I have a HD SE turnout pipe. I guess we could try and check if it's running rich.

Since mine runs great with 1/2 a spacer but still pops every now and then, I'll remove the whole thing and see how it runs. Better off a little on the rich side than too lean. I can always undo it.

I think the consensus on this board is that removing the white spacer will give you an overly rich midrange. I think with a free flowing muffler (Supertrapp, Raask, Jardine, and Mac, Screaming Eagle) , 1/2 spacer is perfect. If stock or running a not so free flowing muffler (stock Harley), maybe removing 1/3 of the spacer (run one that is 2/3s the thickness of stock). Going up one size on your pilot jet will also alleviate some of the popping.

I completely agree! Grin

I have stock exhaust, intake, and jetting and removed my white spacer for lean running surge, especially at cooler temps, and it runs great now with no complaints. (Except my mpg has dropped from high 60's to mid-50s)

SavageDude, how'd you manage to paint your exhaust black without the paint peeling? I used some high-temp 1400F paint, and it still chipped off or bubbled!

Took the spacer out all together,(152.5 main,Mac exhaust, factory windscreen) This was on the flat, sitting upright, temperature 49 degrees. 6460rpm on ENM tach. Man this thing screames, pulls like a freighttrain till 90 indicated (on speedo) Popping is now rare and gone altogether between shifts. (used to pop all the time). Exhaust runs so clean, that when i put my fingers in, they stay clean. Never ran this strong and I think it'll pull past redline if I tucked in. The indicated speed on speedo was 98 (so slightly optomistic) Love it! With lower gearing (chain) I am sure it'll do or go past the Ton on the Sigma!
