I have a 2002 Cannibal, K&N air filter with outerwears, gutted stock pipe, no engine modifications, stock gearing, sand shark 8 paddle rear tires, stock front tires, running moto/speed map, leaned out the injector flow rate just a tad.

My wife has a 2003 Cannibal, stock engine, stock pipe, stock gearing, K&N air filter with outerwears, sand star 8 paddle tires, moto/speed map.

My brother-in-law has a 2003 Cannibal, stock engine, stock gearing, K&N, outerwear, sand star 8 paddles, HMF pipe and one of the hybrid motorcycle maps in it, I can't remember which.

We ride at Sand Mountain, Nevada. It is desert sand with the main drag hill being a 500-600 foot elevation climb from bottom to top. On this hill, it doesn't really matter how you start, the fastest bike will always end up winning because the hill is so long. All three of our Cannibals are about the same on power, the HMF gives some good low end, but top end seems to be about the same.

I am not into drag racing, it just seems to break expensive stuff, I prefer to play on my bike, ride wheelies, slide, jump, and get my arms ripped off by impressive acceleration. I do however, once in a while give it a run up the drag hill for comparison purposes.

We have run our Cannondales against a lot of different bikes up there, smoking most of the four strokes. Some of the built raptors are pretty fast, but can't stay with us on the top of the hill, they have to drop a gear. I just sold a Banshee that I built to a friend, and it is one bike that our dales haven't been able to beat yet. It is bored all the way out, vito's power pistons, I ported the heads intake and exhaust, boyeson dual stage reeds, welded crank, shaved head etc.. etc... all the goodies. The Dales obviously have killer low end and kill the banshee on the holeshot, through the whoops and about 2/3 up the hill they're neck and neck but once the banshee gets into fourth, it just leaves and will get us by about three bike lengths at the top.

Now about the Yamaha YFZ450's, the only four stroke I've raced that gives competition. I have two friends with 2004 YFZ's and they have friends with two YFZ's. The least modified has the GYT-R pipe, no competition, it is like racing a 400ex. One of them has the Yoshi pipe, cam, jetting, K&N and whatever he has done to it recently. The others have other forms of modification not worth discussing. The fastest one runs the sand skate 2, 8 paddle tires.

Anyways, a typical drag race against these bikes yields a fairly even race until the top half of the hill, all of the YFZ's begin to fatigue and have to drop a gear like the Raptor and our dales consistently beat them by about 1-2 bike lengths. I have never raced a YFZ in the dirt or pavement or any other surface. I have raced with a speed out there that was set up for MX, geared very high and he was getting beat by Raptors and Predators, I was killing him. The YFZ is a great bike, and makes great power. It doesn't have an aluminum frame, fuel injection, or American craftsmanship. Maybe it hasn't had as many problems either, but my 2002 Cannondale Cannibal has given me about 100 hours, no trouble.
