The first one i got off and it took a lot of torque to move it (guessing 80 ft-lbs) but it moved eventually. This one wasn't corroded or cross threaded - just seamed more like it was way over torqued to begin with.
I'll try heat with ice cube technology on the cap first. If that doesn't work then i'll max torque it with a 3ft extension bar and hope for the best. Do people have a habit of overtorquing these like to 125 ft-lbs for some reason? Now i can see why dealerships don't like to work on MC's older than 10ys -the lurking unknown?
