but you guys tell me what you tink about the numbers i know more about cars on the dyno not bikes???


the peak HP was 57
54% humidity

but the a/f ratio had a dip at the start to14.7:1 then massively riched up to 17:1 then slowy dipped to 16:1 right in the middle then back up to 17.7:1 more or less it sounds rich to me but i would like your input? carts good but thouse guys were just tryin to sell me the PCIII for 400 bucks

Slowhound is right, you are running lean. A/F should be in the neighborhood of 13:1.

Do you have any modifications done to your bike? You need sometime of ECU upgrade or remapping if you have a fuel injected bike with modifications or it will run way to lean.

Thats exactly what its for. Bring it back for a dyno tune when you get it installed and your bike will be dialed in.

Currently I have the SE stage 1 air cleaner with v&h short shots with a PCIII and it runs great but it was dialed in on the dyno. I want to change some things now with not having to save up all the money for the whole set-up I want but I'm afraid just something simple and I will have to bring it back to the dyno and thats not cheap. I wish I could have some other alternatives.
