Since last video I went from a #45 pilot to a #40. Haven't started it yet. Before that the spark plug was soaked with gas and black. So with the 45 it was way rich. Bottom end was girgly. Anything over 1/4 - half throttle in 1st and 2nd she took off like a rocket. I also moved the clip up one notch. The only other new plug I had laying around was a br9es. I just got my 8 in the mail. The needle was on the 3rd notch down. Now it's on the second with about 3 turns from seated on the air/fuel screw. It helped a tiny bit. I'm hoping with the #40 pilot it will be close to where I need to be. If not I got a 38, 42 laying around. It is definitely really rich though. I am running semi synthetic smokeless/ ashless amsoil. I Also just got a quart of mugal 800. Might not be the best for trails but I like to open my bikes up a lot. i think it sounds and runs much better just with the newer pipe I bought off a great member on this site. Can't you hear the difference? Pictures of my old expansion chamber. Looks like someone smashed it to clear the frame. I'm surprised it ran at all. Also the motion pro turbo throttle worked great. My original one was all taped up with electrical type. To bad, it was a nice piece.
