Well its spring again in Canada and today I decided to turn on my bike but no luck.

I have a 2000 Honda CBR600F4 with only 2700kms on it. Last season I purchased a new battery and changed all 4 spark plugs. Its been stored in the garage with fuel and without the battery for 4 months. At first it attempted to turn over but all I got was this loud bang coming from the muffler. However now it doesn't even attempt to turn over..all I get is this rapid clicking noise coming from the starter relay..? Any help would be greatly appreciated. Thank you!

 

the loud bang from the muffler was probably due to unburned fuel in the exhaust combusting. That happens when your plugs foul and gas just dumps in and out of the cylinders. A spark plug finally fires and ignites all of the unburned fuel.

The rapid clicking is more than likely due to the battery being dead, or a bad connection. These batteries do not last very long. A few attempts at starting and thats about all they have.

My guess is the battery was a bit weak, the bike didn't crank over fast enough and plugs fouled. then the battery went dead.

I would suggest recharging the battery and give it another try. However, with your plugs being fouled, you will more than likley have to replace them. You can try to pull them and dry them out and hope they are ok. But I've found its usually better to just replace them. Once they foul, they are weaker and foul much easier.

Also, if the temps are below 40degs F or so, it will be much harder to start and will take the exact correct start up procedure. If you did anything out of place at any point, it will usually result in fouled plugs.

 

Ok so you are suggesting to charge battery, check connections, check spark plugs?

Its confirmed the clicking noise is coming from the starter relay..? does this mean the battery is not powering it enough?

 

yeah thats usually from the starter/stator whatever it is that bikes have trying to start the engine but theyre not getting enough power from the battery to turn it over.

 

Ok I went ahead and recharged the battery and I also purchased 4 new spark plugs. After installing all the components I pushed the starter and the bike fired right up. I let it idle for a bit then finally took it for a 10min drive around the neighborhood. I brought it back into the garage turned it off for no more than 10mins took it out again but this time, as I was coming to a stop on a traffic light, the bike died out.

When I turn the bike on now everything works in terms of lights, horn, speedometer. However when I press the starter button a weak attempt to turnover is heard, after many attempts you will just hear a clicking noise coming from the starter relay.

 

my initial guess would be that either your rectifier isn't doing its job or your battery has a bad cell

 

Is there any way to test if the rectifier is working?

I would also suspect the battery. Take it in and have it load tested. Autozone, advance auto, even most small town autoparts stores will have the ability to test it.

that would be my first guess since its a new issue at the start of the season. Many batteries have failed during the winter/storage period, especially if not kept on a trickle charger.

But also check the rectifier as suggested. You can also check the voltage with the bike at idle, and at 5,000 rpms. You should be getting around 14 volts, maybe a little more at idle with 15 or so at 5,000 rpms with your high beam on. If your getting that, your stator and rectifier are probably ok. Check the battery voltage by itself and it should be in the high 12v up to 13v. If its low12's, like 12.2 or so, the battery is probably shot.

 

Well according to my mechanic the battery is juiced and perfectly fine. I cannot idle the bike..it will not turnover..any other methods of testing the rectifier ?
