Hey everyone I am trying to get an idea for the jetting on my FCR. It is an 02 40mm fcr. Stock jetting is a 175 main and 45 pilot. the mods I have on my quad are 02crf cam, and the cheap HRC kit. I cut half of the airbox lid off, drilled the t, and removed the vacuum looking thing off. I also took the spark arrestor and baffle out. Does any have an idea what a good starting poing would be? I was thinking maybe a 180 main and a 48 pilot. Is that close? Thanks!
