've tried adding in bits of foam tape, and pieces of plastic as shims)
