Hi all, im riding a 1985 gixxer and of late, when ever i ask for a quick response from the throttle, she just splutters. she can pull high revs but she has to be worked in, carbie and bike were serviced 2000 kays ago. Any-one else had this problem that can give a clue where to spend money on first before i replace engine to find out it was a lead (joke). she was running real sweet and could handle any quick snap of the wrist but some issue now creeping in. Thankyou for anyone who adds input, im extremely fresh to bikes - before last december never even thought about riding them. Im enjoying them now but mechanically clueless.
