I grew up in a small town and never really had the opportunity to attend any motorcycle rallys. Well, I had my first this weekend - a Poker Run in the Kansas City area. I guess there were between 200 and 300 bikes there overall for a 100 mile romp 'around town'. It was hot and I was the only one in gear :( (Joe Rocket Super Ego jacket, HJC Helmet, Firstgear Gloves and Oxtar Matrix boots - I'll get the pants next. The $600 for the initial set was all I could stand for starters)

Overall it was a fun trip. We had a police escort for the last 30 miles and that's the first time I've been able to 'run' a bunch of redlights in my life. Kudos to the police departments in the Kansas City, Independance, Liberty (and I'm probably forgetting a couple) area! I couldn't believe the level of organization and cooperation. There were no accidents or incidents to the best of my knowledge.

Anyway, I'll show you a pic of my faster blue FZ6 in the line-up and then I need to ask some advice on a possible problem I've noticed.

This bike is 2 months old, stored outside, covered every night for the last few weeks. It has rarely rained here during the period, however I did notice the sprinklers come on here every morning around 4am and they were spraying my bike on the back right side (which may or may not be important to this story).

Anyway, I hit my rear brake Saturday morning as I got to the starting location for the rally and was entertained by a loud squeal that basically was significant enough that it made it 'feel' as if the whole subframe vibrated. It is definitely repeatable and seems to only be present at low speed, moderate to heavy use of the rear brake. I've attached pictures to both sides of my rotor (the first is the inner side and the second is the outer) so any of you who are intimately familiar with something of this nature may be able to spot something odd. While I'm generally good about cleaning the bike, I have not cleaned the rotors during the 2 months I've had the bike.

Under normal stopping procedures, you might not even notice this as I primarily use the front brake with light rear brake pressure, but I was playing around and practicing quick stops with both brakes.

Thanks for any insight you can provide. It's driving me nuts knowing the problem (?) is there.

It looks like your back brake got reallly hot. Mine has 0 color change on it. Interesting to see what comes of it.

Looks like you got a whole lot of heat into that rear rotor. Do you ride with your foot over the brake pedal? Is it possible you have your foot on the pedal enough to make the brake drag when you ride? I don't know if you could even get that much heat into the rotor by just stopping. I'm sure some of the guys that are doing track days will pipe up and let you know if they've got that heat-discolorization from the track but I'd be surprised if they did.

I wouldn't think I have my foot 'accidently' pressing the pedal as I ride and I probably only cover it at all in-town. Once I'm out running about beyond the areas of frequent stoplights, I usually ride with the ball of my foot on the peg and my heel up - it's just more comfortable for me so there's no way I'm on the brake.

Would excessive heat on the rotor degrade it to the point it would be causing the noise? Am I likely just to find myself replacing it at this point? It just seems strange to me as this bike only has 1300 miles on it.

when on a stand, does the wheel rotate freely?

Yes, I put it on the centerstand all the time and rotate the wheel to clean the chain. However, I haven't cleaned it since I noticed this noise but that was only 200 miles ago.

Edit: I sure can go check right now!

Ok, the wheel rotates easily but I can hear the rotor touching the pads - a slight but consistent scraping sound as I turn the wheel. I don't remember hearing this before and I've cleaned / lubed the chain once since the 600 mile initial breakin service at the dealer (they did it at 600 and I did it at 1000 miles). I could be wrong but I think I would have noticed it if it sounded like it does now.

I went on my first poker run this past weekend as well. Unfortuantely, I can't say ours was uneventful. *sigh* Stupid harley egos.

It looks as thought your brake was dragging for a while and it got the rotor pretty damn hot. Check your pads to see there's adequate pad left.

Just spray a bunch of WD-40 on the brake and the noise will go away :lao

Really now,
Spray some brake/contact celaner in there and see what happens. The bike is only 2 months old, if it keeps happening just bring it back to the stealership and let them deal with the headache.
I don't think gettin the rear caliper wet would effect it but I could be wrong.

If I"m looking at this right, there's pad left but the inner pad doesn't look so hot. It looks like there are chips in it - possible debris damage?

I'd take it back to the stealer and have them take a look. That's not really normal, so don't buy the whole 'wear and tear' bull they'll try to feed you.

I went to Wally World and picked up a can of brake cleaner. Interestingly enough, I used the self check-out and they had to do an age verification. Apparently kids attempt to buy and sniff this stuff.

Anyway, I sprayed it on and cleaned the rotor up as well as I could and rotated the wheel a few times while it was on there before wiping it off. The noise is completely gone now even if I brake hard enough (just in the parking lot) to lock up the rear wheel. I'm still a little concerned about what you guys seem to see from my rotor.

Do most of you routinely clean your rotors with this stuff? Like I said initially, I had never cleaned the rotors since purchasing the bike (2 mos). I suppose I'll add it to my list of Saturday morning activities.

Thanks for all the replies!

good to hear the brake cleaner worked for ya, I love it when the cheap solutions do the trick.
IMO, the pads look fine. A little chipping around the outter edges is going to happen. I've seen it happen to my pads and didn't think anything of it, if the chips where b***** then that I might be concerned though.
If your that worried about it you can always take the caliper off and take a look at the pad surface to check it out. But my guess is it'll be fine.
As for the rotor I would rather see it in person before commenting but I wouldn't be that worried about it from the looks of the pic. What people are seeing is the slight discoloration of the rotor giving it that rainbow look. Overheating can cause, and if overheated to long your rotor could warp on you which would be a bad thing. But being only 2 months old I would have to say it's either the light causing the look or possibly that's the way it came.
Try to take another pic of the rotor in different lighting or from a different angle.

You shouldn't have to spray your brakes with the cleaner, its not a regular maintenance task.

Don't be satisfied just because the sound is gone. There is something wrong that caused the rotor to heat up enough to blue it, it is not normal. I'd head back to the dealer and have them look at it.

Hey Leere, glad to hear that you got rid of the squeak. A lot of times a squeak can be caused by brake dust on the rotors, which may be why the brake cleaner made it go away.

Actually, I want to hijack your thread a little bit and ask you what kind of luggage you've got on your FZ6. It looks like you've got hard luggage on there. Are they waterproof? They look really nice on the bike, so I was just curious. BTW, I've also got a pair of Oxtar Matrix boots, and think they're great. I've ridden in heavy rain with them (wearing a rain suit), and they kept my feet warm and dry. Nice boots.

The luggage is from Chase Harper and it's made from a material that really holds it's shape even when empty. They're not hard cases, and aren't waterproof. They're probably not large enough for a touring bag, but for commuting needs they fit the bill.

There's a few more pictures in this thread that I posted right after I got them:

You can find more info about the luggage here:

My only disappointment with them is how they seem to be fading due to sunlight. They just don't look quite so black anymore.

kinda off topic...I've yet to see another FZ6 in town. I was supposed to go to that poker run with the guys from church but get up. Wish I would have now just to meet you. Nice to see another FZ in the KC area, even though it's a slow blue one :cheers

Leere,

Thanks for the info. I've currently got some soft Joe Rocket saddlebags, and was just wondering about the cost to go with hard luggage. I guess those bags (Chase Harper) wouldn't be for me, even though I do have their expandable tank bag (nice bag). Oh well, guess I'll just keep looking.
