I changed a needle from stock on NECJ and leave standard the PJ nad MJ. On previous settings bike have more fuel consumption. Now the power is smooth, but if I looked on exhaust he's still too rich. I ran below 1000ft(250m) and around 32F(0'C). Settings should be ok, but looking there are too rich. Is something will change when I change a float level or I should go with lower PJ or main ?
I have one more symptom, when I drop throttle the rpms oscillate.
