I have not had a chance to get back to the dyno, but I am fairly certain that I have higher number (sure feels like it) after making the carb adjustments indicated by the dyno run and the timing adjustments to address the knock. I am planning to send my carbs off to fast fred for the over size treatment in the next week or so (riding season appears to be done for me this year). Spring should yield some interesting numbers. Past conversations with fast fred indicate that 100hp should be doable for a 904. And that is what I would like to see.
