Yesterday I picked up my '02 400 MXC from Alan Randt at Enduro Engineering. Alan had put the EE450 kit in my bike as well as the Mike Lafferty Big Gun exhaust system. Funny when I got the bike home I also received the new Dirt Rider with the EE 450 kitted Mike Lafferty bike in it that was used in their 24 hour test. My first impression is that the bike is everything they said it would be and possibly more. It was about 30 degrees out when I started it, starting was the same as when it was a 400, very easy. The bike however, although just slightly louder had a very different tone. I rode the bike only briefly due to the weather and the time of day but can say that the new power is AWESOME. The power band builds like it did when it was a 400, just builds quicker and there is much, much more of it all through the powerband. During my very brief ride the front wheel could easily be lofted in the first four gears and it got there very quickly. Can't wait to get it in the woods this weekend. Will post a longer more complete report after my ride!!!!!!!!
