Dxr Posted July 10, 2011 Share Posted July 10, 2011 Noticed a puddle under my bike after a good days riding, checked it out and its petrol. I removed the tank bolt and LH side panel and noticed the fuel dripping from the air box so I removed the air box cover and it was full of petrol, filter drenched in it. I turned the tap off and emptied the air box which seems to have stopped the flow. Quick google search tells me various poss problems but my knowledge of carbs/floats, seat valves etc is nil Any advice, no matter how obvious most welcome. Anything else need rectifying as a result of this overflow? Quote Link to comment Share on other sites More sharing options...
N1NJA Posted July 10, 2011 Share Posted July 10, 2011 I've just stripped off and cleaned my carbs on a zx6. There all the same, basically your carb has a float system that regulates a certain amount of fuel stored in the carbs all the time. There's a valve on the back of the float which i'm guessing ones stuck in on your bike. Do a quick YouTube search for carburetor strip and clean you'll see.

Colin the Bear Posted July 10, 2011 Share Posted July 10, 2011 Works like the ballcock in the loo. Not saying your bike is a toilet by the way Quote Link to comment Share on other sites More sharing options...
Dxr Posted July 10, 2011 Author Share Posted July 10, 2011 Thanks for the replies, I shall research carbs more in depth tonight... watch out youtube. lolWell I think whatever it was is now cleared and ok, I'll check later to see if its leaking again. I disconnected the tank. Cleared the airbox of fuel and checked as much of the carbs as I could from the top, all looked clean and clear. I knocked gently around the floats so hopefully thats worked but in the end put it back together and after a few attempts it started. Ran it until warm and it seemed fine even at higher revs, air filter is still saturated though from the orig overflow Good to see more of the engine up close though, all part of my intended learning curve. Would have been nice not to loose a crap load of petrol though If it leaks again tonight I'll need to figure out how to stem the flow until I can strip more of it tomorrow Quote Link to comment Share on other sites More sharing options...
Dave33 Posted July 10, 2011 Share Posted July 10, 2011 Hey Callum.Hope you got this all sorted in the end bud My old MotoX bike did that once and it was the carbs Quote Link to comment Share on other sites More sharing options...

Colin the Bear Posted July 10, 2011 Share Posted July 10, 2011 Just a thought. Does your fuel tap have a prime position? Some joker tried turning my fuel off outside the pub but it didn't have an off position, just on , reserve and prime. Ran half a tank onto the floor. Just a thought.

Dxr Posted July 10, 2011 Author Share Posted July 10, 2011 Yeah its the same, ON-PRI-RES but its got one of those auto fuel off vacuum valve things. At first I thought it was that that had gone iffy. SO far it does seem to have been a mucky float or similar... I hope Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted July 11, 2011 Share Posted July 11, 2011 the vacuum doesnt work if you have the fuel tap in the prime position that allows free flow of petrol, you should only ever have tap in the prime positionif you have drained the carbs or run out of petrol and then as soon as the bike starts move tap back to the on or reserve position Quote Link to comment Share on other sites More sharing options...
Fozzie Posted July 11, 2011 Share Posted July 11, 2011 Take the carbs off, remove the bowls and hey presto there is your floats.If they are the problem you will notice they are filled with petrol and that indicates they are nackered and need replacing. Or the float piston, which blocks off the valve letting petrol get out is gummed up and no working. Check these if its a persisting problem with the fuel set in anything but off Quote Link to comment Share on other sites More sharing options...

Colin the Bear Posted July 11, 2011 Share Posted July 11, 2011 Add some RedX for a few tanks. Then every now and then to keep things clean. Quote Link to comment Share on other sites More sharing options...
Dxr Posted July 11, 2011 Author Share Posted July 11, 2011 Thanks Colin, I put some in when I got the bike. I'll keep on top of it Quote Link to comment Share on other sites More sharing options...
Fozzie Posted July 11, 2011 Share Posted July 11, 2011 I use STP rather than redX. The local Honda mechanics say its better. Not to put Colin down I was of the same persuasion until I got a good talking to over it Quote Link to comment Share on other sites More sharing options...
Roadtorque Posted July 11, 2011 Share Posted July 11, 2011 Most bikes with a petrol tap, think you will find the hand book recommends turning it off when not in use,,,,,,, Quote Link to comment Share on other sites More sharing options...
Dxr Posted July 11, 2011 Author Share Posted July 11, 2011 For those with taps that have an OFF, yes mine has no OFF Quote Link to comment Share on other sites More sharing options...

Reserve is a switch on the bars. Very convenient Quote Link to comment Share on other sites More sharing options...
