Ratchet strap to dirtbike footrest with visegrip on tire iron is pure innovation!

now pour seafoam over top it all and watch all the oil melt away.

I still have no idea what seafoam is. All I know is it gives you 20hp according to m.net.

I've tried PB blaster, fresh vice grips, and a welded nut. What's next? Should I try drilling it out? I've done that before, and with a precise machine you can drill out the center and go bigger and bigger with your bits until you can break up the threads and get it out, without damaging the existing threads. Although my drill press is far from precise. Other options?

If anyone suggests an easy out....neg props.

welded net and heat? if not you could source another rear, or send it off somewheres. it cant be too much for just one stud..
