Has anyone managed to kill a 708 yet? Mine died on me today. just out riding and it sputtered then died. towed it home pulled plug. and it looks like someone beat it with a hammer... Has anyone had good experience with Yamaha warranty?
Sounds like something was dropped in there at assembly or on the service. The only other options that I know of are a dropped valve or I have seen a piston crack and start to come apart at the top.That's great news, but what was the object??? There are only so many "things" that can get into a combustion chamber without dropping stuff in, non-magnetic sounds like aluminium, would luv to know what it was & where it came from for future reference.
