Pro's
Runs cooler
fuel is cheaper
at WOT (IMO) seems to be more consistant than gas
torque is lower in the RPM (most of the time)
Cons
starting can be an issue (put a primer set up on it)
fuel system maintence- run klots or another lube or drain the system every weekend and WD40 everything
Oh and it is great for finding evey little nick and cut on your hands (LOL)
