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.

Non issues with mine. Although I did just buy a new bracket because the rubber piece was starting to dry and crack

If it's a rivnut then just squeeze it up tight again with a rivnut tool. A bolt and a nut will do if you don't want to spend money on even a cheap Chinese made tool. If it still spins then drill it out and put a new one in.

It's a pretty common problem with inserts where the bolt is rarely removed. With a bit of corrosion it'll gall and start turning the insert with little effort. This page shows the tool and how the insert works. https://www.carbuildersolutions.com/de/rivnut-kit-budget

Yes I guess that’s it. Thanks for the info. Hopefully it doesn’t come loose, but if it does like the ones I’ve seen there are options for fixing it. When I was looking at it I couldn’t think
Of a way to replace the insert until I saw that tool
