it seems like my 91 dr 350 while riding it looks like it is turning slightly to the left....the bars are new, so i know that aint the problem, i recently bought the bike, maybe it was laid down or hit a tree, i dont know, but with the bars straight, it wanders a little to the right, then while driving straight, it looks like the bars are turned slightly left, could it be my forks are messed up? or is it the upper portion of the fork clamps that could be off? how does one check the line up? thanks.
