I am pretty much using ram air on my KR. I made a fiberglass entry from the front of my cowling that has what is called a pre-filter attached. My oil for 20 some hrs. stays fairly clean. I like most of what power improvement I get etc. but here is what I don't like. I run a super posa and I think because of cool rushing air, the slide is harder to operate. I have to jerk the handle to get it to go close to idle. Also because of a more ramming of air, I must close the throttle farther than without ram air and I am hardly allowing any opening at all at idle. My idle screw is all the way out to allow the slide to almost close completely. Maybe this is not the real problem. I would like any suggestions Randy Clark, Salina, Ks ----- Original Message ----- From: "Gary Sprunger" <g_sprun...@msn.com> To: <kr...@mylist.net> Sent: Monday, May 30, 2005 6:19 PM Subject: Re: KR> Ram Air systems
