Buzzing after a month sitting

Finally a nice day in Maine. But it only buzzed near my seat area when I tried to start it. I keep it on a tender and have taken it out a few warm days this winter.

I jumped it and rode for a half hour, but no change. Any suggestions before I lose it for a week at the dealer?

Thank you.

If you needed to jump it even though it was on a battery tender then I think you're in for a new battery

Dealer should be able to check charging system and replace battery in one day under warranty, they did it for me in 2 hours.
Yamaha requires full charging system diagnostic before replacing battery at their expense.

I rode mine in limping. Don't give them a choice. Tell them you rode there and it wont start. They cant just leave you stranded.

People will tell you to bump start or jump it. Battery will still die later. It clearly didn't work.
Other threads include premature battery failure and the like.

Sounds like a dead battery. I had one that would show full voltage until you cranked it for a few seconds, then it would drop to about 10 volts and just click. New battery fixed the problem.

Thanks everyone. Must have been a bad connection during the last charging. I hooked the tender back on it and she crancked back up after about an hour.
I'll keep an eye on it and have it checked if it persists. Thanks again.

Time to go to the dealer. It did it again. Put it back on the charger and got it to start. Ran it unplugged from the charger and it shut off after 15 minutes. Unrelated I think. It either automatically shuts off like some cars will, or it got too warm (the fan was running, but the temp was normal at 3 bars).

These bikes automatically shut off (I think the owners manual said after 20 minutes, but it could have been 15).

Have you checked the battery connections are tight ?

Thanks all. They put the battery on a charge, tested it while charging, said it was good. Then luckily it did it again as I jumped back on it. They ended up replacing the battery with one from a bike on the floor. They didn't recognize the one that was in my bike and thought it wasn't original.
I'm using or was using a Tender Jr. Anyone else using a junior?
