Tinbanger,
Outstanding!! Just another example of the great reliability of these models.
Like Velosapiens I have a bit more than double that, I'm right at 212 hours and 4650 miles.
At 180 hours I replaced the cam followers, as the exhaust side valve lash started increasing, and I found the exhaust side cam follower was trashed, I was lucky it hadn't failed. I think that the common knowledge on the cam followers is that @ 150 hours you could be on borrowed time. If I had it to do over again I definitely would have pulled the rocker box at say 130 hours and checked them, or just replaced them. These are definitely worth keeping an eye. As they start to fail, the hardened bits of material from the bearings can and will end up in between the opposite roller and the cam lobes. This cause the wheel to skid on the cam lobe until the piece dislodges itself, and this will leave radial scratches in the cam lobes, thereby compromising the hard facing. This is what happend to me, and I was lucky the damage, while a bit ugly, was not serious enough to replace the cam.
Another thing to keep in mind is the valve lash is normally decreasing due to wear, at the same time the cam follwers are wearing out, kind of canceling each other out to some extent once you get up in the hours. So, you really can't tell how worn they are unless you pull the rocker box and roll them with your finger to see if they're getting gritty, or if there is any yaw type of play in the bearing.
When I pulled the rocker box I also checked the cam chain tensioner and it had about 4 clicks left so I changed the cam chain at that time too.
The cam bearings were still good, but, had just a little bit of noticeable wear so I changed them too. Just to be on the safe side.
And, like you, I change my oil often.
Unless something starts making noise, or I start to see lot' of metal on the drian plug magnet, I figure I will wait till 300 hours to tear it down.
