    So I got the 125 running. Then I ended up letting it sit for 2 days. Got it out to make sure it runs. And when I started kicking it over. Something started leaking off the exhaust. And I have no clue what it is. And not to mention it won't kick over. I need help I'm clueless my spark plug is like new. A nice color. And when I pulled it out. It wasnt wet. I have no clue what's going on and I need help as fast as possible. I want to get it ready because I'm going to ride Saturday hopefully

    No offense but your post is also confusing.

    "And when I started kicking it over. Something started leaking off the exhaust." This indicates that the engine was in fact kicking over. Or else how did you start doing something it wouldn't do? For something to leak out the exhaust (assuming the stinger or silencer) it usually takes the pulsing of an engine turning over.

    "And not to mention it won't kick over." Next you say it's not kicking over.

    So please clarifiy. Will the crank rotate either by the kick starter or by moving the bike while in gear? If not will it do so with the spark plug removed?

    Off the cuff could your carb floats be stuck? I've seen old bikes with stuck floats drain an entire tank into the crank case and hydro lock when attempting to start.

    It won't start. There is rotation of the crank. When I go to kick start it without any throttle it doesn't have any sound of wanting to start. So I give it a little throttle and it wants to start a little more. But then stuff is leaking out of the exhaust where it connects to the motor. I turned my gas off. I'm not at my dads. And I'll pull the carb off to look at it. But I don't believe it's the floats.

    Ok if by saying "it wants to start a little more" you mean the engine fires intermittently, then you know you are getting spark.

    I still wouldn't rule out that you might be flooded. Weeping around the head pipe is an indication that you have liquid in your cylinder. Try pulling your spark plug and give the engine a few hard flips. If gas sprays out of the spark plug hole or you get an eye watering smell of gas it's flooded.

    If it's not flooded then have a look at your carb. Could the pilot jet be clogged?

    Potential I took the spark plug out and got a big wiff of gas. I gave it a few kicks. But nothing came out. I'll look into the carb and keep you updated. I'll probably post a comment in this thread if it's a carb in the next 12 hours.

    flooded..floats stuck/not sealing. nothing will ever usually come out of the plug hole, it will just keep filling the exhaust and crankcase if its flooding. plug will likely be wet right after kicking and not starting. if the plug stays dry after you trying to start it, you can rule out flooding.
    has the carb ever been off and cleaned?
    its rough being a newbie and having a bike needing alot of repairs, but if you listen to advice, do some reading and pay attention you will learn alot.

    If there's any raw fuel in the crank case it will be to rich to start. The fuel is heavy so it doesn't come up through the transfer ports very easily.
    If it's only slightly flooded you can compensate for the richness by kicking it with wide open throttle to allow as much air in as possible to balance out the richness. If that doesn't work you can try pulling the plug and pushing with the bike in gear. Like you are trying to push start it. You can get the engine spinning faster and longer this way than with just the kick starter. This will often force the liquid fuel out of the crank case.

    I've had a flooded bike spray me with so much gas out of the plug hole I had to go change my clothes.

    push or pulling works well to clear crank but be careful, ground out the plug wire or hold the kill button. dont leave the plug in the cap sparking. i know of two bikes that caught fire this way.

    I learned this lesson. After removing the plug, I pushed my flooded Wr250 down a hill and kaboom, it went up in flames, burning my wrists and forearms. The ignition was left on and just the tiny spark in the plug cap was enough to ignite the fumes coming out of the plug hole.
    Surprisingly not much of the bike was damaged though, seat charred a bit and melted the airbox.

    I have done the same and burnt my hands snuffing it out, not badly , I had gloves on, despite my CO2 extinguisher being within 3 foot of the bike, you don't always think clearly when panicking.:doh:

    Thanks guys. I kicked it without the plug in and boom gas shoots everywhere. It was really flooded I just did an oil change and I'm about to try and kick start it again

    It's still flooding. And I took the carb off and gas is pouring out of the overflow in the carbs is that an indication my floats are stuck? If so. Someone point me to a link to look into it how to get them unstuck or please discribe how to do it. I want this bike to run again. I had it running the other day. Then when I pulled the tank off and the pet cox was offs small flow of gas came out. I don't think that was the two stroke mix. Could it potentially be that the gas coming out of the tank be my problem. I'm so lost rn. I know 4 stroke motors and how to fix them but when it comes to two stroke I'm lost. Any info to help is really appreciated

    Yes, it sounds like the carb float is stuck. They get holes in them over time and don't float anymore, sometime needle gets stuck. Best is to get a rebuild kit with float or replace the carb.

    Google and YouTube are your friends, searching here will give plenty of results too.

    Sounds like you have two issues here. #1 the float needle is sticking. Take the advice given above. #2 you have a worn out and leaking fuel tap. Replace with a new one.
    ALWAYS remember to turn the fuel OFF after using the bike. I made that mistake many years ago and had the same issues you have.

    this being a two stroke, you will not have fuel getting into the bottom end if it floods. two different engine compartments.
    you will definitely need to fix the petcock, and make sure it doesnt flow fuel when turned off and does flow when turned on. the previous advice about the carb will also apply!

    Whats going on is your crankcase keeps getting to much gas flowing into it. Probably gonna have to let it sit with plug out for a day or two and let that gas dry up. It is not going to start untill you get that gas out of there, and its going to do the same thing untill you get the leaky pet cock fixed or your your float needle fixed. Time to spend some money and do some p.m.

    IT RUNS. We bump started it. The kick wasn't spinning the piston hard enough to get it going. So I ran it for a bit and it runs again. Thanks guys.
