    Thank you bro. Have watched several videos. Many say basically almost similar things. LOL but definitely do not explain it as well. Everyone thinks everyone knows exactly what they are talking about like we are all dirt bike masters. LOL Thank you for explaining so it's understandable easily. When you do something often or daily things become easy.

    I had my 1985 Honda 350r XL enduro restored cost around $2500. Rode it today for about half an hour. Went to get on it and ride right now, and it wont start and theres fluid coming out of a hole every time I kick. Just got it out of the shop. However, I may have not closed off the fuel when I wasnt riding it. Could have been some days. Any idea? This is my first bike too. Great condition.

      Sounds like the needle might be sticking open. You could try blowing compressed air into the overflow hose, otherwise might have to take the float and needle off and clean the seat with a q-stick.

      Hard to say, but the popping could be from incorrect cam timing or jetting that's too far off. I'd double check the cam timing - if it's off too far then you could bend/break a valve and have to rebuild it again...

      Make sure you got all of the water out of the engine/exhaust/intake/carb/air filter. You might have to flush it out.
      Then make sure you're geting spark, fuel, and air and the engine still has proper compression.

      The gas line from the fuel tank? If so, that needs to be replaced before riding again.
      If it's one of the carburetor overflow lines, that usually happens because the bike was tipped over or the float needle is stuck. You can try blowing a few quick shots of compressed air in the overflow line to see if that fixes the leak.

    I’ve got a KLX125, recently replaced the carb since the old one was leaking from just about every seal on it.

      The needle and seat might be dirty/sticking. It might be fine if you just ride it around for a few minutes. If it's a cheap knock-off carb, they're known to have more issues because the jets/circuits/seals aren't as high quality as OEM.

      @@MotocrossHideout and I’m thinking the floats sticking. When I swapped the carb, I also cleaned the tank and changed out the fuel petcock/filters + put in fresh gas. It ran fine for that day, no issue. Then I stored it (after DRAINING Carb w drain screw, didn’t let it run out of gas). My best guess is it got gunked up from sitting for 2 weeks without gas in there, because I tapped the side with a screwdriver and it started to leak a little less than before. Still a decent trickle, but not a Steady FLOW anymore.
      I’ll probs pull it off later today when I’m off work in a few hours and check it out. Hopefully I’m lucky and I can just pull off the bowl and blast the float + seat with carb cleaner since it’s all brand new, and only sat 2 weeks.
