The Bimotion menu consists of 10 choices. They are Time Area Targets, Piston Controlled Intake, Exhaust, Transfer, Expansion Chamber, Cylinder head, Piston Load/Acceleration, Gearing and Road Loads, Yamaha Energy Induction System (YEIS) and Quit. To start the program I choose Time Area targets. I entered the basic engine parameters (66.5 mm bore x 57 mm stroke) and target HP (17 stock and 25 HP, 29 HP modified) and peak RPM that maximum HP will be achieved. The High Output version of this engine in the far right hand column is designed using the long rod (115 mm) and has a bore and stroke that measures 68 x 57 for a displacement of 207 cc^3. Bimotion calculated the TA Targets as follows:
Bimotion 2.1 is more well rounded than the earlier versions I tried. The squish velocity feature is very welcome and necessary. The boost bottle program is also very interesting and different than the program from TSR. More to come - Rick |
