20:1 just seems really rich and I've always ran 80wt in my bikes. This is my first Honda I guess it's a different breed.

You'd be fine with 32:1 or 40:1 depending on the oil. 20:1 is going to be really rich.
I recommend Pro Honda 10W40 for the transmission, but you can find a number of oils now that are formulated for motorcycle transmissions. You don't need to use 80W.

Like Mark said, 20:1 is way too rich. Most synthetic pre-mixes today are designed to run at 40:1 or leaner. You do not have to have 80W in the gearbox. The Honda stuff is good, and Motul is great too, have been using it for years.
