Clock and Trip Meters resetting on start up

Hi all. I have an '07 RWB.  Just turned 2600 miles.  My bike occassionally will reset the clock and trip meters when I am starting the bike.  My '01 sometimes does this as well.  I thought that these Honda's were supposed to be the pinnacle of reliability...not really seen that so far!  Even my Triumph's didn't have the electrical issues that these VFRs have had.

Has anyone else had this problem?  I am thinking that I will make sure that my high beams are switched off when I am starting the bike and that might help.

The bike has the original battery and RR.  I have not had the battery tested but it seems to be working well.  It cranks the bike even on cold mornings!

The only reason this happens is voltage drops below a certain level which causes a rest.
Two basic reasons for this:
either bad cell or not fully charged battery
or starter or some other component drawing way too much voltage under start up making it dip below whatever that min level is.

Most likely battery related IMO.

Mine did the same thing the other morning.  I'm thinking its battery time.

Hopefully it is the battery.  I was planning on replacing it anyway.  The PO was not a battery tender disciple like I am!

I would also lay my dollar on the battery bet. Mine have always lasted between 6 and 7 years. An '07 battery is coming close to that window and only having 2600 miles, I would say that even if you were a battery tender man, the relatively low cycling of the battery might add to its demise.

Battery 1st, starter circuit 2nd...

I've had similar issues with mine, although it also was cranking a little slow.
Guess it's time to bite the bullet One time years ago I pulled into a gas station and filled my bike up.
When I went to leave the battery was stone dead. Couldn't even bump start it. No warning at all. :pissed:

I'm thinking one of those LFP batteries, even though they cost twice as much.
No need for a tender, lasts twice as long, or so they say.   :unclesam:

Hi DBii,
My logic would follow BR on this one.  A measured excessive current draw during cranking is possible but less likely.  A poor performing charging system could create this problem and other symptoms, too.  My 5th gen had occasional problems with the headlamp circuit not recovering after being bypassed during cranking.  Something like this might be a remote possibility, but unlikely.  Despite being charged adequately, a five year old battery may not be able to maintain minimum voltage specifications during cranking.  A professional comprehensive battery capacity test would be my first step.  Given the battery’s age, you may be purchasing one soon in any event.     
Good Luck,
Rick

I'm seeing the reset problem occasionally, too.  I notice it more often when a) the weather's hot and b) the engine is hot.  Cold mornings or cold starts don't seem to trigger it.

And I think my battery is just a year old.  :(

battery is being drained more than likely due to a failing reg/rec or stator.  I would suggest getting both looked at. I had this problem last summer and replaced the battery and a month later the bike died on me while out on a ride and I had to replace all 3

I have this happen every now and then when it is cold out. I find that it is less likely to happen when I let the bike sit for an extra 4 or 5 seconds after the system boots up. Could just be coincidence but it has worked so far.

This happened to me fairly recently. The clock and trip meter were getting reset but I kept riding until it didn't start back up after a stop at late in the night far from home.

Was afraid (still afraid) that it might be the R/R or stator or wire harness but so far, replacing the battery seems to have worked.
#13
Aren't these symptoms classic R/R?
#14
Lead acid batteries are remarkably reliable, while the same Cannot be said about the stators/RRs on VFRs. I had the same symptoms last summer, changed the battery and the problem 'went away'.  Until this summer went it resurfaced.  Turns out the stator was cooked, as in burned to a crisp on 2/3 of the poles.  Changed the stator, recharged the 1 year old battery and I'm off and running...

The difficulty in assessing the failing stator is that it is not a on/off type of failure, but rather progresses gradually, as more and more of the poles overheat and burn their insulating varnish on the wires.  The R/R failure tends to be more immediate.

That one sees the clock reset more in hot weather most likely is due to the added load of the cooling fan, pulling the battery voltage below the critical level.

HINT:  If you are stuck in the hills of West Virginia, 2 hours from anything remotely resembling a useful garage and your dash turns off, do yourself a favor and UN-PLUG YOUR HEADLIGHTS!  Worked for me.  I bump started the bike and ran the battery into oblivion until I got to Harrisonburg, to Blue Ridge Motosport (Honda Powersport dealer).  Luckily I didn't get caught in any traffic otherwise the fan load would have done me in....
