If I ride with my full jacket liner and heated gloves on, they will eventually kill even a new battery. If I shut them both off a few miles before I stop, the battery will fully recharge itself, so I don't see any issues with the charging system or battery.
I believe the system is adequate for it's intended purposes, but not sufficient for additional heavy power uses.
yeap, mine is 1994 w/ 35watt headlight. the charging system is WEAK! hopefully yamaha fixed that in the newer models. when weather is nice and no snow on the ground, i'm always on my bike. i work graveyard 7pm-7am; riding to work and home with dimming headlight when stopped, me no like. that is why i would love to upgrade all my lights to LEDs and a H4.
