do not just let it run
you are better off unhooking the battery and just letting it sit than cranking it and just letting it idle.
the charging system doesnt kick in until a few thousand rpms so idling will only drain the battery and letting the exhaust warm up and then cool back down quickly will cause condensation
oil changes are only required every 8K miles. most people change it earlier.

Ouch. Idling the engine will NOT drain the battery, it will charge it. I'm not recommending this as a means of maintaining the battery, but let's keep this factual.

I don't want to get into an argument, but idling the engine will most certainly NOT charge the battery. The engine has to be around 2500 RPM before the battery will get charged.

Yeah I have a battery tender for it and Im not just letting it idle I will be taking it out to ride im just making sure that no adjustments are comming up on it being that its so new. thanks for all the help

on page 17-7 of our service manual it says to test the charging system at 5000 rpms
on page 17-6 of same manual it says that a fully charged battery will read 13-13.2 volts

now considering that this same manual. the beat all end all of how to when it comes to this bike on storage

"for extended storage, remove the battery, give it a full charge, and store it in a cool dry place. for maximum service life, charge the stored battery every two weeks"

knightslugger was so kind to publish this charging system troubleshooting flow chart and you will note that you check initial voltage at 2500 rpms and should only read 13.5v
now consider back to what a charged battery should be 13.5

here is a thread with a good read.
got a quote from honda in it saying that the charging system doesnt kick in until 2500 rpms

I can only assume this reply is directed at me, as I'm the only one in the forum who's pointed out your misinformation. It boils down to this: Either I have a one-of-kind 2007 CBR 1000RR, or you're just another techno wannabe who gets his "information" from other unqualified wannabes. As we look into this issue, keep in mind that all I said was the battery is charged (not discharged) when the bike is idling.

Fantastic. How does this support your claim that the battery is discharged while idling? It doesn't, not by a long shot.

What's your point? Did I say anything to the contrary?

So because a generic troubleshooting flow chart says 2500 RPM should give you 13.5 volts, that means an '06 CBR 1000RR discharges the battery at idle? Wow, there's an air-tight case.

Yeah, more bogus information. You people are like a virus. The charging system doesn't kick in until 2500 RPM??? What load of crap!!!

I'm not questioning you, I'm correcting you.
You see, I'm not just some sportbike enthusiast with an attitude, I'm an electrical engineer. I've been charging sealed lead-acid batteries for 15 years using DC power supplies that I designed and built. I know a thing or two about this stuff. I also have extensive hands-on experience with the CBR1000 as I've done extensive testing with the fuel delivery, ignition, and charging systems. In developing my charging system failure detector, I made several measurements of the charging system performance, and I know exactly what a healthy charging system should do at idle RPM.
So what about you? Where does your technical expertise come from? How much have you personally worked with the electrical systems on this bike?
We can end this debate right here:
If you have a decent quality digital voltmeter, go out to your bike and measure the voltage at your battery's terminals, write down the voltage. Next turn the key to on, wait 5 seconds and write down the voltage. Start the bike (hi beam off) and measure the voltage after a minute or so, record the number. Turn on the high beam and record the number. Report back to the forum with your numbers and we'll discuss.

you are making it out to sound like just letting the bike sit and idle will cause the battery to go down.
quote:
no the cranking over and over and not actually bringing the rpms up will.
quote:
at idle the battery is not charging or discharging it is maintaining. since a battery will drain just sitting there on the shelf not to mention installed in a bike with the clock causing a constant draw. idle will not charge the battery enough to keep it full once it gets drained.

i saw a battery voltage major drop from key off to key on
idle voltage went to 14.4 on a warm bike at 1200rpms
so yes initially i thought i was wrong
with the high beam on idling the voltage dropped very slowly but still dropped
it went from 14.4 with the high beam off to 13.9 at idle with the high beam on after 30 mins of running undisturbed
quote:
so you can tell me all day long idle will charge the battery and i will admit that i didnt see a drop until the high beam was on but i will trust the evidence my own eyes showed to me over your word anyday. no offense but i dont know you or anything about your cracker jack engineering degree but i do know what i saw for myself

another one with that magic 2500 rpms number

there seems to be a lot people that believe the same way i do, maybe we are all a bunch of idiots but i have been called worse by people i can see face to face.

Is this a joke? We are waaaaaay past this hearsay garbage. 2000, 2500, 3000 RPM which is it? For crying out loud you just saw your battery maintain 14.4 volts at idle. That's the same voltage it gets when you're riding the bike, when the engine is at higher RPMs. Connect the dots man. Do you think your battery cares how fast it's moving when it's being recharged?
did you even ****ING read my post you piece of shit.
i watched my battery go from 14.4 volts to 13 volts at idle.
reread then go **** yourself
i am done i have proven my point to myself. you can sprout your BS somewhere else.
