Look who's home!
Picked up my LIKE this w/e.
Dealer service manager said they "road tested it for 1/2 hour and let it run for an hour, and it ran fine."
He said, "maybe whatever it was has worked its way through the carb."
He said they were only charging me for 1/2 shop time.
$53.
Breifly:
The engine was cutting out severely for over a week, and now so often and severely , I parked it for fear of damaging the engine or myself, in traffic.
Ran 3 to 4 tanks of gas through; used different stations to fill it. Used Sea Foam (service tech said he is "not a big fan of Sea Foam") changed out the coil, lead, plug cap, plug; pulled the injector and soaked it in Techron straight; checked & cleaned all leads; replaced tank vent valve & hoses; checked wiring, fuses, switches, contacts, oils, brakes, exhaust, etc.
On the ride across town to drop it off at the shop (with son following in the break-down vehicle) it stumbled one time...and I could not get it to repeat.
After leaving the shop, and in one more ride, it stumbled one or two times on the road at 40mph within 5 mins of starting and then ran OK. The real test will be to see if it will cruise at 20mph for 1/2 hour without cutting in and out, but must wait to get to that road.
So, nothing is .....
What?
I am really leaning towards a clogged injector. It is so intermittant now, and does not seem tied to any bumps or movement.
I may go over to the wrecked LIKE in the neighborhood and see if he'll sell me the injector.
Runs so bad I park it, walk and bus to work...then a week later it runs better going to the shop.
One of the final things I did was that full strength Techron soak in a pan with the injector. Still cut out on one test ride after that. Then I parked it again.
Also, the dealer does not have the diagnostic plug-in tool from Kymco.
I will keep riding it and report back to you other LIKE owners.
I'll test what I'm capable of with a multimeter....lot to learn in that area.
This dealer back up had a lot to do with why I've moved on to a Honda. 4 dealers in the area.
If it continues to run poorly I will go down and have a chat with the owner of this mega power sports store. No other Kymco dealer around. I am not the least surpised that these guys found nothing. I explained at length the symptoms to the tech. He said, "running bad, got it."
Still under warranty.
