Thats some good power for that bike. My old bike was a 400 EX, bored to a 426.

Mine did 38 hp, but I also ran bigger cams and had some race porting.

I guess if it matters, stock 450r's are running 38 hp on their dyno. This just puts a bit of comparison as to what I ran compared to a stock 450. I think that is really good for a pretty mild machine. steve
