Really...strange what you need to do is see if the bike is running too fat. So...warm her up witha fresh set of NGK! spark plugs. After the bike is warm take it down the street and back. When your on the way back get on the throttle and accelerate then shut er down and coast it into the garage. This will give an acuurate read on the spark plugs at operating temperature and under a load. Pull all the plugs. If they are brown like coffee with cream that means carbs are adjusted correctly. If they are black and wet too rich and if they are white or very light brown too lean. Other problems may be oil soaked plugs from loose top end parts. Maybe valves or guides.

you dont need your clutch to start the bike in neutral, the only wire goin near your clutch should be for your horn. the clutch is cable activated on the fzr, if you have no spark check your basics, fuse's relays and such. on the fzr there is two sets of fuses the four under your seat and then relays and one single fuse under the back plastic (left hand side if sitting on the bike). then the next easiest would be to check your wire's they need tune up's just like cars. other than that you are basically left with the digital ignitor or your coils, if you have power goin to your coils what about after them ??? Also the kickstand safety is only when the bike is put into gear it will shut off the bike if stand is down.

Sounds like your regulator/rectifier is faulty....but it could also indicate an alternator problem. Don't run the bike or it will eventually hurt your battery and/or your alternator (if it hasn't already.)

The wire currents, voltages, etc needs to be checked (from the alternator AND from the rectifier) so I recommend you take the bike to a mechanic unless you have a multimeter and shop manual handy.

I've found Yamaha wiring connections to be slightly weak....and sometimes lead to the premature death of the reg.rectifier. Solution was to 'solder' the connections instead.

Good luck with the FZR.

Check your battery cables to see if you have direct short. that is what it sounds like.
