SOURCE: 2006 road king engine heat

I don't see how oil can cause an overheating problem. I think the service tech was screwing with the fuel/ignition map when the bike was on the dyno. Is it a F.I. engine? Lean mixture or retarded/over advanced timing will cause this, among other things. The dealer may have to eat the cost of repair if you can prove they caused the problem. An air cooled engine that overheats is gonna self destruct!! Get it checked out NOW.

SOURCE: valve noise 2006 road king

Hello redevil67...This is normal for the HD engine, it going to have valve train, top end noise at some point, some as early as 2000 miles. If you take it to the dealer they will try to sell you on worn tappets...key word here SELL..I've seen this many times, dealer replaces componets, 2000 miles later the noise returns.
These are hydraulic valves and as you probably know they operate at zero lash. Personaly, i feel that the problem is that the cams are not hardened properly or machined incorrectly.. When the leading edge of the cam lobes wear to a strange profile it tends to snap the lifter up in the lifter bore. This causes the rest of the valve train to rattle. You hear the noise on top but the culprit makin it, is the cams..Many chose to go with an aftermarket cam, such as an andrews...Another suggestion, is to switch oils. Don't know what you are useing now, but i'm not a fan of dino oil. As the temperature builds the more an oil is stressed. Lucas full synthetic 20w-50 or Mobil1 15w-50 are both excellent for anti-wear and long term protection.
I hope this helps, please rate me a fixya and good luck with your bike.
