Why is the engine braking so modest?

- Compression ratio on my Stage 4 103 Breakout is higher (the difference is so great that it was actually RECOMMENDED that the VTX be run on 89 octane fuel)
- gearing IS taller on my Breakout
- Idle speed is virtually identical (1000 on Breakout versus 950 on VTX)
- The Breakout is lighter in weight by over 75 lb (100 lb if both bikes were stock, but the VTX had been lightened by about 25 lb)
So, the Breakout has:
- 1 factor that reduces engine braking (taller gearing)
- 1 factor that is neutral (idle speed)
- 2 factors that would predict MORE engine braking (higher compression, lighter weight)
And, here is a final zinger: The flywheel assembly on the VTX is the heaviest one that Honda has ever put in a motorcycle.
Intriguing, isn't it?

On the other hand, my rear wheel is undoubtedly heavier than the one on the Honda. I have the HD chrome Turbine wheel set, and that Turbine wheel even LOOKS heavy! The heavier rear wheel would make the Breakout more resistant to changing engine rpm with the throttle closed.
