SV650 Dyno Charts

NOTE: These are true numbers measured on Dales in-house Dynojet 250 I dyno, with "Win Pep 7" Program, STD mode, Smoothing 5

The Holeshot compound is now at aprox. 4500 feet above sea level here in NV, and is down about 3 to 5 HP from our old location in CA. Dale uses his dyno as a measuring tool for development and testing only.

Be aware that different dynos, dyno operators, conditions and bikes can vary 3-8 HP, so this should only be used as a reference for before and after results.

Dale also tested slightly larger #42 pilot jets as well as many other settings. We were able to squeeze out about to 2 to 3 more hp from the ZZR with the larger pilot jets installed and made the best pull off 143.9 hp. But Dales road testing showed a drop in fuel mileage, about 37 to 38 mpg on the freeway at steady cruise. Also the idle is smoother with the stock pilot jets as well. For only 2 hp or so Dale decided to only recommend shimming the needles and re-adjust the fuel screws. The ZZR runs butter smooth with this simple adjustment and is plenty fast. But if you don't mind the above and your a power junky you may want to try the #42 pilots jets also.
