so while running, noticed that the bike is kinda sluggish (still running the 20:1 mix) and inspected the NT speed carb for the needle setting and found it to be on the factory setting, 2nd to bottom and tried to raise the needle to the middle and the bike ran awful! 3/4 throttle and the motor would die. tried raising the needle one more notch (2nd to top) and the bike keeps on bogging down. anybody heard of too much air?
do i need to somewhat compensate the gas for the too much air being sucked by the engine? btw, sealed and checked all the possible airleak spots but found none.. any help would be much appreciated!
