2006 Harley Davidson introduced the Dyna motorcycles with a 6 speed transmission, and in 2007 the 6 speed was added across the board.
On the tranny.
Yes, you can as the 6 speed kit fits the gearbox. However, you should look closely into this issue since not everybody has been equally happy with the results.
Parts and accessories for Harley Davidson motorcycles, including models in the FXR line, can be found at a local Harley Davidson dealership. Racing and speed shops will also often carry these items.

2007 for the FLSTF Fatboy had a 6 speed transmission
Depends on the model. Mine will do around 120 mph.

Cropmaster gearbox takes 15 to 16 liters
Can't do it. The engine and transmission cases are different from 2002 to 2007. You would have to buy a cassette kit or complete transmission to upgrade your 2002 to a 6 speed.
Harley-Davidson has programmed a 110 mph speed limiter into the factory computer. I have yet to find a way around this problem but I have faith in the aftermarket.
If the harley has a four speed tran. One down, three up. Five speed, shift one down, four up.
