I sat on both back to back but couldnt take the Z400 for a rip it was sold. Ill keep my RAPTOR!

 

well I just got back from racing one. It had a yoshimura pipe, it was jetted with a k&n filter. The Z was also running pro wedges. I have a stock 02 raptor with sand skate II's. We were racing about 3 or 4 hundred yards. For the first four gears it was pretty close ei could pull away a little but it was tought. If he got a better start than me it was hard to catch up until fouth gear or so. I was very impressed with it. I still lke my raptor though.
