Running rich.

Hi everyone. Just joined cos i just bought an 81 kz1000 ltd. Got bike cheep cos it starts but stops after a couple of minutes. Got me spanners out to see if i could get it running nice. First thing is plugs wet with fuel but when i took the air filter out the box was was swimming with go juice!! How the hell can that happen? Any ideas before i go any further. Thanks in advance for any help.

sounds like floats are getting stuck and not shutting off fuel flow to the carbs. That'll need to be fixed for sure. you should also check the oil for gas contamination if they're letting that much fuel out. could pool up in the cylinder and then drain into the oil. I don't know the specific float system on those bikes, but I'm sure someone will be along shortly with more details.

My best guess though is you'll need to take the carbs apart and clean them well, and maybe replace some floats.

I think you are way rich either due to sticking floats, needle seats not stoping fuel orfloat level is rediculousely high.Go completely through them by the numbers.

Thanks for the advice guys. Check it out this weekend and let you know what I find.

Checked the float hights & they were not to bad. So stripped the carbs. Couldn't see much wrong until i put the float valve under a magnifying lenses then I could see the ridge around the point. Gas must have been leeking past but only after I set off on a run. New ones in the post so hopefully this will cure it. Thanks for the quick response guys.
