Hi Guys, i've lurked this site for a little while and read through several dozen pages of posts and it seems like you guys know what you're talking about for the most part. I've had this bike for about 5 years, I do all the preventative / regular maintenance myself and have maintained the bike quite well in my opinion over the years. This spring, when i took it out of storage, I drained the gas, cleaned the plugs and started it up without too much of a problem, but I had a battery booster pack attached to the battery. After I went for a ride (about 20km of solid riding without any problems), i plugged in a charger and it read 8, i left it overnight and returned to the exact same thing. I tried to turn the switch on (which normally turns on the lights) and nothing happened, the starter wouldn't turn the engine over. The battery had a charge, but the only way I could even get the light on was if I had the booster pack attached to the battery. Can anyone help me out with some possible recommendations? Oh and the battery was purchased new about a year ago and was unplugged all winter and stored inside. It is an oem YUASA battery The bike is a 2000 DRZ400E with a few mods MCCT Twin Air Filter + Removed Snorkel / Rejetted Bored out stock muffler (previous owner...) Moose / Works Connection / Devol Armor Trail Tech Endurance Renthal Bars + Risers Pro Action Suspension and a few other goodies. Also looking into a new back tire. Currently running a 140/80/18 and ride paved cottage roads and mostly hard-packed trails, any input on something new? A few pictures. Thanks in advance for any help!
