VR2 on the road dyno run

The following dyno run was done on a closed course in 4th gear running from 4000 rpm to 10 050rpm.
The figures read out will not be the same as those obtained from stationary dynamometers as this dyno is done through the measure of the G forces with the use of accelerometers. However I'll just be using the general trend of the torque and hp curves to determine the state of tune the engine is currently in. There is one significant dip in the power between 8000rpm to 9000rpm and the lack of torque in that range seems to suggest that the engine is running slightly leaner in that rpm range. Adjustments will be made soon and a similar run will be conducted again to see if any improvements are made.


This graph shows the G force measured by the accelerometer. It's gradient tell how strong the engine is pulling and towards the end of the run when the engine runs out of juice the curve will dwindle down. A similar dip can be observed in the time period where the rpm is between 8000rpm to 9000rpm. Something needs to be done.

More updates to come as I do more testing on the bike with the VR2. Stay tuned.
