Pobly. There use to be around 7 warriors & 3-4 400's in S.E. Ky. in the late 90's & to about '03 & it gradually went down when the new 450's come around. It's hard to compete with 50hp on engine, to around that with NOS for the warrior. If there would have been some 400's, which there was about 3-4 of them at one time, but they couldn't out run the warriors, unless the rider was 150lb. or they cut a good light on the tree. They built them to 565's w/NOS & then they would beat us some. If the track owners would have limited the cc's to 500cc's on both engines, then there would probably be a bunch still running. My bud built a Mojave 250 with a stroker engine & all the works & he runs with the warriors. Me & him both weigh about the same & it was ever who got the light that won. I'm gonna get back in it this yr. probably, if I get back to work, so I can get the engine work done.
