My CBR600 dyno graph
I didnt think it was that bad at all, considering it is 10 years old,
has 34,000 miles on the clock, has been caned to fook on numerous trackdays and desperately needs a full service. Honda claimed 100bhp at the crank when this model was new, mine still makes 95.13bhp at the rear wheel.  There's some cleaning up of the fuel/air mixture needed in the midrange, which can be dialled out by dropping the needles down one notch and cleaning the K+N air filter that's fitted. The fuel/air ratio in the midrange won't improve the overall bhp figure but it will improve the driveability and torque available from 6000 upwards. Dropping the needles is something I can do when I have it apart in a few days to service it. I'm happy enough with that graph though. |

Re: My CBR600 dyno graph
Good old Honda. Is the line across the middle the torque curve? Flat like a twin.

Re: My CBR600 dyno graph
Yes, the flat line is the torque curve...or some old person in a red shirt has just died on Casualty.

Re: My CBR600 dyno graph
I wouldn't bother messing with that, it's nigh on perfectly smooth!

Re: My CBR600 dyno graph
There's slight dips in the power curve that correspond directly with the large dips in the fuel/air mixture graph. Sorting that out will make it even smoother and improve the midrange power and torque curves. Call me fussy, but I want it perfect if I can possibly get that.

Re: My CBR600 dyno graph
I'd love to have mine dynoed (approx 30k miles) but only out of curiosity. And then hand copies out to every 'Blade, R1, GSXR, 911 (delete as appropriate) that I pass on track
(Probably only to be handed an even smaller one back off a CB500/supermoto/125 rider who has anihilated me!).

Re: My CBR600 dyno graph
Cool 95bhp is very respecatable at the rear!

Re: My CBR600 dyno graph
Wonder how much my Kwak makes now?
Probably less than an SV650.
