Hey there guys.. new rider here.. Can anyone please help? My bike dies while idling in neutral, first... anytime when im not giving it some.. progressively i hear the revs lowering and lowering until it finally gives up. this happens every single time i leave the bike idling for more than 10 seconds! The bike is an oldie.. 1988 kawasaki zx2r 250cc, it has done 17500 kms. I dont know if this is related but also when i have the choke on the revs seem to fluctuate.. Any ideas!?
