Gremlins, please help

I'm looking for some diagnostic help. I was out riding today and noticed this combination of issues- odometer flashing on and off, loss of power (not complete loss, but definitely not normal power), and at one point the speedometer cut out and then came right back.

The bike never cut off and no warning lights came on (I don't think) or if they did tey definitely didn't stay on. Any thoughts? Anyone had the same issue? Thanks for any advice.

Did you lose your bell? Maybe loose connection on your speedo harness?

Grounds

My 08 did something similar but in the end it actually died after farting around for about 10 minutes. I pulled the seat off and the ground was loose on the battery. It has been a while since I pulled my tank off but it seems to me that there was a ground wire to the frame from the gauge cluster connector.

First thing that comes to mind, like others have said, is loose connections. Remove the small allen screw that holds the chrome (or black) bezel over the speedo. Remove, inspect, clean if necessary, and re-install the connector harness there.

Give the loss of power, I'd much more suspect the issue is under your seat though. Check that both battery connections are tight and clean. Often a screwdriver isn't enough, that's why those screws are also hex head! Put your wrench on it and get it tight, make sure they are clean and free of corrosion. Sometimes a little sandpaper on the terminals and connections helps, too.

Good luck!

Something similar happened to me last week on my 07 VN900B. My bike lost power at full throttle. If I ease off the throttle to say, half throttle, it will come back on, but if I go full throttle, it dies. It only occurred once and it went away after about 1 minute and hasn't happened since.

Back from when I was riding a two stroke bike with a carburetor, I remember having this issue if I keep the fuel really lean. With fuel injection and all, I don't know how it compares. I doubt it was a battery connection on mine though. Just wanted to share it in case someone has noticed anything similar.

When you say "loss of power" are you talking engine power as in it feels like it's missing a cylinder? If so then I would venture to say battery connection. If you are just refering to power to the instrument cluster and not the rest of the bike, then something with the ground or plug to the cluster. See Romans note above.

I have to agree with everyone else, you've got loose battery cables.

But not gut-busting tight!
