Confused Dyno run

Re: Fuel consumption

Right wrist and/or AFR being too rich.

Re: Fuel consumption

You said it was dyno'd. Do you have the chart with the AFR graph?

Re: Fuel consumption

Read previous thread 'Confused Dyno Run" for Dyno sheets.. Note also that both tests were done on country roads at an average of 100 kmh.
Cheers.

Re: Fuel consumption

Sounds like you're asking for help on the same issue in the other thread. I'd follow the advice already given by Dolt and find a new tuner.

Re: Fuel consumption

Merged "confused dyno run" and "poor fuel consumption" to keep all the issue related in the same thread.

Had an Andrews EV27 cam fitted and Dyno tuned again and it came up with 65.33 HP and 71.67 of Torque. I would have thought that with all the work it would have put out a bit more. Any suggestions?
Cheers.

No suggestions but two things stand out.

1. 200ccp is way to high for a stock bore/stroke 1340 motor; something isn't right.

2. I still question your tuners capability.

I have attached a chart for a stock bore/stroke 1340 motor, not head work, static CR at 8.5:1 with a set of EV46 cams, stock head pipes, HD slipons, timing set at 32*BTDC, stock Keihin CV carb, SE 6000 street module iginition and SE dual fire coil; pretty plain Jane configuration. Note the better numbers and the flat torque curve.

Thanks for that info, dolt. Very interesting.
Cheers.
