Yamaha FZ1 Header / Stage 2 Jetting Dyno Charts

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.

Note: These are true numbers measured on Dales in-house Dynojet 250 I Dynamometer with "Win Pep 7" program.

The Holeshot compound is about 200 feet above sea level and the dyno room stays at a constant temperature between 68-74° F. 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, conditions and bikes can vary 3-8 hp, so this should only be used as a reference for before and after results.
