Hi, I bought an 03 400ex about 4 months ago and I’ve used these forums to iron out a lot of the kinks. Recently I began to notice if I went to full throttle from idle it would bog down. I searched these forums a long time and now I assume it’s a jetting issue. I haven’t inspected the sparkplug yet and I know that should have been my first step but I stupidly skipped that. It has a fmf power bomb slip on and k&n filter, I replaced the timing chain with a crf450 chain and a few other things. Anyways I removed the main and pilot jets they were 140 and 38. I replaced with a 155 and 42. Now the bogging is a lot more noticeable and it happens no matter what rpm you’re at when you hit it hard instead of just from idle. What is my next step? Different jets, needle jet adjustment, air fuel screw? Also if it helps any, it runs fine with no choke but dies when I choke it, which didn’t happen before. Thanks in advance
