Modern Buddy

What's up everyone, I'm new to the forum. Here is my issue. I have 2011 black cat about 6500 miles Island miles here on Hawaii. It all started when I was coming home from school. It ran fine that morning. But when I started it and try to pull off it lost power. I tried again and it lost power and died. So, I got it home and looked at everything and everything looked fine. But the problem persisted. Being no mechanics that work on this type of bike*PGO*.I'm on my own. So I got a new engine from the states put it in and I'm still have the same problem. I checked the the vacuum line and fuel line. When I sucked on vacuum line fuel came out of the fuel line. Remember I have a new carburetor and spark plug with the engine. Thanks in advance

Update tried running without exhaust pipe no luck. Also tried with had cap off. No luck

With a new engine in and still the same issue, I am going to venture a guess that your problem lies some where in the electrical system.

You said that the problem still happened with new engine? With the same carb? was it too lean jetting, check it out mate...

I agree with Agrogodness. Focus on your electrical system. If the symptom only occurs in wet, rainy, humid weather, then the first suspect should be your ignition wire and coil.
