I just had a new tire installed on my front rim and after reinstalling the rim, I hear a scraping sound (although nothing appears to be scraping) from the front left caliper. I followed the correct procedure to re-install the rim, Torqued the left front pinch bolts to 22, torqued the axle bolt to 81 and then I sat on the bike and compressed the front forks several time. After that I torqued the right front pinch bolts to 22. The sound is very loud, seems to go away at about 40 MPH but then comes back. I put my bike back on my lift, loosened the axle bolts and pinch bolts and when I spin the wheel, other than the normal dragging of pads, it is quiet. If I tighten the left pinch bolts, quiet. Tighten the axle bolt, quiet. Pump the front forks and then tighten the right pinch bolts, the noise is there.
Amy suggestions guys? It would be appreciated, I'm not really sure what to do next.

After the axle bolt is tightened, and the right pinch bolts are tightened, do this. Loosen the left pinch bolts, sit on the bike apply the front brake and pump the forks. This will center the left caliper over the rotor. Then tighten the left pinch bolts. The outside surface of the left fork should be absolutely flush with the left end of the axle.
When the left pinch bolts are loose, the fork can slide left and right on the big part of the axle. Pumping the forks with the brakes applied allows the fork to move so that the caliper is centered over the rotor.
I have been saying for years that the instructions in the Honda Service Manual (and Shop Talk) are wrong.
Once the axle bolt is tightened, the right fork can not move at all. It is part of the axle lockup assembly. It is always the left side that is clicking.

I thought I had done that. I tightened the right pinch bolts (left ones were already loose), then tightened the axle bolt, pumped the forks several times with front brakes on, then tightened the left pinch bolts. What am I doing wrong?

You're left fork lower is too far too the right. what it looks like is the axle is not in far enough. it should be flush with the outer edge of the fork lower. start over and get the head of the axle flush before tightening the left pinch bolts.
Also 81ft lbs is for the rear axle not the front. The front is only 67 I believe.

Clicking is usually caused by the rivets on the rotor hitting the caliper when the wheel turns. Make sure that the fork is positioned properly. If you put a straight edge on the outside edge of the left fork, it should also touch the end of the axle. From the left front of the bike you can look up into the caliper to see if it is centered over the rotor. Adjustments are by moving the left fork toward or away from the wheel until it is centered. There is also a dimension in the service manuals.
If the caliper is centered over the rotor check to see if the noise is coming from the speedometer gear. The speedometer housing should not be freeq to rotate and should be against the hub on the front fork.

Pinch bolts are 16 ft/lbs Brake caliper bolts are 22 ft/lbs Front axle is 67 ft/lbs |

Thanks guys, I think I have it down pat, including the torque value for the axle. One more thing, once I've pumped the forks up and down, should I raise the wheel off the ground before tightening the left pinch bolts or tighten them with the bike on the kickstand?

Can someone snug them up for you while you are still on the bike?
Just curious, has the end of the axle been absolutely flush with the left side of the fork after the earlier tightening step? Or has it looked recessed?

Indybohm is correct on his answer to this. I have posted before that the axle should be almost flush with the fork. His suggestion of using a straight edge is a good one. This takes all the guess work out if it

No, my axel bolt is not all the way in, it's sticking about about 1/8" so that is more than likely the issue. Unfortunately I don't have time to work on it right now but I'll let you guys know after I've corrected it.

All is good now thanks to you guys. I still have a question for you though, should the axle be that hard to install? I used a rubber mallet but it wasn't easy. I have a 2008 Goldwing and you can almost pull out the front axle and push it back in by hand. Why is the Valkyrie so tight?

I'm guessing you loosened the pinch bolts  ... Maybe it is just that your axle hasn't been in or out in a long time? Did you clean it and put a little grease on it? It doesn't spin or anything, but a light coat of grease helps it slide in and out when you're doing maintenance... -Mike |

This is an amazing forum. I am having the exact same problem on the left. Have followed the manual three times!.
I'm sure if I check the axle and then pump the forks all will be right in the world.
Thanks for sharing.

Amazing I have been scratching my head on this one for 3 days. Followed the above and tire spins free with only the usual and normal brake pad rubbing.
THANKS!!
