I ended up replacing the slow-jet from a #50 to a #45 and the main from a #148 to a #140 and I am running a 42-1 mixture. I am at 3000 feet above sea level and a temp outside of 90-100*. It looks better, but still a little rich. Think I am going to leave it cause my friend did a plug chop and open throttle (wot) and it came back lean, real lean! But my kids ride it and would never get that.
Also am running correct NGK plug now, and replaced the coil wire, and cleaned the air filter too.

Any ideas??
