RRFlea

Ive had my R1 Raven '06 for about 3 years+, last couple months havent been riding much nor turning on. Ever since it seems like my battery has been either going bad or loosing charge. I have fully charged my battery. What suggestions may anyone have after charging to find out if my battery needs replacement, will more constant riding after doing so help or what? Thanks to anyone willing to help looking forward to getting this issue resolved for I miss riding my bike, but before replacing my battery want to make sure due to the fact that my money is tight!
