Johnny, please can you give your expert opinion on the attached Dyno run,
I think the problem with the A/F is the scale of the graph....???
Cheers mate Del

the fuel could be added to but..............
it has to do with if the o2 sensor is reading correctly
I have had some that read wrong had to tune bikes at 15:1 due to the O2 sensor was off now I keep extras.
also how above sealevel are you? more than 500 feet?
pressure is kinda werid on the correction factors

 

[delboy]

At about 200 feet mate, if that helps..............

 

[Johnnycheese]

correction factors are off a bit but if the 02 is correct then you need a bit more fuel

Thanks John
