Bike just shuts off

Went riding today, was a nice 50 degree day so i thought i would put put around town and get some miles in.

After about 1 hour of riding I was downshifting as I came to a light. Bike just shut off as I pulled the clutch in from 2nd to 1st. I didn't pop it back out cause I didn't even realize the engine shut down. At the light I restarted the bike after a try or two. Turning over sounded weak.

Bike started and I thought wierd but kept riding. 1/2 hour later same thing. Downshifting from like 3rd to 2nd and engine off. Again took me by surprise so i didn't pop the clutch. footed it off to the side of the road but this time bike turns over weak once or twice and then dead battery.

Had a tow truck come out and give me a jump. Bike started right up. Rode it home.

Dead battery? Or something else? Its sunday but I think I know who has a battery for RC's. Gonna replace it no matter what. But ya guys think something else is going on? What ever happened to a bad battery the engine would still power a car or bike until you stopped. Is it now a dead battery = engine off?

Hope its nothing more serious then that.

Re: Bike just shuts off

Most likely the battery needs replacing. If it happens again with a new one check the R/R.

More than likely the Batt. When you get it started again, disconnect Neg battery wire while bike is running and check voltage output across Pos/Neg battery wires to verify correct voltage to Batt.

Re: Bike just shuts off

Everywhere is closed today after looking so I have to wait till monday or tuesday for a battery. I do have a power commander in and when I took the bike for inspection the guys said the idle was too high at 1800 and dropped it to like 1100 (the only change I can remember).

I guess after the battery is in place I can see what the voltage is doing from the charging system.

What numbers should be coming back across the wires to be healthy?

I believe it's 12 to 14 VDC.

If the charging system is not putting out enough voltage the ignition and fuel delivery systems will not work. If the batt is in bad enough shape (bad cell or shorted) it will not allow current to pass through correctly even if the charging system is functioning. If it is your original batt it is time for another.
I found the best deal at Batteries Plus, if you have them in your area.
After you install the new batt, check the voltage across the terminals. Start the bike and check again. The voltage should be more with it running, generally high 13 volt range. Rev engine slowly while watching the volts. It should go up slightly. If it goes down you need to have the charging system checked out by a tech.

Conquer yourself rather than the world.

Re: Bike just shuts off

Crap, went out today for a ride, new battery and bike shut down three times.
Once slowing up to a light, clutch was pulled in going from 2nd to 1st.

Once while at a light clutch pulled in and in 1st waiting for a light to change.

Once in a parking lot. Pulled to a stop, kickstand down and in nuetral. was just sitting there for a sec and bike just shut right off.

Only good thing was since the battery was good the bike turned over each time and started right up.

But know I don't know what the hell is wrong. I'm pulling for either the bike idling too low (gonna up the idle tonight) or at the worst a bad kickstand switch.

Past that i guess I'm calling the honda dealer and seeing when I can drop it off to them.

Is it possible for a power comander to trip off a bike? I could try disconnecting that also to see if there is any change.

Re: Bike just shuts off

check the voltage regulator. If the battery is charged the bike will run off of the batteries charge till it is too low power anything. if the voltage regulater is bad than the battery can't recharge = dead bike. I had the same thing just happen to my f3. New voltage rugulator and i am back on the road. Follow this link to get a charging system trouble shooting chart. it was really helpful to me.

Re: Bike just shuts off

Looks like the voltage regulator is in the tail on my RC, I can see it from the trunk. Its also hot as hell to the touch.
