Ok so this problem has happened to me twice now, and I find it a little embarrassing. I need your advice. So last week I went to ride my bike to work. I started it up no problem, rode to a stop light and while waiting for this god awful light to change I turned my bike off. Right before the light turned green, I go to start my bike and it just couldn't turn over. It seemed as if the battery just wasn't producing enough power to start the bike. After rolling the bike into a parking lot and doing a running start to get to work ontime, it ran just fine. Later that night, when I left my job, the bike started right up. Now... tonight, I went riding with a couple friends and the same problem happened, except instead of at a traffic intersection, it was at a gas station. I'm thinking that maybe my bike's battery is starting to go. Could the temperature play a role? In FL, we're getting warm one week and really cold the next. I really need advice because I have a trackday coming up on Monday at Jennings and I want my 954 running tip top! Thanks! Also, since I mentioned it.. anyone else going to Jennings on Monday???

 

Similar thing happened to my 954; decided to replace the battery and no problem in over a year and 12,000 miles (I checked the charge system, too. Make sure the electrical system is putting out like it should).

 

Found the same thing when I had an alarm system on my bike and I stopped for gas. I removed the alarm system and no problem...

 

have the battery tested at a bike shop and check the charging system.

 

get it load tested. If it's holding a charge buy a battery tender n stick it on when your not using it.

 

Check the connections at the battery. My friends bike had a loose battery terminal...replaced the battery and the issues went away.The terminal was damaged in his crash, long story...

 

change the battery.....thats what i would do. the temperature shouldnt affect the bike starting. that and just make sure it warms up for a bit when its really cold

 

Why do you shut off your bike at long lights?

 

I don't shut my bike off at long lights, but I know in the summer the bike runs really hot at long lights. That's the only reason I could think of shutting your bike off at a light. But at the same time your fan isn't running so it is really not cooling your bike down at all either. Just leave the bike running. Once you get moving it should start to cool down.

 

Does sound like your battery. There isn't any reason other than your battery to cause this problem. You probably have a faulty cell that intermittently shorting out or something. Who knows? But yeah do double check your voltage going to your battery after you replace your battery. Make sure it is doing somewhere between 13.8-15.0 volts. any more then your reg is bad and your cooking your battery, any less than it isn't producing enough and it might be the reg or the stator or both? But one step at a time.
