Stripped the threads on the brake caliper. I had some problems with this bolt before....but got it to torque up right. I'm going to try to use some thin copper wire to get me by till I can replace. New brake caliper is $351.00...........sheesh.
Ride Safe !!!

You can get a used caliper off ebay, and rebuild it for substantially less. They also make heal-a-coils for threads like that, at almost any auto parts store

I use a torque wrench for the axle bolts and steering neck. Will use it on the cylinder heads if I happen to be doing that kind of work, and internally on the rods and crank. That's about it, can't remember last time I stripped a bolt or threads and have never had anything fall off in over 60 yrs. of riding two wheeled motorized contraptions of some sort.

That is because your so experienced with all the parts of a Valkyrie....but I'm going to do the same. How about a helicoil?

That should work fine as long as it's the correct size. I agree with another post re. Ebay, don't buy a new one, way overpriced. As for experience on the Valkyrie, they didn't make them back in the day. I just learned how to feel the tightness of various sized nuts/bolts. Good luck on the repairs.

If it was the brake caliper stop bolt that is stripped, it threads into the swingarm, not the brake caliper mounting plate. This would be item#11 on the Swingarm fiche.

Contact me with the exact part. I probably have it in stock.

Under normal riding conditions, and with the axle bolt properly tightened the bolt you refer to is under no force at all. Only under emergency hard braking is the bolt displaying it's usefulness. Only under hard and emergency braking. I think a helicoil will be adequate since there is a pilot for the bolt that handles the forces and the threaded part is only there to maintain a position of tightness.
Care should be taken when drilling and threading for the coil not to disturb the pilot hole for this is the most important part (feature) of this particular safety system.

The helicoil worked like a charm.....however there was some "extra" threads that came out of the rear of the (caliper) bolt hole that the dremel took care of. I did have to borrow a 31/64 drill bit to dill it all out. We went slow and it was perfect after being tapped slowly too. Many thanks to all that have commented. I would be too poor to ride if not for the wealth of knowledge on here. Again....many many thanks !!
I just went for a test ride after getting everything tightened up. This Yokahama ENVigor feels more like a MC tire than I have ever felt in a car tire. Rear end has good motion to it. Can't wait to try it out in the sunshine!!
Ride Safe !!!

The guy at TireBarn said the ENVigor was going to discontinued? Not seen anything in a search on it yet.

I guess this was not the Brake Stop Bolt?

The Only thing I use a torque wrench on is the rear axle nut on my Valks. I know when tight is tight. Guess I'm not sure why I use it for that.  Not like the axle will move front to back like in the old days.
