Question about 1998 kawasaki ZX-6R Ninja

1 Answer

Firstly, my bike felt like it was running on three cylinders, reg-rec?

Firstly, my bike felt like it was running on three cylinders, I rode through this,, I decided it would be an idea to check and change the plugs, which in turn I did, nice and tight.. following this the bike broke down on my way home from work. The RAC guy came, the bike would start some times but under throttle would cut out immediately,, there was a clear clicking sound coming from the fuel pump,, which I have now changed,, yet the issue remains,, sometimes the bike starts and rides ok, but sometimes it has a different tone, will not rev over around 6k revs, just all feels wrong. A guy that worked on my bike a few weeks ago said my reg-rec might be shot and need replacing, there was evidence of some wires having melted in the bike.. do we think that the reg-rec might be an intermitant problem which has in turn caused my fuel pump issue etc etc.

Hi, Peter and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a "LOAD" test if necessary.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Fuel tank empty.
10. Fuel tank contaminated with ethanol sludge.
11. Water or dirt in the fuel system, or clogged filter.
12. Restricted, blocked or kinked fuel line.
13. Failed fuel pump.
14. Failed pressure regulator.
15. Faulty or clogged fuel injectors.

You changed the back pressure in the exhaust and that is what causing your problem either put the washer back in or have the carb properly jetted

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.

I think you could have an intermitant open circuit inside your battery. One of the links joining the cells is loose and makes contact sometimes and not other times. Replacing the battery could fix the problem. There appears to be notthing amiss in your charging system.

SOURCE: I have a Kawasaki Ninja,

There are adjustments on carbs for low speed air intake (air mixture screw)find out factory settings and reset that mixture.Sounds to me like those adjustments are out of sink.If so the bike will run very bad from idle to about 1/4 throttle then run great from there up to full throttle.this definitly sounds like carb problem.

Hi I have a Suzuki vl1500 lc is overcharging. cheack coil,regulator and rec but not the problem. its a brand new battery and bike is charging over 16.1 and up..please help thanks

Double check your battery to be sure that you bought the right kind. Also double check the reg/rec. This device is what is primarily responsible for the charging being correct. Overcharging should fall squarely on the shoulders of the reg/rec. if you didn't already replace it with a brand new part I'd still think that was the problem. If you did replace it, I suppose it is possible for your alternator to be broken and producing an absurd amount of energy, but I doubt it.

Hi all, looking for info circuit diagram / schematic about the insides of rec/reg box. I am in the UK working on mates 97 soft tail, keeps burning out reg/rec boxes 4 in 10 k miles. Is there a voltage...

This style bike,the voltage is also regulated through the black box on the front of the frame.Ive never heard of anyone doing this,but im sure its doable. Firstly,the regulator is mounted on the front of the bike supposedly to get max airflow,so a fan really isnt needed. I would first check the stator to see if its grounded,and see if the A/C voltage is correct. Unhook the stator plug at front of motor and crank the engine,with meter on AC volts,black lead to known good ground,and red lead to one of the stator posts where it comes out of the engine. With revs at 2000rpm,you should get between 26-30v A/C from both posts. If that checks out,set meter to ohms,with engine off,black lead to ground,and red lead to each of the stator plug posts. It should read INFINITE resistance,and anything below that,the stator has a grounded circuit. Another possibility is that they have bought the wrong regulator,as there are TWO different ones for different output stators.Also,is he using the style regulator that has a ground ******** it that is supposed to be fastened to the frame on one of the mounting bolts for the regulator? I hope this helps you. Let me know if i can help you any further.Good luck!

Hi. I have a 2009 xt660z, while out riding today the trouble management light came on, flashed at first then stayed on. I was in middle of nowhere with no phone, so tried to coax it home. After approx 1...

Hello there, I have a 2009 XT660Z as well and had the same problem, the chance are is the regulator/rectifier.

If you can jump start the bike with jump leads to get it going again, have a look at the head light while the leads are still on, is it bright? (should be as running fro another source)

Then take the leads off, look at the light and has it gone dim?

If so then it\'s one of two things, you battery is ruined or you are not getting power feeding back to the battery from the reg/rec.

For me this was corroded connections on the OEM connector sat on top of the reg/rec, I took that OEM junk off and replaced the wire ends with spade connectors, heat shrunk the lot (each spade and then the whole bunch to sit over the reg/rec too) and not a problem since.

Remember to take photos as you work, and keep them, that way you won\'t forget which wire goes where, as for the three white alternator wires mark them up before cutting off the OEM connector and take a photo.

Hope this helps, I\'m off to solve more problems with the bike now!

Bike has no power but will still crash start bike will also only go if the lights are on when lights are off bike have poor idel and will not accelerate i was thinking maybe ignition coil

It is more likely to be either the Regulatoer/Rectifier or the Magneto coils or pick-up. Your magneto sends a series of pulses at various revs. This is changed and evened out by the Reg/Rec. First step is to check quality of all connections from magneto upwards to all relevent components. IE; ignition coil, CDI unit, Reg/Rec, battery (if applic.). If the bike normally runs with a city light or running light when ignition is on, then check all switches for crossed, pinched or broken wire connections, especially around headstem area. Ideally, a service manual with relevent ohm resistance figures and a multi-meter should lead you to the problem. CDI units, Reg/Rec, Magneto Coils and pulse coils are very expensive as are ignition coils. They will all be affected eventually if the problem is not identified and fixed. Goodluck.

1987 Shadow 700 charging problem

yes there is a couple of different ways to test these components,first you will need a voltmeter and the first test is an ohms (resistance) test unplug the stator and place the meter leads on the stator leads 1and 2 then 1and 3 then 3 and 2 should read between .2 and 2.5 ohms then do an insulation breakdown one lead to stator lead the other to ground should read OL or OFL if any reading stator is junk. Then test out put meter to ac-volts meter leads to stator leads start the bike should read 15-100 vac. Then as far as the reg/rec goes set meter to diode mode and place one meter lead to the power output and the other to the stator input side of the connector do this to all three wires and then rev. the meter leads and do again 0.3-0.8 forward bias OFL in rev. bias then place meter lead to ground wire on reg/rec and do the same test if you get readings in both forward and reverse bias the reg/rec is bad replace

My hayabusa is still not charging the battery after the mechanic change the stator.

you may have a faulty reg/rec as well but get the wiring check to the reg/rec to.

I have a 94 cbr 1000 f i put a new battery in it, ran it around for 3 days, now it will only start if its hooked up to jumper cables and if the cables are taken off it stalls right away with no delay

you have a charging problem check the charging voltage should be around 13.50v if it lows you probley have a faulty reg rec or genrator test the coils of the genrator three yellow wires that plug in to the reg rec you should have restance of around 0.8 ohms when cold and no continutiny to earth test that you have battery voltage on the red wire and that you have continutiny to earth from the green wire if all that is fine you have faulty reg rec
