Recently checked and adjusted my valves (left intake was 2,000s out of spec) and swapped out my 42 pilot jet for a 46 to combat excessive backfiring I was having. Mixture screw is set at 1 1/4 turns out and overall the bike runs awesome but man is it a b***h to start. Talking about 5 - 7 kicks before its running then after letting it warm up for a couple minutes with the choke on, it dies when I go to take it off the stand. After it dies it is nearly impossible to start and requires bump starting. I'm new to 4 strokes and am not quite used to how finicky they can be as compared to their 2T siblings. Is there another jet in the carb I should change since I adjusted the pilot? Any thoughts are appreciated. Thanks.
