Welcome Kymco Owners!
I use to own a 2006 Kymco People S200 (163cc w/ a carb.) & I always kept it on a Deltran Battery Tender Jr. float charge (regardless of the weather) I used Stabil & Startron ethanol fuel treatment every time I filled-up. Even when it was 40+ degrees out, she would start within 3 pulls. What Kymco model do you have? If it's fuel-injected, you're much better off!
No problems so far with my 2009 XCiting 250 with fuel injection. We've had a couple of mornings in the mid 40's and she started right up...first push of the button. No additives, no battery tender...but then I ride most every day. Keeping my fingers crossed as this weekend may hit 32 in the morning.
Thanks, I think the fuel injection has an advantage over the carb. and Vivo I don't think it gets too cold in the islands unless your in the high hills.So far so good with mine but I don't want to find out the hard way one night.
Get really good warm gloves or over-mitts, your fingers will freeze in winter even with your normal summer gloves on.
My tuned up A50 starts on the button every day i start it within a sec normally even if i've not used it for weeks. Was 1°-2°C yesterday here at 6:40am when i went to work, had been riding my 125cc scoot the last few weeks so the A50's been sat in my garden uncovered and unused. Put in the key, pressed the elec starter and she fired right up within a second no probs. I never give it any throttle ever when starting it, once it starts i leave it while i pul on my helmet and gloves then off i go Got to say i have never had issues starting mine even in minus temperatures when theres frost and ice all over it.
