I have a Honda activa 2011 model... When the bike simply standing at the time petrol leaking.. If it s half tank,full or end it s leaking not daily but some times.. Twice in a weak...how now a day s m stopping means... If it s leaking I ll go one round then it Ll not comes..

The initial questions I would have are can you see where the petrol is coming from, did it sit for a while before you got it, have you had any recent maintenance? Im not completely familiar with your model but I know that you have a carburetor. And im going to say that the gas is gravity fed, which means the gas tank is above the carb and it has a hose conecting the two. Start at the gas tank and check the hose for cracks, tears, and/or tight connection at the fittings. If thats all good ( from what you have said its more than likely ok )then move to the carburetor. You are going to want to take the carb off to do this so if you have a fuel shut off valve turn that off, if not grab a pair of vise grips and clamp the hose but take some old rubber or some thick cloth and wrap it around where you clamp because vice grips have a habit of putting holes and rips in the hose if clamped to tight. Be careful not to tip the carb over as there will still be gas in it. Either work in a metal pan or there will be a drain bolt on the bottom. The second one is better. Now if you flip it over after emptying the bowl you will find three to four screws. Take them out and open the bowl it might take a couple taps from the handle of your screwdriver to get it loose. It is a good idea to replace the gasket. Now there will be a float held on by a small pin. When you pull that pin out pull the float straight out carefully because the part you need is loosely connected to that. Make sure your working over a tray beacuse it might fall off. If it didnt slide it off and sit it to the side. Now hold the float up to a light and check to make sure there is no fluid in the float. If there is thats your problem. If not pick the piece up that was connected ( this is your float needle). There will be a point on one side. This point opens and shuts the gas port. There will typically be a wear ring around the piont. This ring is prohibiting the float needle from closing. This is more than likely your problem. Meticulously clean the inside of the carburetor because the only other reason for this to happen is that the float needle is being obstructed by dirt or old gas. Once everything is clean and the part that need replaced are replaced you should have no more problems. Its alot easier than it sounds. Good luck and I hope this helps.
