Molded-in threaded inserts: tips on removing the bolts

I've got an insert in my tank that spins when you try to loosen the bolt. Has anyone ever come up with a method of removing one in this case? It's one of the ones for the fuel pump. I had the classic "stalling on deceleration" problem this morning on my way to work, and I know from what I've read that most likely it is in need of the fuel pump mod. However, this is preventing it.

Freezing can work. It will mean putting the tank in the freezer for a couple of hours. Standard procedure on the TE630 airbox bolts that screw into nuts that are pressed into plastics.
If that fails spin the nut out by spinning it with an electric drill. This melts the plastic around the inserted nut. This is a drastic method, will work, but you then have to work out a solution to restore the nut to the tank.

I have also heard of getting the fastener hot enough where the plastic goes plastic (hah)... letting it cool and solidify- and then hitting with a blast of dust-off refrigerant, and trying to removing it then. I've never done it, and don't know if it would work here.

can you get the rest of 'em out? hell- if so, pull the plate and re-insert the insert (I'm cracking myself up here) maybe. I think I'm gonna hit mine with some anti-seize now after reading this, like I did already with the shroud screws.

does your TE have the 6-bolt aluminum plate or the 4-bolt plastic plate (2011-2014)? maybe put the bike's year in your info.

which fuel pump mod are you're referring to?

good luck.

Years ago I had 3 nutzerts that we're spinning on the tank. Just like ghte said, chuck the bolt head in a drill and spin them out. I don't remember what I used to rough the surface inside the hole up with, but I used some marine JB weld and let them sit a few days. When reinstalling the bolts, I used some clear silicone on the threads closest to the bolt head and put a very small amount of anti-seize on the lower threads and the very bottom of the bolt and tightened them barely past hand tight. The problem is galvanic corrosion between the two dissimilar metals that are used(brass and steel). The JB weld has held up now for over 5 years and no problems removing the bolts.

It is a 2008 TE250, and has the six bolt aluminum plate.
Thanks for all the great tips!
