Bansheexpx Posted September 15, 2008 Report Share Posted September 15, 2008 I know many people post without reading through the other post, but i have run a search and still cannot find my answer. My problem is fuel does not leak at idle..or even a little throttle, but after i ride hard for a few minutes you can see that fuel was slowly bubbling out the overflow at the bottom of the carb. Like I said, only under half to full throttle does it start to bubble out. If anyone has any ideas, they would be greatly appreciated.

LS1Inferno Posted September 15, 2008 Report Share Posted September 15, 2008 you have a verry little ring around the needle OR they are ever so slightly out of adjustment the float height on stock carbs is between 20 and 22mm i usually set min a 21 or they are just slightly dirty and need some cleaning.

Quadatic20 Posted September 15, 2008 Report Share Posted September 15, 2008 This is no big deal, drop the bowl then remove the float and you will see a needle there that will need to be wiped off. The needle needs to move freely so the float will work properly. Quote Link to comment Share on other sites More sharing options...
Bansheexpx Posted September 16, 2008 Author Report Share Posted September 16, 2008 I have already replace needle and seat. I searched earlier and felt that the needle and seat were my problem, so i know that is not it as i replaced those last week. Thanks for the ideas, ill check my floats again and im open to any other ideas people have. Quote Link to comment Share on other sites More sharing options...
#1JUANstunna Posted September 16, 2008 Report Share Posted September 16, 2008 Flip your carbs over and the line on the floats where they are put together, make it parallel to the surface of the carb, where the carbs and bowls meet. That's a real easy when to set it without a float gauge. Quote Link to comment Share on other sites More sharing options...
05.Banshee.SE Posted September 16, 2008 Report Share Posted September 16, 2008 I have a similar problem and am just going to clean and rebuild my carbs. Anyone have any links to good carb kits? Quote Link to comment Share on other sites More sharing options...
Bansheexpx Posted September 16, 2008 Author Report Share Posted September 16, 2008 I have a similar problem and am just going to clean and rebuild my carbs. Anyone have any links to good carb kits? Ill try messin with the floats cuz i just put in the whole rebuild kit. I think maybe one of my floats is not level. I will write back tomorrow on the outcome.

dajogejr Posted September 17, 2008 Report Share Posted September 17, 2008 If it's leaking out the bottom tube, remove the drain screw completely, clean that out with carb or brake cleaner, then tighten it back down. If it's leaking out of the two tubes on either side of the bike, then it's the floats. Those are the overflows...the single tube on the bottom serves as a drain tube. These are on stock carbs, I'm assuming. Quote Link to comment Share on other sites More sharing options...
jjn56 Posted September 23, 2008 Report Share Posted September 23, 2008 Bump, Did you ever get your leak figured out? I've got a similar prob and have done all the same trouble shooting also. Except mine leaks just sitting there cold. Quote Link to comment Share on other sites More sharing options...
Bansheexpx Posted September 29, 2008 Author Report Share Posted September 29, 2008 Bump, Did you ever get your leak figured out? I've got a similar prob and have done all the same trouble shooting also. Except mine leaks just sitting there cold. I have not yet figured it out. I have removed drain screws, and yes it is on stock carbs, and it is the outlet of the rear of the carb, the overflow/drain. I am still looking for ideas, however, the next idea i have heard and i need to check is the reeds. Apparently if a reed is cracked, it could potentially allow fuel back into the carb when i let off the throttle suddenly, so i will check that. Still open to more ideas.
