my muffler broke after only 40hrs of use, the ''strap'' that runs above the exhaust tube and welds on to the actual muffler can broke at the muffler. looks to me like a poor design and/or bad welding. i'd assume the strap is there to act as a heat shield, now all it does is vibrate against the muffler and make a rattling noise. guess i'll be getting it into the shop over the winter and get that replaced under warranty, would it be a kawasaki thing or a wright issue? i'm using it too much right now i can't let it sit in the shop for a week before someone gets around to fixing it.
