My 2000 yz 125 keeps flooding... i can have the gas off and no fuel in the carb and i kick it once or twice and then take the spark plug out and it has gas and oil on it... every once in a while itll...

The crankcase is full of fuel. Pull the plug out and kick it untill the fuel clears out. If your float stuck in the carb while the gas was on, it will fill the whole crankase with fuel. Check out the carb to make sure the float valve is working after you're done. Good luck!

My aprilia 125 moped will not start, there is a spark at the plug, stinks of flooded fuel, it's soaking the plug when kicked over, what's problem?

Sounds like the engine is flooded with gas.Turn the fuel off if you can.Remove the spark plug and move the wire away from the spark plug hole.Now turn the engine over like your trying to start it.See if gas comes out spark plug hole if yes engine is flooded.If it is flood that bad your exhaust will have fuel in it also.You should get a new spark plug before trying to start it again.If gas does not come out the plug hole.Install the new plug and try starting it with the fuel off.Hope this helps.

Yz 125 2001 model. i went down to the garage and kickstarted the bike she fired up no problem then the engine cut out after a minute now the kickstart is real heavy too push down and will not start, any...

Sounds like the piston seized.
Pull the spark plug and hand crank the engine if the piston moves up and down with little effort your ok but if you have a lot of resistance top end rebuild needed.

On my yz 125 my kick start is jammed

Were you riding it when it jammed because that could mean the that something is sized inside the motor, like the crank or the pistion

2006 yz 125 breaking push rod in clutch

That is a bit strange. Did the previous owner install stronger springs than the stock ones? Compare the effort to pull your clutch handle to what it takes on a new 125. Be sure you have clean 10w40 motor oil in the gearbox. No synthetics or special additives. Replace the rod and the lever assembly. The rod, lever and oil should eliminate the problem assuming the springs are stock.

Can I get a “very helpful” rating on this answer?

Try fitting a new spark plug.

While riding my yz 125 it just died and won,t kick up again

  • If a hole in the piston then install new piston and rings. Next, clean the carbon off the head and install a new head gasket.
  • If cylinder wall is scared the piston has seized up. Pull the cylinder off and take it to the dealer. Have them bore the cylinder and return it along with a new oversize piston and rings.
  • While at the parts counter, get a new stock spark plug and a supply of Yamalube Two Stroke Motor Oil. You need to add 4 ounces per gallon when filling up. This will be a 32/1 gas to oil ratio. NEVER ride the bike without at least the needed 32/1 mix.
Please rate the solution as a "FixYa" if able. Thanks!

Jamed kick start

Sounds more like a seized engine to me. When a kick starter breaks it will be when you're kicking it. If the engine died and the bike doesn't turn over with a kick it's probably locked up. Try pushing it back and forth in a higher gear and see if the engine turns over when you let out on the clutch,
