I have a 1989 ninja zx-7r the problem i have is that when it starts and runs with the choke on only. If i take off the choke it dies, if i crack the throttle it dies, even when the bike is warm. Then after it warms up some while the choke is still on the rpm's jump up to about 4k and stay there. If I crack the throttle alittle it will bring the rpm's down to about idle. Does anyone have idea's sounds like I'm starving the bike for gas also I notices the the carb sliders don't move at all even at the higher rpm's could this be my problem ? any suggestions to help would be very appreciated.
