Starting problem

[Ruby Racing]

Just a note, but when I changed my battery a few months back I found that the bike ran generally better as well.
I think just having a weak or tired battery can affect certain parts of the electrical system when running.
I'd like to be more specific, but all I know is I certainly noticed a difference.

You're right.  I've noticed that with my van. I don't use it much so the battery slowly discharges. So far it always starts, although struggles occasionally. But straight after giving it a full charge I notice the difference when driving. It is much more eager. I guess the spark plugs are getting a full charge and thus igniting all the fuel. Dunno, definitely runs better though.
