Running issue solved!
My scooter's throttle position sensor failed on July 4 (or 5th, can't remember) 2014.
Scoot went in for a 2nd dealer attempt to fix on Sept 26th.
Today, Nov 8th, I picked it up from the dealer and rode it for an hour, at all speeds.
The scooter is working perfectly again.The dealer obtained these parts from KYMCO USA, and installed them:
1 Module ASSY ECU
1 Seal THROTTLE ECU
All work (this time) was carried out under warranty, no charge. The parts are new & confirmed by eye-balling them and comparing with photos of the orig. parts.
I noted that they did use fully a half tank of gas while they had it (I filled it a few hundred yards down the street before giving it to them) - so they did give it some thorough bench & road testing.
I must say that once KYMCO USA was brought into the picture - for the most part they did do all I could ask to get my scooter fixed.
I'll run it a few more days, and if all is well, I'll give the area KYMCO service rep. a big thank you for his intervention.
This LIKE200i is a
very peppy scooter on city streets.
The EFI fires my scoot in all kinds of weather and temps and has never left me stranded in 7000 miles.
The brakes are superb.
I've no complaints with the build quality of the body or engine....though I did quickly upgrade the tires to Michelin City Grips. I would recommend staying with OEM Kymco parts for their quality.
The scooter is, I think, very easy to service (spark plug, valves, injector, coil, fuel pump, belt, clutch, rollers, engine & gear oil changes, brakes, bulbs, switches)
Only after putting nearly 3000 miles on a longer, heavier, more powerful scooter with larger tires and twin headlights did I become so aware of the limitations of the LIKE. The harsher ride quality differences are due I think to it's wheelbase, weight, engine & tire size and lighting.
I think it provides very good value for about $2500 OTD. Before I'd spend very much more than that - I'd be looking at bigger, new/left-over or lightly used larger scooters. My impression is that Kymco makes quality scooters.
I am happy to have this LIKE back running well & in the garage!

{It all seems like too many words for a simple fix. Thanks for all the support from so many members!!}

PS: Karl, I will get your scanner in the mail ASAP..... I'm going to run the scoot a few more days - but I'm not going to test it with the scanner if all seems good. Then I'll return it with some nice donuts taped to it , or something, for your kindness.)
