I just finished setting my valve clearances and now it seems like it is running too rich. I adjusted the idle to 1200 rpm but when I rev it the rpms stay at 3k and then work down to 2k after a few seconds and after a bit it finally goes down to 1200 or so. On top of that when I get on it while riding it lags and get a little jerky from 4500 to 6k but picks up again through the rest of the range. I feel like it has more power than before but I can smell fuel when I stop. All I did was adjust the valves and now it's putting in more fuel than before. What should I do?
