i used to get oem yuasa batteries for these from motorcycle batteries usa for $85 but it looks like they're out of business now. Like everyone said check all your connections. Also if you are doing alot of city riding the battery will get weak as its not really charging till your 5+k rpms. Run around stop and go traffic or turn the bike off and on a couple times and the battery tends to get weak. You'll need to get out and ride it higher rpm wise or get you a trickle charger setup in your garage/parking area. The oem battery really doesnt take alot before its too weak to handle starting the bike.

 

Thats great, im actually from fairfield but we can meet up in clifton somewhere, cuz thats where my buddies are from.

 

yes, i know what your talking about... it does that no matter how high the rpms are ... for example a 2 hour ride to PA... with the least rpm's around 9k practicaly the whole way down...same thing again.
