Hello,

i just have my cbr600f2 1991 for 2 months and I’m loving it.
Yesterday I noticed that my headlight was broken but I had to be somewhere so I took the bike for a ride.
then I noticed that the indicator lights where always on(not off or on/off) but when signaling it was making the light brighter. And I started to smell this thing and it was not nice. Like a sulfur of something stinky...

apparently the battery was leaking which gave the nasty smell and I have only replaced The headlight and removed(not replaced) the battery.

now when I run the bike on the headlight works and the engine is running. But the indicators are still constantly on.

So my question for you guys: should I be worried about something or what could be the problem?

 

All the signs of overcharging. Have you checked your voltages? Id it is indeed overcharging, it can really mess things up.

 

My first guess is that the reg/rec has gone the way of the dodo.
So like 74demon said, check the voltage and report back.
