Looking for insight from owners with 2005+ yz250s. I just bought a leftover 2017 and have seen a few yz’s in the past that have had problems with the lower exhaust mount. There is a small tab on the frame where the rubber mount is bolted and inside the tab there is a threaded insert inside the aluminum tab in the frame. I’ve seen a few cases where this insert starts spinning in the frame and does not let the mounting bolt tighten down. Anyone here ever have that problem and did you fix it? I took that bolt out and put some Anti-seize on it hoping to prevent that insert from breaking loose.
