My orange bike. I swapped out the sprockets for a 13/44 and planned on running 21" haulers but never got around to it. With the 20" haulers 1st gear gets the grab bar in the sand, and 2nd gear is good, but if the sand is a bit powdery I can rap it up and dump it in 3rd and it won't fall on its face. If the sand is more coarse, I can't always get a 3rd gear start without it stalling about 10 feet after I launch.
If I can get some new 21" tires for it, I'll be able to start in 2nd like a normal person.
On the F4i...its isn't ready to start yet....
