Feel free to ask anything you need. Hope I can help.
Regarding the kawi race cams, I had one (int.) and it did not made a significant difference over stock.
I know that Garth achieved very good results with it in combination with a high velocity style head porting.
This means that, with the stock porting, the cylinders begin to discharge themselves at some point from BDC to the intake valve closing point.
Head velocity porting increases the intake charge velocity by reducing the diameter of a section of the intake ports (ventury effect). The increased velocity helps avoid the cylinders discharge at the end of the intake cycle.
Having to reduce the flowing capability of a head to make it work just means something´s wrong with that camshaft design, and related to the whole engine breathing process and components; from the beggining of the ram duct to the outlet of the exhaust pipe.
Kawi charged $84 for that int. cam for years, and that has to mean something..
