So when I hit a large bump or series of them, I hear and feel a clunk in my front end somewhere. don't believe it's in the wheel assy--checked and rechecked it. I know the fork tubes are tight in the triple clamps. Would it be the steering head bearings? If that's the likely thing, how to check those--jack the bike up and start pulling? Thanks.

take the spring clip out of the front brake calipers and put some more curve into it and re-install. your pads are bouncing in your calipers because those spring clips aren't keeping enough tension on them.. don't go ballistic on bending them though. doesn't take a whole lot. you'll be able to feel if you have enough tension or not when you go to put them back in.

Next time when you go over bumps lightly apply the front brakes and see if the noise goes away.

http://www.rattlebars.com/valkfaq/index.html#NOISEIT GOES CLUNK WHEN I STOP! It sure does! The Valkyrie is equipped with "floating" calipers. The calipers are attached to the caliper brackets (these, not the calipers, are bolted to the forks) by a set of rubber booted pins set in holes. The holes are larger than the pins so there is some free play there. When you back your bike up to turn it around and apply the brake in reverse, the calipers will move to the rearmost position. When you apply the brake at the next forward stop the calipers move to the forward most position and the pins strike the other sides of the holes.. CLUNK! You can see the calipers move if you apply the brake and rock the bike forward and back. When you stop at a red light, the calipers will move to the forward most position then when the bike "rocks back" after being stopped... CLUNK! http://www.rattlebars.com/valkfaq/index.html#NOISE

Still, based on everybody's input here it might just be the calipers bouncing around or something. I wonder if they have a bit too much "float" in them.  Thanks for the feedback. |

take the spring clip out of the front brake calipers and put some more curve into it and re-install.
Just did the (rear) brakes a few days ago, and the curve in the clip does tend to flatten out a bit, specifically develop a larger radius. I had a new spring clip to compare side by side. |

Mine clunked when going over bumps, until I lightly applied the front brake. Front pad springs need some work and make sure the pin that the pads slide on are clean and lightly greased. |

Okay, will do. I'm just relieved that it's not my steering head bearings or something much more serious. |
