I am running a yoshimura full system, PC III, and BMC Race filter on 93 octane pump gas. I had a problem with the carbon fiber canister burning through the expoxy (yoshimura warranteed the issue) so I put the bike on the dyno to see if it was running too lean, and according to the guy who did the tuning it was actually to rich in a few place. I was hoping that you all could look at the before and after results and tell me if everything looks like its supposed to. I did gain a few HP and torque:biggrin, but I'm not a dyno expert so I'm looking for feedback.
Thanks

the numbers are low, but not the overall gain and that dyno might just be a bit on the low side. Every dyno is a bit different and another dyno might show him at 180rwhp. The gain is what matters most and then the a/f ratio. Looks pretty smooth though and you surely got a gain.

The original 157 hp was the fuel moto map that I recieved with the full system, pcIII, and airfilter. The 162 was after some adjustment to the map especially on the top end. The guy who dyno'd it said that the only way to get the stock motor up into the 170's was to run VP racing fuel, and I can't see paying $125 for 5 gallons of MR9. The ride definately feels smoother, but I was expecting a lot more. Hopefully his dyno just reads on the conservative side!

Well, he doesn't know what he's talking about. That is not true at all for the K7/K8. Never been a fan of the blue, but yours looks nice.

My K7 with LeoVince factory slip-on,Pc usb and custom map..did a dyno pull a few months prior just to see were the bike was stock and it was free:biggrin. I would look for another tuner just to get a better idea were you stand...from what I've been told the correction factor most used is SAE...my K7 using the STD cf came out to be a little over 170 at the tire. Oh, the baffle was out while tuning so peak will most likely be lower with it installed but I was looking for a little more in the mid-range and better throttle response.

Dang Look at the temp when the dyno was ran. 78-76 degress could be part of the readings.

I know soe guys like dale walker that run his dyno in a temp controlled room. ideal temp's I think is in the 60's for more HP

btw I have the same bike with the same system awaiting install and Im not real concerned about the HP because its more than I ever need anyways just wanted to lose some weight freshen it up!

Id be looking to fill that dip in the torque curve between 5000 and 7500rpm.
An A/F curve would be useful if youre worried about it being too lean.

Putty: Whats the max HP numbers when you remove the spikes, I cant read the scale. I think a stock 05 zx10r made the most HP of all the bikes (all stock or minor mods) at a dyno day i was at last year.
