I have had some problems, but I am still waiting for the needle to come in. Mine is snorkled, and sputtering was an issue along with the glowing pipes. As of right now mine is running good at 2 1/2 turns out on the fuel screws, and a little extra oil on the filter to richen things up a bit.
I plan to install #40 pilot jets(stock is #38), and rear needle in the front carb pretty soon. I hope this fixes my problem. It also seemed to run smoother with the DG5 turned on.
