Pete is correct.His quad is high for some reason and believe it or not I give alot of that credit to Arimoks and his X440speed map.Also the head on this one has good factory porting all the seats and ports are lined up nicely.Also Sandstorm maybe yours would have dynoed more if time were taken to map the quad like both Arimoks and I did on Petes.
Did it have the short stack air horn.People claimed to 2-4 hp from that and 450 piston +2hp.Sounds about right.Remeber the $300 ace air box that was just a short stack bike air horn.Number look like they add up.
That explains that. Did atk switch the stacks out or did you? Thats still dam good for not touching the engine. I would figure the piston and bike stack to get it up to 43 to 44 hp.
I believe Arimoks switched the stack as it was originally a cannondale and he received a crate ATK motor for it. So anything outside the motor is cannondale, motor is ATK.
Unbelievable!Could tell we had something about 5th or 6th run she reved out real quick.Nothing was changed except those cams and a really bent axle.Way to go Pete
