stalling prob on 50cc

[sharp7277]

I bought my little nephew a 2000 Kasea 50cc dirt bike ( I know its korean junk but it was only $600 brand new). It runs good except when you lean it to the side(turning) then it wants to stall. I thought it may be sticking floats so I took the carb off and cleaned it out really good and everything seems to work just fine in the carb. Has anyone else ever had a problem like this? Im afraid he will spray paint my CRF 450 pink if i dont get the bike fixed for him! thanks.

I had a similar problem with a JR50. It has a nonsymetric float and the float went bad. I could get it to run but it was lean when leaned to the right and would flood when leaned to the left. A new float solved the problem.

Where did you buy a new 50 for $600?

I guy was selling a bunch of them at his lawnmower shop and i offered him $600 for the 50 and he said take it. It has a JR 50 motor on it. But dam its like pulling teeth to get parts for it!

It sounds like the same problem I had. The local Suzuki dealer said that the float was not available seperately and would sell the carb housing with float for $90. I found a new carb on e bay for the same price. However, after buying the carb I found a source for a float. Go to www.bikebandit.com and look up carb parts for a '92 JR50. It shows the float for about $15. The pivot shaft is peened into place but I'm sure you could remove it. To replace the shaft you could always peen it back, use epoxy or drill/ tap for small retaining screws. Before swapping parts, you may want to experiment with lowering the float level until the problem goes away or it gets too lean.
