I'm not trying to create a pissing competion here but I'm curious to know what others have achieved. I just had my 06 450 r dyno tuned and got 52.4 hp. Faster heads extreme ported 08 head 12.5:1 piston stock bore Stage 1 hot cams cam I thought it was pretty good with the nobby on. I know a lot of dynos can read different. Russ told me that the best he had seen from a carbed crf was 55 on his dyno. Those of you who chance to be in perth may know Russ at Dynotime he has a good reputation for suspension and dyno tuning.
