Your bike is not fuel-injected and so cannot make use of a fuel injection adjustment unit or map. But it can make use of a jet kit.

Yeah, I've got one. I'll scan it and post it for you.

Hang on guys, this is the first time I've tried to post an image and so I've scanned it and saved it as a pdf document.[:M77]

I'll try again today and hopefully post it up in 4 hours or so.

Finally! Here you go guys.

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.

Anyway, the rpm per km/h are:

50kmh = 3,180rpm 125kmh = 7,950rpm
55 = 3,498 130 = 8,268
60 = 3,816 135 = 8,586
65 = 4,134 140 = 8,904
70 = 4,452 145 = 9,222
75 = 4,770 150 = 9,540
80 = 5,088 155 = 9,858
85 = 5,406 160 = 10,176
90 = 5,724 165 = 10,494
95 = 6,042 170 = 10,812
100 = 6,360 175 = 11,130
105 = 6,678 180 = 11,448
110 = 6,996 185 = 11,766
115 = 7,314 190 = 12,084
120 = 7,632 195 = 12,402
200 = 12,719

Sorry about the scrolling you have to do.


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.

Hope this graph helps you all.

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.
