Dealer claimed that 1st and 5th are square cut for strenght, while 2,3,4,and 6 are helical cut to mesh better. Bull. Since when is 5th gear a power gear?

From the AMA Site:

"The six-speed Cruise Drive transmission, which was introduced on the Dyna family in 2006, features gear ratios optimized to match the torque curve of the new Twin Cam 96/96B engines. The addition of a higher-ratio sixth gear reduces top-gear rpm by 11 percent, compared to the previous five-speed Big Twin transmission. At 75 mph, engine speed is reduced by 368 rpm, from 3227 rpm to 2859 rpm. Second through fourth gears have helical-cut teeth for quieter operation, and load carrying capacity has been increased significantly."
I hope I'm not the first to show you this and I hope your bike issues are resolved. Love mine but I guess I'm a lucky one.
