I have a 2011 GSX 550F and have gone over the whole sled last year with a fine tooth comb replacing anything that needed to be replaced. I put a set of yellow sliders on it and after a couple of rides there is yellow shreds all over the skid. Seems to be wearing really bad at the front idlers where the track starts to curve up to the drive axle. I've loosened the track and made no difference. Only have maybe 100km's on it. Any ideas would be great.
