thanx steve. my cousin just picked one up,were waiting 2 see how it runs. my freind has a o9 xfire r 1000 with the deeper lug sno pro track on it and it will do 116 mph in no time on the rader gun, it may get close 2 120 mph with the 1 inch track on it.this sled is very quick on quarter mile. im starting 2 think the 2 stroke is still the champ.
