Bought an RS 200 a month ago, runs fine everything seems well on it, but after it’s been running a while especially in traffic there is lots of vibration in the cockpit, first of all I think I need a new thermostat. But there is a very loud drone inside. Last owner as put it on power flex engine mounts as it was going to be a track beast. But I want it as my daily and was wondering how to make it a bit quieter inside and no vibrations that hurt my ears !!!
