Well I have had my bike for about a month and a half, and it has almost destroyed the chain. The other day I noticed it was slack so I go to feel it, and it has a lot of play side to side. I lube it before every ride, is this just something that big bore 4 strokes have a problem with? I have been lugging it quite a bit, enough to where I can here the chain rattling, but I wouldnt think that that could cause to to wear out like it has. Any knowledge on this guys?
