Carb leaking after rejet doubt it's fuel line

[dadudeinbiloxi]

Here's the problem. I'm assuming it has something to do with the floatbowls because it did not do this after I rejetted it. As you can see from my videos etc i've posted my bike runs fine. I do not think it is the fuel line leaking.. I actually i've checked the several times and if I turn the petcock off it doesn't leak.. So it's the carbs or fuel lines. The fuel lines aren't even wet and as you can see from the quick picture I took of the left carb.

 

It does not leak bad this picture you can see it has dropped ontop of the clutch assembly. The green ooze.=P I'm sure it's an easy fix my bike runs fine except for when I turn the fuel/petcock off and let it sit overnight getting it started again is a reaal pain. I need to fix this leak anyone can pinpoint the problem right off the bat?

 

I'm running all stock, stock carbs, rejetted 320mains/27.5 pilots. fmf gnarlys and k&n clamp-ons. the rest is stock.

 

Also in the picture where i put the leaf if i let it sit with the fuel not on off it will leak and fill up in the bottom end you wouldn't even be able to see the leaf. Keep in mind it has to sit for a good while to leak that much it's very minute.

 

ps I havent had time to pull the varb and recheck the floatbowl I'm pretty sure it's the floatbowl but would what cause it to leak so much overtime? Sorry if this is garbled I don't have much time typing this, must leave.

 

Also wanted to ass I wiped the left carb down etc etc and all around the float bowl I could feel gas etc.. and the tube had leaked a good few drops onto the stator cover case another reason I know it's coming from the carbs.

 

 

 

Thanks in advance to all!

Um...so did you have the bowls off or not?

 

If not, then you have a stuck float. Usually you can fix this by taping the side of the bowl with the handle of a screwdriver. Worst case is you might have to pull the bowl off and it'll free up.

 

If you had em off, you could still have a stuck float, but add in the possibility of these: Bent float - there's a little metal tab that the float needle attaches to. If this gets bent it changes the level of the floats so the needle won't close off when the bowl is full. Second, you could've dropped the needle completely when you openned her up.

I agree on both points, because I've done it or had it happen. I had fuel POURING out of the bores one day. Bent tabs on both carbs.

no i havent even took them off since i've rejetted them it's been leaking a minute amounts like this for a month. I just now will have time to look into it wanted to see what others thought.

 

 

ps. I did tap the bowls with a butt of the screwdriver still no dice. I tried that two weeks ago. I will probably pull it tonight and try it, still leaks i'll get internally better pics of the carbs, thanks guys.

 

*walks out the door* bbl take it easy all.

Also one more question before I leave that annoys me.

 

When I turn the petcock/fuel to off let it sit overnight just one night.. the next day I turn the fuel on and it takes tons of kicks and like I said is a real pain to get going other than that it runs like a champ.

 

Is this normal when turning off the fuel or is it most likely related to my leaking problem? thus needed to kick it alot to cycle the fuel? I don't know.. that is why I ask. thanks.

[Wallrat]

No that's not normal. Sounds like you need to adjust your float height. Hopefully you've got a clymers on ya or somebody can chime in with the specs. Basically that little tab we were talking about, well you gotta bend it a c-hair at a time to make the float height change. Hehe...its pretty much trial and error - bend a little, reinstall floats and measure, bend it back cuz u went to far, etc etc...

 

Oh ya and if that's not enough, you might need to rejet since lowering the level in the bowl is gonna make you run leaner.

Can you tell exactically where the fuel is leaking from when you let it sit with the petcock on the on position?

Do you have the (2) drain hoses on, that hook to the bottom of the carb bowls?

Are the carb drain screws closed? Could be ur floats are stuck and need adjusted.

 

Did you have both bowls off when you re-jetted the carbs? If so you may have mis-matched them. I believe each carb has its specific bowl do to the choke mechanism so swappin' them will mess up your choke. That may have something to do with why it's so hard to start. Is the choke tube still connected between the carbs? May also be lean pilots. Where are your air screws, how many turns in are they?

thanks all, hey hil check, check and check , sync hose is there, checked that when i rejetted them. All hoses are connected and I re-jetted one carb at a time to make sure and not mix up the bottoms.

 

I do believe the leaking is coming from the left carb/choke one. I will pull it today maybe if I can get around to it. I think I have narrowed it down.

 

it leaks so little overtime to build up that I have not yet pinpointed it. It did not leak like this until I rejetted it so i'm sure it's something simple with the floatbowls/carbs.

 

Hopefully it is a simple stuck float.. I will see soon

 

thanks all!
