Dyno questions?
does the weight of the rider and the gearing affect dyno numbers? seems in my uneducated mind that it would have to?
|
Not really, it effects performance, but not engine output. Now gearing matters with how accurate the dyno's measurement is, but the tach led is suppose to allow the dyno software to account for any gear ratio.
|
that is a debated topic of dynojet vs flowjet numbers.
It won't but that is ONE of the many points that makes the above differences. |
Gearing yes (possibly, depending on if you can get a tach signal)
Rider weight, no. There should be no rider weight on the bike when running on the dyno. Rider should stand straddling the bike. |

he's straddling it, but not really putting any weight on the seat. http://i203.photobucket.com/albums/a...h_buell007.jpg |
u know-i was lying, cuz thats your bike, and i watched most of the 1st one i think. oops lol
in person, always feets on the pegs tho-could just be the one side im standing on tho |

though one foot on the peg shouldn't affect that much, but it could throw it off. just like if you put the tire back on the drum it will give a low reading, and forward on the drum will give a high reading. It's gotta be centered to be accurate. And yup, that's mine. Bitch ran good that night :dthumb: |
Should not matter as long as its the same each time. In other words don't let the fat guy do one pull and the thin guy do the next pull. Always go out of your way to make each run the same. Check and adjust things like tire pressure and engine temperature.
The numbers don't really matter much its the difference from the stock pull to the modified pull. You should not compare dyno umbers with a different dyno. P.S. I disagree with the standing over the bike as you can not properly work the controls and if needed for some emergency the rear brake would be hard to apply quickly. Not to mention a all gear run would be tough and they can help find a float level or starvation problem. |
