My motorcycle (1995 Kawasaki Gpz1100) is not idling and accelerating smoothly. It requires alot of choke at startup. It used to startup with almost no choke. Once the bike has been driven for a few minutes I can shut the choke off completely and it will normally idle without shutting off. At idle it seems to fluctuate a little – sort of stumbling along between 800 and 1000rpm – even after. I think it should idle steady at around 900rpm. When I put it in 1st gear and slowly apply the throttle while letting out the clutch – the throttle is not very responsive. It’s not reacting smoothly to small throttle inputs. I’ll slowly apply throttle and nothing seems to happen, and then suddenly the throttle comes on. When I’m starting out from a stop I have to give it a little more gas to keep it from stalling. The throttle response is not smooth and linear.



The bike does not get ridden much – maybe 2k miles per year. It currently has 12k miles on the odometer. It sits in my garage most of the time. I also *think* that after I had the valves adjusted (last summer I think) that it required more choke at startup. The throttle response issue started and seems to be getting worse since the valve adjustment.



Thanks

 

Im not totally sure,, but if its sits for a period of time then the gas will go bad...

 

Check your fuel filter and air filter. Empty the tank and put new gas in, and check the plugs.

 

It's definitely bad gas. And adding fresh gas on top DOESN"T WORK. (as we all know)

If you plan on not putting any real miles on it, come up with a storage plan. (drain the tank & floats, fog the cylinders, etc...)
Also, check into sealing the inside of the tank. It's easy for you to do, and can be bought at any bike shop.
That'll prevent rusting, from sitting empty all the time.
Taking the time to store it, will prevent wasting time getting it to run when you want it to...

 

+1 bad gass or clogged pilot jets. the mains are used for going and the poilots are used for idling.

depends on how long you are going to let it sit. if it is just going to be a couple of months over the winter. stable works 100 times better. and you can still ride the bike without much preperation before or after the ride
