Okay, I just finished installing my 450 cam. The bike rips in the mid range to top end. No knocking, or strange noises. Kicks over first kick when hot. BUT, I noticed this horrendous bog from about 1/4 throttle on up. I started off with stock main, needle clip one up from stock, with a 40 pilot. Played with the AC pump, BK mod screw, fuel screw, idle, etc. Bog went away somewhat, but out of tight turns and up big jump faces, I wasn't too confident with the response. When cruising in 2nd gear at 1/8 throttle, I peg it and it goes "BO-Waah". When it kicks into the midrange it hauls. So, after all of this, I went to a 45 pilot, readjusted the AC pump to spec, timed the BK mod to spec, and put the clip back to stock position. Took it up the road, "Bo-Waah", back to square one, just as bad as when I first started. Could my cam timing have something to do with this, cause I'm stumped! I'd like to really ring her out, but I'm not too confident on the big stuff right now. Please help!
