UPDATE:
Well, we were able to line up the following bikes and race up Oldsmobile a few times:
1. 2005 Raptor -stock
2. 2005 Predator -stock
3. 2005 Yamaha 450 -stock
4. 2005 Yamaha 450 with a slip-on and jet kit
5. 2003 Banshee ALLL tricked out
The Raptor was on its first trip out and barely broken in so...
The results were what I expected after talking to everyone about the new 450s
My stock Predator Did gett beat by the stock 450, but it was like one bike length at the top everytime so Im alright with that.

The piped 450 got me by about 3 bikes, damnit
The tricked out banshee was a screamer of course!
Bottom line: I gotta get intake, exhaust and carb. work!
