luvkawzx6-R Posted February 24, 2009 Report Share Posted February 24, 2009 Hello all---I recently bought a 1995 kawasaki zx6-R. Bike ran great until last week. Seems like carbs are flooding out after a few minutes of running. If I turn fuel off it will run great until runs out of fuel in the carbs. I'm not sure if i have maybe a bad fuel pump or relay. Any help would be greatly appreciated!!! First nice day i'd like to be able to hit the road. Quote Link to comment Share on other sites More sharing options...
yotaman88210 Posted February 24, 2009 Report Share Posted February 24, 2009 First thing I would do is clean the carbs. YOu may have a little piece of gunk in there that is keeping the jet stuck open. For being almost 15 years old, cleaning will not hurt. Thats for damn sure. Quote Link to comment Share on other sites More sharing options...
luvkawzx6-R Posted February 24, 2009 Author Report Share Posted February 24, 2009 (edited) I was afraid someone would say that. I've never tried taking carbs apart before, kinda makes me nervous, may never run again. lol ... Although it seems to be dripping fuel out of carbs #1 and #2 Edited February 24, 2009 by luvkawzx6-R Quote Link to comment Share on other sites More sharing options...
yotaman88210 Posted February 24, 2009 Report Share Posted February 24, 2009 haha, yea I hate carbs too. If you take them off, you could ship them to someone or take them to a local dealer for a service. Wouldnt be as expensive since you are not taking the whole bike in Quote Link to comment Share on other sites More sharing options...
luvkawzx6-R Posted February 24, 2009 Author Report Share Posted February 24, 2009 That doesnt sound like a bad idea. I just hate paying someone else. Maybe ill attempt it. I guess a couple cans of carb cleaner wouldnt work Quote Link to comment Share on other sites More sharing options...
luvkawzx6-R Posted February 24, 2009 Author Report Share Posted February 24, 2009 Do you know any good shops i could take them to? I guess if i had them off it would give me a excuse for a jet kit Quote Link to comment Share on other sites More sharing options...
yotaman88210 Posted February 24, 2009 Report Share Posted February 24, 2009 you could try it. worth a shot to save you some cash. I mean a shop would prolly charge you an hour of labor... so youre looking at a little under a 100 bones Quote Link to comment Share on other sites More sharing options...
flounder Posted February 25, 2009 Report Share Posted February 25, 2009 (edited) If fuel is coming out, it sounds like it could be a stuck float.. pull em and clean em. By the way, if you have carbs, you dont have a fuel pump.. (re-read your first post) Edited February 25, 2009 by flounder Quote Link to comment Share on other sites More sharing options...

phugitive Posted February 25, 2009 Report Share Posted February 25, 2009 I think it is the o-rings on your 1 and 2 float valves. The float valve is a brass fitting, held in place by 1 screw, that your float needle seats against. It has an o-ring that seals it to the carb body and when this o-ring leaks gas keeps draining from your carb overflow. I have had these leak on several bikes thinking it was the float needle and turned out to be the o-ring. You should change all 4 while you are at it.

John Posted February 25, 2009 Report Share Posted February 25, 2009 if you were in columbus id come over there and give you a hand with them. carbs are not a mystical device. once you get into them they are actually pretty simple. it will run again if you go slowly. take your time and be patient. only take one apart at a time. that way you can refer to another one if you cant remember how something goes.the O-ring thing like phugivtive said is a possibility. another common problem is that you take the tank off, then when reconnecting the fuel line, you shear a piece of rubber off. ive had some bikes that the edge of the petcock was like a scalpel. that piece of rubber gets in your line and makes its way to the carb and jams the valve open. the fix is actually pretty simple. take the carbs off and drain them. open them up one by one, take out the float, and the valve and seat. dont bend anything. especially the little metal tang on the float that controls the needle. clean them, make sure they are not obstructed. take some carb cleaner and backflush the line. do it over a piece of paper and you can see what comes out. put everything back together, check the float level (although it should not have changed if you didnt bend anything)put a fuel filter in line and it should be good to go... you said it ran fine, so you shouldnt really have to fuck with the jets or anything. about putting in a jet kit... they arent a bolt on piece really... i mean they only screw in, but there are TONS of different sizes, and combinations. it requires tuning to get it to run perfectly at all RPM/throttle openings... you cant really just slap em in and have it be perfect.

flounder Posted February 25, 2009 Report Share Posted February 25, 2009 Correcting a technicality...Some carbed bikes do have fuel pumps.Really?, never saw one.. got any links to microfiche? How about a make and model.I just dont understand the concept to be honest. If it has a fuel pump, then it should be pumping gas into the injectors for atomization and not to a carb for atomization.

bigbluebird Posted February 25, 2009 Report Share Posted February 25, 2009 i had this happen on my 72 honda the floats ended up getting a tiny hole in them and filled with fuel and were no longer shutting the fuel off when the bowl was full. i ended up taking the bowl off the bike without taking the carbs off swapping the floats and then i was good as new. until in the process one of the 30 year old gaskets that i did not know was there turned to jelly and caused the bike to drop power at high rpm. so i had to find the gasket and get a new one. long story short get some new floats and a new gasket set. then start to fix them. took me a 2 hours to do the work and 2 weeks waiting for parts. total cost 30 bucks Quote Link to comment Share on other sites More sharing options...
luvkawzx6-R Posted February 25, 2009 Author Report Share Posted February 25, 2009 Thanks everyone.I pretty sure your all right, it definetly a carb issue. I do have a fuel pump though, it looks identical to the fiche dustinsn3485 posted. I thought maybe pump was still pumping even though carb bowls were full, but now that i look at it more closer only carbs 1 and 2 are flooding out. Time for a rebuild... Thanks again Quote Link to comment Share on other sites More sharing options...

EvilTwin Posted March 7, 2009 Report Share Posted March 7, 2009 I know your question has been answered but I just wanted to give you a heads up on a certain issue. I also have a 95 zx6r and in cold weather it doesn't like to start so I have to crank it numerous times; but because the fuel pump stays on it likes to flood. So if your ever having trouble starting your bike, remember to turn it off after every 3 tries or so. You may have known this already, but I'm just trying share some model specific knowledge.And I can back up dustinsn3485's claim 100% that 95 ZX6Rs have fuel pumps. As annoying as they may be they definitely are nice to have from a performance stand point. Although technically dustin, the ZX6R came out in 95, the 93-94s were just ZX6 (no R, model name ZX600E); though they look remarkably similar.
