JJ,

Thank you for the feedback.

I will make changes to my web page to display the dyno charts and a better explnation of what they do.

Advancing the cam timing by the 9 degrees moves the power and torque curves 800 to 1000 rpm lower in the rev range dependant on the model.

After installing the sprockets and you look at the dyno graphs overlayed, essentially what you see is the torque produced at 3,000 rpm now is what was produced at the 3,800 to 4,000 rpm of the stock motor.

This gives the same throttle response and accelleration for less throttle opening and revs throughout the rpm range.

This in itself allows for the use of one gear higher for most riding and less need to downshift for overtaking solo or two up.
