I went to the Raptor rally this yr at Florence Oregon, and Rocket factory, Rooster, etc had some of their fastest creations for 897 and 900+ cc powered raptors. There were a few very fast honda singles that came as well to compete. We ran the Hill and then decided to head down to the flats. There was a 7 mil cub on alky and a 10 mil cub on gas....no raptors beat them when I was there. A rotax powered Honda ran very well too, but Randall's 10 mil cub and Geoff's 7 mil cub beat everything they ran againest. At Dunefest, the fastest single pass was from a Puma powered Honda, 4.20. I will say, the DS's are making some serious noise for single's however.
