The recoil was the giveaway, I saw it earlier today. I had a 1042cc 4 cyl. twin rotary valve rotax open mod sled, it was 280hp@9200rpm. Was way,way to scary for me in 500ft of bumpy grass. 300lb sled and all that power with a 121" track, no thanx, I am not in for death ride 2000. Magic, did ya build another engine?? what kind of pipes did ya have on your 780??
