You may have a point about the compression.. I really need to put a gauge on it and see what it is.. soon. For what it's worth, it does feel pretty stout - about like kicking over a Honda 450 twin. My 200lb weight is a lot of help in this department.
Having worked on motorcycles over the years, I've gotten pretty good at kickstarting just about anything. When I do, I never straddle the bike - I always stand on the offside (right side of the bike) facing forward, and kick it over with my left leg. This assumes it has the kicker on the offside. If it's on the nearside, then I stand over there and kick with my right leg.
