Hi, any help with this would be appreciated. I was running my ZX-6 D today burning off the old fuel in the tank and I noticed that the engine would surge up to 3-5000rpm. I figure this is a carb issue, could it be air in the system, need carb adjustment, or something else? I'm due to take it in to B.K. but I'm broke. I have the Clymer manual for it so and suggestions you have that I could mess around with would be great. I got the bike recently and have no service history so I'm assuming it could be almost anything. Thanks.
