Guys,

I have a CBR 600 F2 (1992) model around 36000 miles.

It appears to have intermittent problem with the bike shutting off and then it would only start if it is jump started (jump leads connected to car battery).

So yesterday evening on way home from work, I was riding normal, I slowed down at one roundabout and the bike suddently stalled completely! I turned the ignition key, all lights came on and when I tried to start, it would just crank (try to start....tick...tick...tick).

I tried to push start, let it cool down etc.....but nothing.....the lights always come on, it cranks but the bike would not start.

So I called my bro to come with jump leads. When I jump started.....it fired up straight away! Working fine since yesterday! The said issue has now happened 3 or 4 times.....where the bike has stalled all of sudden and has started with jump start.

Just to let you, I have recently put in a brand new battery. And this was the first time since battery change.

Please advise what could be causing the problem and what should I check in steps or change.......I have not changed the spark plugs since I have bought the bike 6 months ago.

Thanks!

 

Check you charging voltage and for a burned r/r connection. Very common failure point on those bikes....

 

Thanks man. I will check tonight when I get home and post the outcome.

 

It sounds like you may have several things at play, but regarding the above quoted portions of your first post, if the bike just suddenly shuts down, but you still have electrical power, the ability to crank the engine, but cannot get the engine to fire, then that could be your kill switch needing the contacts cleaned/resoldered...it's a semi common occurence, since the electrical contacts in that switch are subjected to moisture.

When that happens, try toggling the kill switch off and on several times, and keep trying occasionally to start it - if it does suddenly start for you, then it is likely issues with the kill switch.
