What kind of 'battery charger' ??
Is it a 'battery tender'...with a float-mode ??
May be it is getting tired...ready to retire.

How old is battery? It my be weak because of age also.

Odd mine did the same thing yesterday. SLow turn over and then revs slowly came up.
My battery is on a tender now as I ran it out last weekend and wonder if it never got fully charged.
Also I had only started the bike briefly to move it out of the garage and then a few hours later back in which is when it occurred.
I wonder if it did not like the 2 minute run period - it almost sounded fuel starved and then in about 30 seconds ran normally.

This is always a difficult one and we can go round the houses and then admit defeat and put a new battery in. While many get 6-8 years out of a battery, once a battery gets to 4 years of age and particularly if it has been abused ( allowed to go completely flat or overcharged) then you should not be surprised or upset to have to replace it.

But before getting your hard earned ready try this:

1. Check the charging circuit voltage - you do not want to put a new battery into a bike that is going to fry it and put you in the same position.

2. Remove the battery connections, clean them up and coat in petroleum jelly then snug them up firmly to ensure a good connection.

3. Measure the standing voltage.

4. Go for a ride of an least an hour.

5. Measure the standing voltage.

I did post in a thread somewhere of an inline voltage monitor that I fitted to my instrument panel if I can find it - you may wish to consider fitting it is very useful peace of mind considering the issues that arise with the OEM regulator.

After a night on the tender ( even with the trunk light left on ) the 650 started up eagerly and just purred all day.

Battery 4 year old. In past me bike battery last 6-7 year, perhap not so this one.

Will have battery verify next week, see if past test.

I'm not 100% convinced it was the battery but maybe the 1 minute run the night before left the bike stumbling a bit - it felt like it was not getting a smooth fuel flow for about 30 seconds and then was fine.

Today no issues on start but again tonight I did the 1 minute run to put it in the garage - will see tomorrow if it does the same thing as the battery is full charge now.
