Top 20 1991 kawasaki ZZR 250 Questions & Answers

Don't jump the gun and replace the head gaskets like the guy recommended...you need to have a technician look at it...can be a minor issue or something totally different. I had the problem with my stratus and paid tons of money to do the heads...never solved the issue and heads were done right. Its was blockage with in the coolant system and was discovered til my water pump went out.

according to my handbook 350ml when empty 300ml at oil change. As a 2nd check i used a length of wire with masking tape then measure & mark the tape 135mm insert down into the fork. hope this helps it worked for me.

Need to make a compression test on each cylinder in case you need a new cylinder head gasket, test the thermostat and check that the radiator fan works ok.Also after installing a new battery (which you should cause the old one will damage you regulator eventually) check that the charging system works ok.

petrol is low swtch to reserve or clean your fuel **** they have filters on them may be block this happens from time to time and check you have a good spark

Starting from the left as you sit on the bike, is no1,

startermotor is failin or has bad connection--test it and chec wiring for titeness and corrosion

try cheapbikeparts.com

most likely a fuel overflow hose and it is simply a vent (does not connect to anyhtign)

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?

Hello. Get a can of starter fluid and a helper. Have the helper squirt some starter fluid into the air intake area while u start it. then use starter fluid to keep it running until it runs on its own. If this does not do it, you will probably have to rebuild the carburator. Joe

Hi, it should do around the 90-100 mph mark, hope this helps :)

Yep it could be the solenoid, best way to check is use a multimeter and check if there is voltage on the bottom terminal of the solenoid. if not thats the problem. But if there is voltage to it then you got worn brushes which will mean starter has to come out and get an overhaul...hope this helps. Let me know how you get on.

One or both of the floats are stuck open giving the carbs fuel constantly. The extra fuel runs into the intake, fills the cylinder, gets past the piston rings and then fills the gearbox and overflows onto the floor. Pull the carbs and clean them. Some trash, ( such as rust from the tank ), is not letting the float needle to seat. Be sure to sync and balance the carbs after re-installing. Also, turn off the gas at the tank when you are not riding. If you already are doing this, the petcock must not be shutting off properly and needs to be replaced. Please rate my answer. Thanks.

You will need to replace the kickstand switch

You must be proud for that,the cooling system is good,that means the engine life will last long

Hi and welcome to FixYa,

Initially, have the battery externally charged and load tested. This is to eliminate the off-chance of a battery issue.

Offhand, a couple of possibilities on the battery not charging:

• rectifier / regulator combo (most likely);
• loose, corroded, burned terminals / connectors from the stator to the rectifier/regulator (likely);
• faulty stator / coils (least likely).

On the speedometer not reading:

• faulty speedometer (most likely);
• faulty small gear on front wheel hub (likely).

Good luck and thank you for asking FixYa.

Hi and welcome to FixYa,

On a ZZR250, the only fuel line is from the petc0ck to the Tee between the carbs.

Good luck and thank you for asking FixYa.

Sometimes and usually a large nut with a lock washer and sometimes a large circlip , Wombat.

If it's ignition-timing it's designed not to be altered or set, why do you need to set it?

If it's cam-timing i'll put a detailed explanation, let me know m8.

Your bike is a four stroke. The gear box and engine are one unit. Standard 10w40 oil goes into the gearbox. The gear box oil IS the engine oil.
You need to buy the oil anyway, so why not go to the Kawasaki dealer and, after buying the oil, ask them show you how to check the oil level. Ask them to tell you what maintenance you should do as the owner. Don't be shy. Ask them "what do you mean by that".."where is that part on my bike?"... How often?... and so forth. They will be glad to give you a first hand education on standard maintenance needs.

Please rate this solution. Thanks!
