I for one am not out to conserve energy. Im out to keep my bike running right in 100* temps. + the new energy conserving oils are very weak in the additive packages.

My '07 manual doesn't recommend it, per se, but lists it as an alternative if the lowest temperatures encountered will be 60°F or higher.
The most wear the engine encounters is starting when cold, and this is the main reason all MC and auto mfrs. list a multi-viscosity oil as the primary application. A 20w50 will protect like a 50-wt. while flowing like a 20-wt. when cold, so you have the cold-start protection with the benefits of a 50-wt. when hot.

Harleys are roller bearing motors and you don't have to worry about bearing to bearing scuffing when the motor is cold as they are touching each other as they should be. The ONLY drawback running a strait weight oil is it will take a little longer to get the oil up to operating temp and thats it.

50w dino in the summer. Been doing it for years. Get a little quieter valvetrain as well.
