2000 450es- i rebuilt the top end .40 over - shaved the head - web cam - dyno jet kit - uni filter - ids II pipe. since then i've got a miss at idle after it warms up, no stumble or sputter just a dead miss every 30 seconds or so. it usually catches itself but sometimes dies, starts right back up though. PLEASE HELP!

Usually that means that the spark plug is old, or the slow jet needs just a fraction of a turn one way or the other. I wouldn't worry too much until you get at least a couple of miles with some good throttle (keep the RPMs down) to get the rings seated a little so the new engine loosens up enough to allow good idle.

Jake- I forgot to tell you the new engine has about 400mi on it. I'll try adjusting the jet, and see if that helps. Thanks for the help, I'll let you know if that fixes it.
