Yah I would agree it's built right, I dont know if he ran 3.8's on it or not I didnt ask him what his best times were. The owner of the bike Brett, was very nice and seemed like a good guy. I am not really a 4 stroke fan but I have to be honest that bike impressed me for sure, it's a 60fting mofo for sure. That video was from Busco Beach and we were racing in the 4.0 index class, and from what I can tell the track was slow, so I wouldnt doubt it if he has run 3.8's. The jockey is one hell of a rider and his reaction times were great.
