Ya you can only get away with torquing them on 2 or 3 times before the beveled edge the bolts go in gets deformed enough so even new bolts won't tighten the sensor ring to the crank.. I put a used sensor ring in mine with the old bolts and some high strength locktite.. It's still holding almost 30k later, and it gets spun up to 6000rpm on a regular basis..
