Thanks again to Dave and Brad.
But what I am really looking for, (and I must have poor search ability), is the specific difference between a FI cam and a Carb cam and why a FI cam does not send the right "signal" to the Carb..
I did find while searching that supposedly the FI cam closes the valve sooner than a normal carb cam causing some of the air/fuel charge to get left behind in the port.
I would guess that the reasoning behind closing the valve sooner was to increase the low to mid torque numbers by increasing the dynamic compression down low.
If that's the case, that definately hurts carb performance down low (ie. Rich) and limits it on the top end (low dynamic compression).
I am curious if it could be helped a bit by using a higher ratio rocker arm causing more lift which might alleviate the early closing.
Also, who else besides Pauter makes ratio rockers for the Type 4?
I am assuming that Raby just uses the stock ones.
Anybody know??
Thanks again for all of your opinions; that's what it's all about!!
