so i got this bike (99 zx-6r) and i've had it running many times i was pulling the swingarm spool off today with the engine running, and noticed a hole in the can, figured it'd need to be blocked for RWC so shut the engine off, plugged it with exhaust gasket putty, then tried to restart and it wouldn't. after a while of on/off starting it backfired, but wouldn't actually start. and yes i wiped away the putty, thinking maybe the hole WAS supposed to be there. tried bump starting too, exhausting and fruitless effort while pulling the spark leads off to check spark i *think* i may have torn a plug lead. well, it's torn. the cap and cable are separated. but from what i can gather that's how they're designed, so i might not have stuffed anything. the other 3 leads are fine. it's getting fuel, it's getting spark. but it's not getting running. have i missed soemthing??
