Ok, I'm about 1100 feet above sea level. The bike is an '06 450F. I've tried everything with the stock pilot jet and cannot come to a compromise with it. Here's what I've done. I've turned it out to about 6 turns and the bike starts up great, sputters a bit with the throttle and deaccelleration. It won't idle. I can get it to idle when it's about 3 1/2 turns out, but it idles high. If I turn it out even another 1/4 or 1/2 it idles for about 5 seconds and shuts off. My main problem is this: when I have it idling with 3 1/2 turns out, it has a very poor response with 1/4th throttle (didn't get above that, testing in the back yard). I can barely pull the front end up. When I have it turned out about 6 turns, even though it won't idle, the response from 1/4th thru full is perfectly how I want it. So the question is should I go with a 45 pilot jet? Remember it's stock pilot jet, which is 42 (I believe). If I do need to rejet (I have purchased two pilots (45 and 48)), what's the easiest way to get to my carb? I took off my subframe today, because I tried the loosening of the carb clamps and turning in, so I could get to the float bowl, but it looks like what is the hot start cable is hitting the frame when I turn it. I can only turn it maybe 1/4th inch, which isn't anywhere enough to get to the carb. So, with the subframe off my intention was to get to the carb a bit easier by unattaching it and working on it while it's off the bike. Please somebody help me. Should I put the subframe back on and somehow get to the carb with it on?
