Locate battery & recharge

Hi buddy what i would do is just bump the bike in 2-3 gear just simply go down a hill rolling then when you get enough speed let the clutch out and it should start then just leave it running for 10-20mins so the alternator charges the battery

The battery is under the seat. Take off the side panels, unscrew the seat and open the battery box. The battery can most likely be recharged but a trickle charger will not work...you will need a full-on battery charger and let the battery charge overnight. AutoZone, Lowe's and Home Depot all have rather inexpensive battery chargers.

WELL BATTERY IS USELY UNDER SEAT OR SIDE COVER SLOW CHARG IS BEST IF YOU HAVE CHARGER ALL YOU DO IS HOOK IT UP POS TO POS AND NEG TO NEG AND IF ITS SEVICEABLE YOU MAY MAKE SHERE IT TOP WITH LITTLE DISTILLED WATER BE FOR CHARGING BUT MAKE SHERE YOU DO NOT LET THING SPARK AROUND BATTERY CAN CATCH FIRE HOPE THIS HELPS

Rectifiers, coil pickups, stator plugs melting and the notorious cam chain tensioner are problems with this bike, i know i own an 87 and an 88. you can be lax with the three, but if you start to here chain slap, coming from the top end of the motor,.. change the tensioner quick! i changed mine out in 20 minutes and you should have seen its condition, it was wobbly, leaking, and worn on one side, the bike had approx 42k on it.

I had my battery die after sitting for a while on my CBR 600 F and I brought it to AutoZone and they placed it on a trickle charger. I see no reason why you couldn't do the same at home. And the others are right on accessing it. Simply remove the rear side plastics, then the 2 seat bolts (one on either side), and lift the rear of the seat up and pull back to expose the battery box. Jump-starting it is also a good method. If the battery keeps dying, I would check the rectifier/regulator. Mine went not too long ago as well and I found one on eBay for cheap $. Hope that helps!
