I know a few wont agree, but i've seen this, a guy had some runs at Matts dyno on his R1, well happy with the figures, moved down south, had it dynoed and got completely different readings, in fact much lower, on another dyno you might see 300, or more, plus you have air temp, and lots of other factors, you know it pulls well, thats the main thing. :thumb:</blockquote>
