Engine Tuning Cautions - BOMBARDIER 1996 Ski-doo MX Z440 Handbook

ENGINE TUNING CAUTIONS

Here are a few items to keep in mind when working with your engine.
1. If you are in stock classes, know what adjustments are legal.
2. Modifications to the power curve of an engine will require recalibration of the transmission.
3. The lower the RPM at which you can generate the torque you need, the higher the percentage of
that power that will reach the track.
4. Sloppy engine modification usually results in less power than you had stock.
5. Follow the assembly and disassembly procedures outlined in the appropriate Shop Manual:
