1981 kawasaki Z 250 C Questions & Answers
I'm helping my son-in-law fix
It's only a 250 so it'll feel light to the touch. On the handlebar lever there is a cable attached with a slotted knurled nut, this can be adjusted to add about 1/8th free place before some tension is felt. If not tension is felt and the lever just flops then the clutch is way out of adjustment tighten it up,
Normally this Knurled nut (it's actually a round grooved nut you twist or screw using your fingers) has a full adjustment range from the lever to completely unscrewed of about 1.25 inches
Adjust the "free play" to about an 1/8th as explained if this doesn't help then internal clutch work is needed and best left to those that work with motorcycle and not a novice.
1980 z250c bike turns over
Possibilities are; handlebar kill switch is grounding out, kick stand kill switch is broken or needs adjusting, a bad spark plug, power wire to ignition has come unplugged, bad ignition switch, ignition system needs service, coil or coil wire has gone bad. This list is in sequence of likelihood.
Is it true that the camshaft on this model runs
Yes , many Japanese engines run the cam in the head with out bearings or shims between the cam and the cylinder head. As long as there is oil and oil pressure the set up will last for years. Your only option if you damage the cam or the head due to lack of oil or oil pressure is to replace the affected parts as a set (head, cam, oil pump, and contact breaker cover/bearing). With the age of the machine the parts from a dealer may no longer be available and it would probably cost more to fix the cycle than it is worth. Rather than put $1000 into repairing a 30 year old machine, you would be better off buying a brand new machine for $4000 or a newer used machine for something in between. Used parts from a donor bike would be the least expensive way of keeping your cycle on the road if the sentimental value is stronger than your willingness to let it go.
Kawasaki Z 250 C, 1984, wich Ignition?
Paul, I have looked on-line and get no definitive answer. One site listed the timing as "OHC". That tends to tell me that the bike probably has points. Just do this, on the left side of the cylinder head at the top, there will be a rounded rectangular cover plate held in place by two screws. Remove the plate and the points will be right in front of you along with the condenser and spark advance. I am not certain on the old Kawasaki's if the points were on the left or right side. Pretty sure it was the left.
.
There is an off chance that the points could be inside the flywheel or on the right side of the engine on the end of the crankshaft. That would be the only other location possible. I have seen so many configurations I can't keep them straight. And considering 25 years have passed. . . . .By the way, I think you may have a 1983 model sold in 1984. Write down the VIN # off the steering stem and call a dealer. They should be able to tell you exactly what year etc.. Google " vintage motorcycle parts kawasaki " and you may be able to find points and other parts. Do you know how to set the ignition timing?
Please rate this solution. Thanks!
Where does the hose from
hi.
that should either be the fuel pipe, going to the fuel tap.
or possibly a vacuum pipe, probably still going to the fuel tap (there may be a fuel cut off system at the tap depending on the model)
hope this helps
Hey i got my z250c
It needs a good battery( new)
It can also damage the regulator, jump starting off a larger battery, or running with a stuffed battery.
When the new correct battery it fitted, get a volt meter, and put it across the battery terminals.
It should read 12v engine stopped and about 14v engine running, if it doesnt rise the regulator may be damaged.
The fact it is boiling the battery may just mean the regulator is working, but just cant charge a shorted battery
Re my query yesterday,
Hi, Castle Hill Motorcycles seems to be the main bike shop in your area, lot of dealers go overboard on repair work, grab your local phone book and even your local accessories store usually will know someone who repairs bikes in your area without charging and arm and a leg, shop around, what is the problem with the bike, maybe you can fix it yourself!!!
I have a 1981 kawasaki

Unless the carbs and tank were carefully drained when it was parked up, you're going to probably need the carbs and fuel system cleaned. Miracles can happen though, put a litre or so in the tank on reserve and give it a go. The reason I say a litre is that it's not a lot to drain when you find the bike doesn't run worth beans. Some people would pull the valve cover off and oil up the dried out cam and followers before starting but it's unlikely you'll cause any damage. If you do need the carbs cleaned, don't let just any idiot do it. Take it to a pro.
