The photo shows the first chart with the weather conditions included.

The temperatures are within 6 degrees of each other. This is critical for Dale's testing to achieve true repeatabiliy.
Dyno Chart
The above chart shows 4 dyno pulls in a row of Dale's same FZ1 with the complete Holeshot Stage 2 Jetting Kit and full 4-1 Header System installed.

Dale's second FZ1 test bike belonging to local customer (Pep).

Note! This is a high mileage bike with 30K miles on the clock. Temperature was in the 80 degree range during this testing. Even in non-ideal conditions the 5 hp+ gain and improved torque was still achieved.

Run 018 (Red Line)

Note: These are true numbers measured on Dales in-house Dynojet 250 I Dynamometer with "Win Pep 7" program while still at our location in CA.

The Holeshot compound at the time was about 200 feet above sea level and the dyno room kept at a constant temperature as possible. These results were also achieved with Dales tuning, which is a bonus. Dale uses his dyno as a measuring tool for development and testing only.

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