Sometimes when I'm trying to get a stoppie going, the forks vibrate/chatter sort of. New pads, lines and fluid...so those shouldn't be an option. it just started saturday. Should I bleed the brakes and see if that works? Thanks for the help too gents.

 

Have you changed your rebound?

 

not enought to have this problem...it's coming from the brakes. I know that much

 

maybe the disk are messed up because there only to float so far.

 

speaking of rebound... i never really messed with my fork setting. I roll about 200 ft but i think i could go further if my forks didnt bounch so much. anyone got any on the top and bottom adjustments on a gsxr 6?

 

same thing happened to me two different times and two different ways..........

1) Glazed brakepads WILL cause a chatter from the brakes, especiallly as you start to sow down in an endo from rolling it out from speed.

2) Loose steering head bearings WILL cause chatter, especially when going to pull an endo up.

I take VERY good care of my bike when it comes to maintenance and I still forget from time to time to tighten the steering head bearings, and its fairly simple to do, pull the top triple and you should be able tell if anything is loose and tighten it up pretty easy.

Also, I've smoked a set of HH pads up front in a WEEKEND of rolling endoes, so if you went that route, trash em and get you some stockers.

 

stockers on there, but I'll check the head bearings next time I ride, and I'll clean the rotors and see if that helps....hopefully won't need new pads.

 

if ur rockin stockers ur ok......more than likely gonna be the head bearings.....easiest way to check without pulling anything apart is to hold the front brakes and shove down and pull back on the clip-ons and see if you feel they're loose. I usually take my left hand off when I do it and put it where the top triple meet the frame neck and you can tell really easy..........good luck man

 

check your rotors, they may be loose.

 

so just like a bike (mtn bike). I'll check tonight. I'll also check if the rotors are loose. was a little intoxicated when i posted last night. might get new front pads just to be safe.

 

so it's not the head bearings. when I roll the bike backward slow and hit the front brake and let off...it makes a tap/clank sound from the left pad area. new brake pads?

 

pads, rotor, caliper.....check everything......if you have a race oriented cycle shop (not a dealer), typically they can check for any warpage of your rotors and tell you whether or not you need to replace them.

When my pads were glazed, they looked like someone had taken a butter knife and spread the surface of the pad smooth.

Hope that helps.

 

take the pads off and scuff them up on the concrete.

 

nah man, me and Shawn do all the work on our bikes.....noone touches them.

I'll have to check next week one night. the sound comes from the left front caliper area, right there. you can see the pads move when you let off the brake when it's rolling backwards. I'm not gonna stop wheelieing but the quest for my garbage stoppies is off til I get this fixed.

 

is there a birdnest in the left caliper?

 

I hear ya....I do 99.99% of the work on my bike, I just don't have the equipment to be able to guage how bent or warped things are. If you do have that stuff, you should move into my town so I can use em

 

I have a ton of micrometers here at work (the other building). I'll pull them off and check to see if they're good to go. and the trueness....I use a flat worktable.

 

Survery SAYS:

no, only under the seat...thanks for reminding me....time to check for eggs

 

update. continentals **** for use. I couldn't get up a spreader in 2nd even after a decent burnout. I'll be taking this tire off and putting on a normal stunt (takeoff) soon...like monday.
