Idle of 4 stroke is much more better than 2 stroke as well as transition, I never used 4 stroke, don't own, but in future I would naturally cost is killing. Only the flaw in 4 stroke I see is the front valves, they seem pretty susceptiple in the case of crash, chances are very rare of saving a 4 stroke from being damaged where as 2 strokes have more chances of not being damaged at the time of crash.
