rear sproket

[joeyds450x]

if anybody is having problems with there rear sproket coming loose check it over really good, mine came loose a few times and i think i found the problem, it was snapped in two places, im not sure if this was the problem 4 it coming loose all the time but its the only thing i can think of.

it happened to me too, twice i got it taken in, k but now my back brake doesn't work

The bolts that hold on the rear sprocket come loose. Be sure to check them after every race/ride. It has nothing to do with the sprocket being broke, I replaced mine and it still does it, new bolts and everything. And the back brakes do stop working. Re-bleed them and they will work again. If you can use one of those bleeding tools. It will make the process go by faster. And then poke a hole in the rubber part under the resevoir cap.
