I put the Triumph carbon can on 11000 miles ago, it started leaking from the front seam after about 7000 miles service, dealer would not warranty, doesn't affect anything but looks and having to clean extra surfaces. Definately looking at Akropovic next time. Might could drool some Devcon epoxy around the seam and let it set up or use high temp duct tape for the real racer look..(kidding) Our cans were obviously mfg.ed the day after a good football game....
