A dyno is a great tool huh, but remember what was posted in the first thread about numbers being off are very common. I have heard of tests performed on the same machine and dyno by two diff operators one right after the other get completely diff results.
* Boy how fast everyone forgets who started the last post. Same operator, same temperature, and almost the same humidity (point off). Lets quit trying to pick apart the dyno and operator, lets start using the information for what its worth.
I do agree that the machine itself doesnt lie but dont forget there are other factors involved with the results.
* Again, if you want to beat this dead horse some more, please post it in the orginal Just got back from the Dyno. I would like to keep this one free of BS that can cloud peoples heads when your trying to show real data.
You seat of the pants test may not be all that off either since it appears that the carb did have an effect on the power curve which can be make the acceleration feel better or faster etc.
* Butt-O-Meter lied big time! because of it being too rich. What happens in a rich condition is the bike will not respond as fast as it should (not really noticeable by butt-o-meter), then once the engine starts to clear you get a surge of power. The butt-o-meter goes Damn! and you get a sense of real power. This is why Dyno tuning is so important to gain optimum HP for your money. If it cost you 165 bucks to tune your bike on a dyno with a wind band sampling the fuel you will not be dissapointed.
Good info and dont forget to post part III.
* Part 3, and so on will depend on the bashing, I will not spend hours debating dyno's, wideband, or mods. I will debate actual data and help others read a dyno properly.
Thanks for the reply
