Agree with all Axy said.  Did you clean your battery connections when you changed the battery?  I would look at those plus the frame ground plus the starter and relay connections first.

This is a remote possibility but, if some small metalic object like a strand of wire fell into the phone charging socket that could possibly do harm.

OK guys, I'm on track.

Issues found so far:

- Both small tubes were off the air filter house
- Partially damaged oil pressure sensor wire
- Torn wire around the cylinder (I have no clue what that is, posted image)

Do you know what that wire is?

I guess someone tried to "fix something" on the bike and did not care about properly fixing the cables, so they were tense and eventually got loose, or torn.

The big pic link is screwed, fix it... I've loaded the pic by copy/paste of the link.

I've spent 15 minutes looking for this wire. You owe me a mineral water (don't drink beer!) :) when you come to Croatia.

It's "heater carburetion wire coupler."

On the other side of there are "throttle position sensor wire" and "auto bystarter wire".

For unknown reason, I was placing you somewhere in USA. :) :) :)
I hope you will nail this one and fix it. Neighbor. :) When you decide to switch Balaton vacations for some Adriatic sea summer relax, we can toast with a nice bowl of betyár gulyás:)

Hi,


Just want to follow up on what happened to my scooter. I ordered a new Dr Pulley variator set, but it did not cure the problem. I also checked the wiring and the electric components, but no change there either.

I took the scooter to a local mechanic, who specializes is scooters, as the Kymco dealer was clueless. It took him half a day to figure out what's wrong with my bike. He checked the drive train, adjusted the valve clearence and engine timing. Then he took a look at the spark plug... It was all white. He disassembled the carburetor and immediately noticed that the stock main jet was replaced. The part installed was probably from a small scooter with a part nr "KY B6". He replaced it with a standard piece.

Why the previous owner did something like that is beyond me. I bought the scoot from a dealer, so I can't talk to the guy.

My scooter works fine now. With the Dr Pulley set up it really flies and no longer feels like an underpowered 150cc bike. I'm all happy now :)

I hope it may help some people who have problem with their scooter. I was told that the GY6 engine is bullet proof, but very sensitive to fuelling.

Thanks for all the help and info. I have a much better understanding of scooters now.

Wow, that's incredible.  So happy your new mechanic got to the heart of the problem.  :)
