These two runs were 4th gear roll ons and we couldn't be bothered hooking the dyno up to the coils, so the "X" axis is in km/h rather than rpm.
I've calculated the rpm for each km/h increment for you (and me) so it is easier to see what the engine is doing at what revs.
The graph is shown with 5km/h increments (shown by a dot on the graph) starting from 50km/h and labeled at every 25km/h.
The "Y" axis goes up in 2hp increments.
On the run with 7,400km on the bike it peaks at around 86hp at the wheel. This particular dyno gives low readings due to the correction factors used by the operator. To give an idea of how much power this bike made, at the time of the run, the only 600 that had made more power on this dyno was a race prepped CBR600.
The second run was done with 38,756km on it to get a baseline just before I fitted a full Muzzy race system. It shows around 80hp at the wheel. I don't know if this is due to age or the bike being a bit out of tune. I really don't think it was due to age though. The bike is now standard again except for a 43t rear sprocket and still lifts the front wheel in first under acceleration alone, having now done 183,000km!
Also, the graph only goes up to about 12,700rpm because the run was made using the bike's tacho instead of the dyno's and the bike's tacho reads about 1,000 rpm high at redline. Most bikes are like this, or were anyway. I'm not sure about newer bikes.
In addition I have calculated (at some time in the past) the torque curve and thrust curves in each gear for this bike from this dyno graph. If you are interested in them I can e-mail them to you. I can't post it here because it's in an Excel spreadsheet and I can't link to them because I haven't set up a website yet.
I also have graphs of a run through the gears at 7,400km with the bike completely stock, and a 4th gear roll on with the Muzzy system before re-jetting.
Actually, the main difference between the stock exhaust and the Muzzy system is that with the Muzzy system the power doesn't flatten out at the top end, it keeps building and puts an extra 5hp on the top end before re-jetting.
