Hey all,
I've had a bit of a grinding sensation in the front wheel since I put a new tire on (Continental something or another, cheap & feels good). I can't figure it out. I've ridden about 200 miles since the new tire; the grinding isn't getting worse or going away.
Possible causes:
-tire is not balanced. I'd think this wouldn't feel like a grinding though
-front brake pads re-bedded weird. I forgot to do the usual bedding in when I replaced the wheel. Grinding seems to go away on braking.
-there was a bit of scoring on the axle, on the left side where the bearing is. Hmmm. Bearing seemed to spin fine though.
-axle nut not torque'd to spec.
Thoughts? Thanks!
I'd look at the brakes since the noise changes when you apply them.
If it is not the brakes, next suspect would be wheel bearings. It wouldn't hurt to loosen the pinch bolts, retourque the axle and tighten the pinch bolts.
Thanks - hopefully they're the culprit, and the easiest thing. They (EBC hh's) have over 10k miles on them :-X

Ah man I hope it's not the bearing! But I'll try that too. Always paranoid about axle torque.
Also, try loosening the axle pinch bolts (at the bottom of the fork) and bouncing the front end a few times. Then tighten the pinch bolts back up.
Wheel on backwards? :-\ (pads hit a different "bed"?)

Take a look at the rotor where it passes through the caliper and see if they are touching.
Who installed the wheel?
Also, SOME pad drag noise is normal.

Wheel can't go on backwards because of the speedo drive.
No?

No, yes, no, yes, no, yes ......
I really don't know, just thinking out loud...
Maybe it's a wrong-sided speedo drive that's making the noise [cheeky]
Excuse me, I'm not in a useful mode today ;)

Me too...
idea bouncing is good. [thumbsup]
What's the size of the tire you put on? Most of not all monsters take a 120/60 on the front, if you put on a 120/70 the tire might be grinding against the fender.
Did you use windex to put the tire on? If so did you leave the rotors on during the swap? I did that last time and since then I get a little rubbing noise when coming to a complete stop or pulling away from a stop after the brakes are warmed up. I wiped them off after the change but I think you have to use brake cleaner to get the residue off. I would describe the noise as more of a rub then a grind but either term could apply.

Impossible - only one caliper & rotor ;D And speedo works fine.
I also checked to make sure the tire's going in the right direction. It is.

Me & a buddy, with beer of course. Clearance from rotor to caliper is disturbingly close, but my 1098 brakes are the same way. Rotor not warped. Definitely not a brake dragginf feel, unless one of my pads is done.

160. Clearance between tire & fender isn't great; I may throw the SBK fender back on. It does seem a bit like fender rubbing.

Nope, spray bottle w water in it. The grinding isn't druing stopping or taking off. It's just rolling along, at varying speeds. Not constant.
A-ight, appears to be fixed - I swapped out the fender, loosened & re-toqued all the bolts. I don't think it was the fender; no rub marks on the inside. So it was probably the torque on the axle and/or pinch bolts.
Thanks all for the support!
