Ok, I have a couple of questions on my fcr that I recently put on my 05 450r. First of all I had the "bog" that alot of the FCR's had. I installed the quick shot and it almost cured it, and planning to put a smaller leak jet in. So no problem there really, as it is virtually gone.
My big question is the quad seemed to run great, but the top end pull from the old carb just didn't seem to be there. My jetting right now is at 168 main, 45 pilot, 55 leak, 1 3/4 turns fuel screw, NYCQ needle 4th clip. I have HRC Cam, Rossier short can, K&N, EHS lid, and dynatech. I know what I need to do to get rid of the bog, and everything from off idle to mid-range feels great, but the top end seems to be lacking. It doesn't sputter or anything, just doesn't seem to rev out like it should or how I want it to, especially in a small hill climb.
I know I probably need to change the main jet, but I am not sure if I should go richer or leaner. Like I said there is no bog or sputter, just feels like it could be better on the top end. Thanks in advance for the help!
