Question about 1991 kawasaki ZZR 250

1 Answer

Hi, my zzr 250 hadn't been started for about 8 months, so it fired up nicely with the choke on but once the bike warmed up I couldn't get it to idle once the choke was off, i tried more air to the carby but it will only idle at 3000-4000 revs. It fires up and slowly revs down and dies. It also rides fine but I come to a stop it revs down again and stalls. what do you think?

Could be one of two things
1. The carbs are gummed up. Modern fuel will break down after only a few months. The idle jets are quite small and will easily become blocked. Strip and clean the carbs.
2. The throttle cable is sticky. Less likely, but possible. Make sure it opens and snaps shut easily.
What do you mean when you say you tried more air?

Changed oil clogged air filter with new after market air filter bike ran good until the third time I started it it would not idle unless it was choked


My Harley is very slow to warm up, it also does not like to idle without choke unless it is good and warm. It could be the clogged filter was acting like a choke, but ruining your gas mileage. Now with air flowing smoothly the engine needs a bit of choke to idle. It should not need choke once it is fully warmed up unless your idle speed is set too low. With the engine hot, check RPM if you have a tach. If too low, adjust the idle speed at the carburetor. I suggest you find the adjustment while the engine is cold.

Idles with 1/2 choke. If open choke, or throttle - engine dies without any RPM spike. Carb was cleaned, jet is clean. When idles, there is gas in the primer bulb.


Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

5. Float level too low.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

9. Idle port, transfer ports, slow air jet clogged.

10. Slow fuel jet clogged.

Ltz 250 wont idle needs full choke to run.cleaned carb all jets new diaphrams. cleaned air filter and all hoses. backfires and hesitates half and full throttle.


hi,sounds to me like the air fuel ratio is all up the ***,locate the air/fuel screw on the carb(normally on the side)screw the screw right in untill it stops,then back the screw out 1.5 turns,this should get the bike to run without the choke,once you have the bike running simply turn the screw in or out untill the bike settles into a nice steady idle,should be good to go,hope this helps...cheers

Bike will not stay running with choke off.only has 600 miles on it.


It is likely that the dealer set the idle properly but as the bike is new it may need to be reset, most first services are scheduled for 600 miles or 1000km so that the dealer can make necessary adjustments.
You can check the location of the idle screw in your owners manual. Once the bike is nice and warm, try screwing the idle adjuster screw in 1/8th of a turn at a time until a steady idle is acheived. Otherwise take it back to the dealer, thats why you have a warranty.

It sounds like your bike has been sitting in storage for an extended period of time (a year or more) - and the carburetors are plugged up. If this is the case, they will need to be completely disassembled and cleaned out.
If it hasn't been sitting (and the carbs aren't plugged up) then check that all of the normal tune-up items have been performed, especially valve adjustment, oil and filters, spark plugs, etc. If this fails to produce positive results, perform a compression check on the engine. Each cylinder must be able to produce at least 140 psi of compression in order to run and idle properly.

!991 FZR 1000 Idle normal when cool, High when hot(2-3,000)


Sounds like you need the carbs cleaned and synchronized, then the idle set once the bike warms up. May also have a cracked intake boot, or a vacuum line off.
