ZRX-1100 Dyno Numbers

Completely stock 1999 model

Note: these are true numbers off Dale's in-house dyno. The Holeshot compound is about 200 feet above sea level and the dyno room stays a constant temperature between 70-80° F. The above results were also achieved with Dale's tuning, which is a bonus.

Be aware that dynos, dyno operators, conditions and bikes can vary 3-4 hp, so this should only be used as a reference. Note: the same ZRX-1100 was used for all Dale's developement work and testing.

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.
