Brought my bike in for the 24K service and it seemed to be running OK when I dropped it off. Got a call from the service guy who said there was a problem with the exhaust valve in the horizontal cylinder and that it was letting something like 80% of the combustion gasses through. He couldn't believe I hadn't noticed it. The net is I needed a new exhaust valve.
So my question is, what might have caused this? Sadly the bike has been outside under a cover this winter while our garage is being enlarged, but other than the last few weeks when the weather has been horrible, I've been riding it regularly (with no apparent change in power).
Is this a common problem? I haven't seen any posts on it, so I kind of doubt it, but wondering if the tech gurus can shed any light.
