The bike feels very strong through its rev range now,maybe its me trying to justfy the $$ spent but she does feel very good,all in all very happy  with the mods so far.My 900 has done 2200 klm cheers |
Ok, let me see if I got this straight. According to the dyno tech your bike was setup running rich with the PCIII. He made appropriate adjustments to lean the air/fuel and the run you posted was the results of the adjustments. Is that correct? So now your bike is pretty much at the correct air/fuel ratio? Over here they do a corrected and uncorrected run. Corrected compensates for elevation, temperature etc. Uncorrected is real world results for your bike at that given time and place. If it does not say you might want to call and ask. My uncorrected results were an additional 1 hp and ft/lb of torque. I posted on this thread some factors that affect dyno results, i.e. a bike with 6,000 miles compared to a bike with 1,000 may show a 10% increase in power. Running synthetic oil can improve the performance 1-3%. Also a lower drive ratio can change the output (adding a Scootworks pulley for instance). Here is a link that I also posted in this thread that talks about some of these factors.

Again thanks for posting. In this thread we now have a dyno for a stock VN900, just a BAK (& Scootworks pulley), and yours with BAK/EFI/pipes. It gives folks something to think about.
