I've been having all kinds of cold starting issues. Enough so that I'm wondering if I purchased the wrong scooter. During the summer, it ran and started like a top. Once below 40F though it has been a real challenge. It feels like the starter isn't getting enough juice to turn it over fast enough. I went to a $200 Lithium battery, new spark plug, new air filter and that did not fix the issue. I left the met box open and it drained the battery and now it won't take a charge. I'm feeling like I just tossed out $200 by leaving the met box open. I want to do a idle reset but need to make a decision on my battery first. I'm finding that beings they aren't widely sold, local battery places don't want to give me any ideas on what to do with it. It's a Shorai and contacting support is my next move. This starting issue is really ruining my scooting experience.
On another note, once I get it started, it seems to have no problems starting again . . . . . until the next day.
Bless your heart Wayne....there were a couple of us concerned for you early on, when you became interested in that 500...only because it seems to be
the one KYMCO scoot which owners too freq report starting issues.
I know how much you love your scooter hobby - and how very particular you are in keeping it in tip-top condition.
You also display a good head for sorting any mechanical issues - real or imagined (the latter - like myself :-) - shoot, you, like me, just want and expect our machines to perform as advertised.
We think we know that KYMCO EFI'd scooters need a very healthy battery to start.
Did Kymco not give the 500 a starter with enough grunt to light a 500cc single pot on cold days?
Is the recharge system not up to the task.
I got nothing....
But to your $200 battery: is it providing significantly more CCA than the stock battery?
My NSS300 Forza came with a YTZ12S (YUASA) battery - CCA 210, 1.1 amp.
My Burgman 400 and 163cc Kymco came with the same small YTZ9 YUASA - CCA 135, 0.9 amp.
I switched the Burg and the LIKE200i to the better YTZ12S YUASA.....because I ride distances in very cold weather, & both have EFI....and I like the reassurance of the more powerful battery. (VIVO told me a long time ago to put in the biggest battery that would fit. I did, they do.)
I did a little trimming of the hold-down cover to fit those batteries, but that was all that was needed - measured carefully and saw that they would fit. The YUASA.com site has the measurements of your stock battery....so you can find a better battery of the same size case & connecting types.

The injector on my LIKE was about $70 - but doubt it is something as simple as a clogged injector.
I bought a stick-on engine block heater (oil pan actually) pad that you plug in to an outlet yrs ago for my old VW Jetta sitting out in the cold. Famers use them too I think. Made starts at 0 degrees easier.
Darn....sure hope you can get it sorted....that big engined scoot is probably a blast to ride.
Good luck Wayne....hang in there!
