So a couple months ago, or maybe around May, I performed all of the CCC mods, except for the R's cam. Recently I bought a Dr.D ehaust system, but that didn't recommend any jetting changes, so I left my jetting alone. However, after I performed these mods, my bike has always had a horrible bog as soon as I cranked the throttle from low RPMs... Here's how everything, after some tinkering (but to no avail), is set up: 40 Pilot 150 Main Needle - 5th position from top (1 LOWER than recommended) 55 leak jet Pilot Screw about 1 1/2 turns out Air Filter Backfire Screen IN (stock airfilter) Air Filter box cut to Honda's specifications (on the line) I ride usually in 60-75 degree weather at approx. 2000-2500 ft I took out the carb when I did all these mods, and I also removed the smog pump (CA model). The bike runs great other than that horrible bog... Any ideas? I'm truly stumped, especially after tinkering for 3 months but having nothing change for the better.
