swjohnsey,
Losing the extra power the ram air provides is not important to me, this is mostly an intown play bike. The fastest I expect to go on it is typical freeway speeds in my area, 70-80 mph.
But, wouldn't Kawasaki have sized the mains and needle to take advantage of the increased airflow that ram air would provide? If they sized them for regular atmospheric intake and then crammed more air in through the ram air, it would go lean and start melting things. Or is it a function of slide lift? Is is set up so that at redline in first, where you don't get much help from the ram, the slide isn't open as much as it would be at redline in sixth where you need more fuel due to the fact you're getting more air? The difference in those two extremes is the amount of intake pressure on the underside of the slide diaphram and the amount that the needle is raised. You could be right, I may not need to rejet because its a self correcting system. Only one way to find out.
Still, has anybody out there done this? Lemme know. Thanks.
