So i am having trouble setting the carb correctly on my yamaha aerox. if someone could give me some pointers it would realy help. I have a 70cc stage 6 street race kit. 17.5mm carb with stock airbox with the cone. Have a derestriced exhaust and 4.5g rollers. i have a 55 jet in the bike yet the bike stick smokes like its running rich. im having a hard time beliving it needs to be leaner. when i go down the street it pops and backfires then dies and have to push back home. i dont really want to take off the cone from the airbox as it makes it much louder.
