Did you upgrade plugs/wires? if so you need a tune up. if not then the electrical soilnoid box may be your problem.

carefully check plug leads and caps for cracks and shorting, there can be a small resister in the cap that can burn out, check by unscrewing the small brass clip that clips it to the spark plug inside the cap

Runs poorly, feels like miss fire, sometimes runs good(rarely).


You can do a continuity test on your coils and plug caps as follows:
1:Disconnect the coil connector drom the wiring harness.
2:select (O x 1)
3:put tester + lead on red/black terminal and - lead on orange(grey)terminal.
4:Your primary coil resistance should be between 1.87~2.53O at 20C.if OK proceed to step 5.
5:Select ( ωx 1k)and check secondary coil resistance(between the two HT(plug leads)this should be between 12~18 kωat 20 C/86 F).
You can also check sparkplug cap which should be 10k.ω
This is just a basic check but I would do is remove plug lead from the offending cylinder ,take up the revs and see if the miss-fire has gone.If so swap your coils around and see if missfire occurs on the other cylinders.If not your coils are OK.
If the missfire is still now only occuring on the one cylinder then you need to do a compression test()and if OK remove carbs and check also the inlet rubber manifold(for cracks ,seating etc.)and then service them.
Once off you can also see if the butterflies are in sinc.But do these simple tests and if you have a problem come back to me.

1991 fzr 600 no spark


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.
