SOURCE: kawasai z750, keeps blowing main fuse


To my knowledge, there are no onboard electrical/electronic components capable of shorting and blowing the fuse with out blowing any of the secondary fuse. The main fuse could possibly blow due to a short in the wiring or an exposed/frayed wire touching the body. The three most likely areas would be:

  • wire harness leading to the regulator;
  • wire harness leading to the fusebox; and/or
  • wire harness leading to the ignition switch.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

SOURCE: engine will not start,carbs cleaned, but will not fire, no petrol

Check the carb diaphrams for any tears/pinholes? (They are on the top of the carbs) Have you reconnected the breather from the tank? Is fuel getting past fuel tap? Sometimes the vent in the fuel cap can get blocked with crud and create a vacuum which stops fuel flowing.

SOURCE: i have a 2009 kawasaki 250s the bike only has 100

Apply full throttle and retry....if no go remove spark plug and see if there is spark. Clean / retry.
Check also for fuel supply.

SOURCE: my gs500f is back firing through the CARB. the

Lean mixtures burn very slowly, at times slowly enough to continue burning through the power and exhaust stroke, causing a backfire when the intake valve opens, and that flame gets a shot at the new mixture charge.

In normal operation, as the engine slows, the fuel delivery from the main circuit falls off, and the idle circuit is supposed to take over. If the idle circuit flows insufficiently, that becomes a transition to fuel starvation.

You can try pointing an unlit propane torch into the inlet air, and see if you can get closer to an idle while supplying a supplementary fuel source. You will need to do this in a way that gets propane to both carburetor inlets, maybe rigging a Y with vacuum hoses and electrical tape...

This started with work on the carburetors, so the fuel system would be the most suspect. That, and the fact that it will run at higher RPM would seem to rule out fuel delivery.

I was looking around at photos while developing this answer (needed to know whether this was a twin or a 4-cylinder), and one resource said the idle speed should be 1,200. I don't know if that's right, but maybe 1,000 RPM is too slow for this motor to keep it together. (I do doubt that, though.)

When I wrote that last sentence, I started to second guess myself, thinking "What if the fuel shutoff(s) is/are vacuum operated, and as the bike approaches idle there is insufficient vacuum to hold it/them open?" But the I rejected that, because there is even less vacuum at cranking speeds, yet the bike starts.

2009 Ninja 650R main 30amp fuse keeps blowing even with bike turned off (takes 3 minutes with bike off for it to blow). Been threw 3 new fuses and cant located the issue. Please advise me what to do?

Hi, Sheridan before diagnosing your blown fuse issue, check the bottom of your seat, if its metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom etc.) You are going to need a wiring diagram from your service manual, a test light, an ohmmeter and plenty of extra fuses.
If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with an ohm meter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any number reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

Went for a ride parked the bike for 2 days at my old mans ....heavy rain occurred...not winds over not firing?? please help

Hi, Dean and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

I am a new rider. Have no problem with clutchwork but when cruising and I speed up or slow down , the bike kind of jerks or lurches.

Hi Dave:
I see you're riding a 2009 twin. Very nice bike.
It sounds like you may be getting some unwanted throttle input or possibly mis-firing.
It's possible that a tune up may provide some improvement.
I'd be checking the plugs, air filter, clean the carb(s), and make sure the throttle cable and mechanism is functioning properly, from my wrist right on through to the carb.
Happy Riding!

77 kz 1000 police with 40k mi.was neglected for yrs. compression is close to 90 on all 4 cyl. have just rebuilt the carbs,put high tension leads on the coils after coils tested good at the...

It would help if you knew why it stopped years ago, wether there was a problem or it was just parked and running fine.
You have probably tried some of these but
Put the needles back in the original place, as this couldnt have changed while the bike was sitting.
make sure it has a good standard aircleaner in it.
change the oil
has the exhaust been changed
does it blow smoke
are the fuel lines correct
does the vacumn fuel tap work correctly(flows on P, stops on ON or RES) only run the bike on ,ON or RES.
Do the carbs flood
Fit new plugs
check all valve clearances
There are also some resisters in the plug caps that can fail(this would not affect all cylnders)
It the battery good and the correct one for the bike.
Is the charging circuit working 12v at idle and rises to about 14v when its reved.

I tried to start my '85 kawasaki 454ltd for the 1st time this

Sounds like a bad CDI box. That is part of the ignition. Do you use a fuel stabilizer when moth balling your bike each year? That may have been part of the backfire and shut off. Your bike having carbs may have gummed a little. Are you handy? Try spraying a small shot of starting fluid in the air cleaner,small shot! Just to make sure it's not a fuel problem. Try a different plug in the wire also. Sounds weird,because I'm pointing out fuel starve problem but the plugs could be fuel fouled. Anbd a new set of plugs for that bike shouldn't be that expensive and a good place to start.

07 kawasaki kx250f backfires

Hey i have several solutions for you.
The first is have you checked valvue clearence lately, because if the valvue clearence is either to high or to low then it could cause it to back fire. The next solution is repacking your silencer. The next solution is there is two main gaskets in most dirtbikes, one, which is located where the pipe mets the motor. Also the other gasket it where the mid pipe meets the head pipe. The bike fire is usually being caused by extra air. By the way checkin valvue clearence is extremley easy it may sound hard but I do after every ride.

Bike wont start

What do you mean "take out 1 plug"? Spark plug's plug?
Spark plugs are renewed?
You should also check the gears/sprockets that connects the starting motor with the crankshaft if all of them can spin freely around their pin.

KLX 250 won't fire - new battery

-check the fuse right hand side below the fuel tank and seat, see if it is blown.
- Check to see if plug has spark, replace if necessary .
- Did you run the bike with a low battery before replacing it? could be that your stator is shot.
-Is bike trying to start but won't?

Electrical problems

Ok good luck finding a wiring diagram to do this! Also this i a very bad idea if you manage to bypass the fuse box as your bike will then become a fire risk if you have some sort of short while riding your low amp wires will melt which will then melt the higher amp wires and add a bit of heat and oxygen and you have yourself one burning GPZ 1000
