I just got a Iron Bay Regulator for my Saito 125, the manual just calls for you too richen the HSN 2 turns out than normal. Then you can go ahead and tune as normal. So I did my normal tuning procedures, I leaned HSN until I reached peak RPM then richened until I dropped about 800 RPM. Flying around at about half throttle I have a nice steady smoke stream from the exhaust but as soon as I open to full throttle the smoke disappears. Does this mean anything??
