gently caress, I missed the warhams discussion by a page. Anyway, for the third time I had someone ask me if I was skydiving while I was running errands in my riding suit. As in there's no irony, they thought I was jumping out of a plane then decided to grab some milk on the way home.

I've had the same thing happen to me several times. I think it says something about riding culture in the US when people are more willing to accept that you jumped out of a plane than wore proper equipment to ride a motorcycle.

Finally found out why two consecutive sets of brake rotors were warped... My front wheel must have hit a curb or been in an accident before I bought the bike, and it's very slightly warped -_-

Are they actually warped or are the buttons just dirty? I need to clean the buttons on my rotors every ~6-9k of commuting or the rotors start to pulse. A bent rim shouldn't affect your rotors at all, unless your bearings/spacers are hosed or the mating surfaces where the rotors mount is messed up, as the rotors (should be) fixed in space against the brake calipers. If the wheel doesn't have side to side play, the rotors are roughly centered in the calipers, then it's probably a problem elsewhere.

Get some brake cleaner, a bolt about the size of the ID of the buttons and two nuts that fit the bolt. Thread one nut onto the bolt, stick the bolt through the button and thread the other nut on so the button is sandwiched between the nuts. Tighten the nuts until turning the bolt also turns the button. Grab a ratchet and your brake cleaner and spray the button while you rotate it until you can feel it turning easier. Repeat for the rest of the buttons. When you're done spray the rotor to get any gunk off it That's how you clean your buttons. The first bike I had to do this on was my versys. At just 4K miles the buttons were dirty enough that the rotors no longer floated and the brakes shuddered like crazy. After the cleaning it was like a new braking system.

Unless they're totally seized, you don't need to do any of that stuff with nuts and bolts, just wear washing-up gloves and use your finger to work the buttons loose. Takes about ten minutes to do all three disks.

Well, I can't figure out what else it might be, since four entire rotors so far have had the same pulsing problem. It's not the bearings or anything like that - it's speed dependant, when slowly rolling to a stop at a light, you can feel half the diameter of the rotor grab and then let go. Braking hard at high speeds chatters the whole front end (can get video on my next TD). How would rotor buttons affect that? Idk if it matters, but I have the speedo magnets on one side for the sv gsxr speedo fix.

Going to have to try that, my brakes are shuddering quite hard when braking from speed and I'd assumed it could only be a warped rotor.

Speaking of brakes, I sometimes get a loud click from somewhere in my bike's front end, right as the bike settles after hard braking. So I'll accelerate up to a good speed, brake hard, and after the weight shifts forward I hear a single loud CLACK. It doesn't happen every time I decelerate, only after I've gotten up to a good speed; it doesn't even happen every time I decelerate from high speed; and it never happens more than once in a given cycle. I ask about brakes because I don't think it's the steering -- I don't notice any slop or notchiness in the stem, or other signs that something is wrong. But the sound could be coming from anywhere. What should I be looking at? Sagebrush fucked around with this message at 21:17 on Apr 9, 2016 |

I've had nothing but bad experiences with those, they always seem to get shudder.

Braking hard at high speeds chatters the whole front end (can get video on my next TD). Modern rotors are designed to "float" and self center between the carriers and the calipers for maximum efficiency and consistency in braking force. They can move side to side a little bit so they sit right between the pads. If the buttons get gummed up and jammed, they don't "float" anymore, and instead they're locked at whatever location they jammed up at. So under braking the rotors center on free buttons, but then it hits one that is packed with grit and can't center anymore, and your brakes pulse as the rotor suddenly moves a bit to one side. If you can't freely rotate the buttons by hand, the buttons have have seized up. You might have caused inconsistent buildup of brake pad material on the rotors by riding them like this for an extended period, but usually you have to go pretty hard to have that happen. Modern rotors fully floating rotors don't "warp" under any normal (or even track/race) use. At best, you just need to clean the buttons, at worst, you need to scrub the inconsistent brake pad material deposits off with a rotor honer or some sandpaper. You pretty much have to bend the things by hitting them with something to get them to warp.

Head bearings are easy to check if you jack up the front of the bike. I can confirm some forks make noise too, if I sit on my bike and roll it forward while sharply jabbing the brake I can make it go clunk-clunk-clunk from the forks.

Some brake calipers also allow a bit of pad movement that you can hear as the pads slide back and forth

Yeah, those signs were originally only made to try and appeal to people's "aww a baby" feelings and make them drive more carefully. Just a dumb fad like the suction cup Garfields. Later, someone made up an origin story about a baby rolling under the seats in an accident and being left behind to die by the EMTs, and that took hold because people love inventing and repeating horrible stories about dead babies.

Anyone else ever notice that cars with those stupid baby on board signs in the window are also some of the most aggressive, not-paying-attention, cut-you-off-and-don't-give-a-gently caress cars on the road? If anything those signs should be required to only be mounted on the inside of the front windshield or on the dash, facing the dipshit driver to remind them that they need to drive more carefully because of their own child onboard?
