Carb Float Question!

Hi All, i'm new to the forum... I have been working on someones nsr125 and its been flooding its self. so on doing a carb clean and to see what the problem is i have noticed that one of the floats out the pair has some sort of liquid in it and the other hasn't, its about half full within the float. i have done carb cleans for other bikes and have never seen one with liquid in one of the floats. should this be normal for this carb as i can't see how they have filled up (no holes or leaks)..

Oh the bike is a 2000 model nsr 125..

Cheers for any help Thumbs Up

Should not be any liquid in there at all, this would cause the carb to flood.

Its defiantely leaking somewhere you just need to find and seal it, after getting all the fluid out. Forcing the float down into a bowl of water can sometimes give a good idea of where the leak is.

Easiest way is to fit a new float.

Hi,
new float assembly is about 12 quid from eurocarb,
though you may well be able to empty out the leaking one & seal it up with some petrol resistant sealant stuff..

If it's a plastic float and just a pin prick sized hole maybe you could fix it with a solering iron. Just place it briefly on the area where it's leaking, it should melt some of the plastic and seal the hole up.

Yeah its plastics floats so i will see if i can fix it first for him for the time being. i will see if i can fill the hole with sealant if not i will try with my soldering iron as suggesed..

if you use sealant use a petrol resistant one as said above somewhere.
a normal sealant may break down and cause trouble with the jets etc.

I think he means the needle Laughing

hi,
yes, , i mean a " float needle valve". the little pointy thing that attaches to the floats (usually tipped with, is it vitron or something?) & moves up & down (like a piston?) & shuts off the fuel supply.
lose it & its 15 quid for a replacement!

all sorted now so cheers to all that helped out... might make a start on trying to de-restrict the bike now for him... i have removed the intake plate, gonna see how it runs like that. if not much the i will have a look in the exhaust for the restictor bit there.
