so I've put the bike back together (for the most part) and I've got the front back on w/ the calipers. Well i give it a decent push and the wheel only makes about 1 revolution. Now before the crash at the GNF it would go around for like 10 seconds the calipers seem to be whats affecting it. If i loosen the bolts attaching the calipers top the forks, it spins much better any suggestions????
Guessing: do you have floating rotors? cause that sounds a little like rotors are not true and causing the brakes to pulse some.
you know that is very possible. when i fire put the wheel on i noticed that when i spin the wheel every revolution i would hear a a ring. anyway to fix this by hand???
Check the warpage on your rotor with a dial guage. Simply fix the gauge to the fork leg or other foundation and slowly rotate the wheel checking how much variation you have from high to low spot. More than 0.006 - 0.010" means you've a warped or bent rotor. I have experienced this on bikes with cheese rotor supports (SV1000S), and have been successful in using a maple or oak block (hard wood) and a hammer in conjuction with the dial gauge to return the rotor to near (within 0.004") of true. Do not apply the hammer to the rotor. Spend the time to figure out where the worst high or low spot is, and what adjustment will result in the least amount of beating on the rotor judiciously to return it to true. Good luck.
The axil on those bikes will let you put them in wrong. You have to line it up properly or it can be off a mm or two and still look fine.
sometimes you need to shim the caliper a little to make everything line up. One layer of duct tape between my left caliper and mounting blocks makes the differenc between one spin and 3-4.
