Check the two alignment bolts under the carrier, they are probably not set equal. There are tiny indicator marks that you use to line the carrier up. Loosen the main bolts that fasten the carrier to the swingarm then adjust the two bolts so that your chain is tight enough and the carrier is aligned properly.
Anybody need some 20x10x9 rear Bandit XCs? 90% tread left with a couple of plugs but no leaks. $50 Got some aluminum nerfs too with red netting, one side is missing one of the straps but is still ok. $30
I have a set of aluminum nerfs with red nets that bolt to the foot pegs. Don't know what brand they are but they aren't the real bulky ones. They're in good shape but one side could use re-netting. $30
I've got some 20x11x9 Bandits I'll sell for $50. They have some plugs in them but don't leak any air whatsoever. Not sure how old they are (on bike when I bought it) but tread doesn't look under 90%.
