I have a 93 zx-7 and at the end of last season I started to have a problem with starting. I would have to jump start the bike and after an hour ride i could not get it started. Each time i wanted to ride i would hae to either jump start it or pop start it. I replaced the battery and still have the same problem. so I'm having the same problem this year. I broke out the DMM and tested the battery and it ready 12.6 volts but when i turn on the key it drops down to about 8 volts. Any help with this problem would be appreciated thank you.
