Ok so for these past few weeks I`ve been careful with my fuel levels and still have the starting issue. It does always start after doing a couple resets and playing the throttle.
My main concern was whether this was a sign of things to come and that something was about to break down on the bike and that sometime sooner or later my luck would run out.
My next plan is to pull the plug and have a look. I changed it last summer and have put a few thousand miles on it but maybe these Kymcos are plug eaters.
In the meantime, I`ve found that the computer reset is about useless really, I can do it 4-5 times exactly as described in the service manual and it will eventually start but starts hard, the better thing to do at least in my case is to hold the start switch and let it roll over a number of times then play the throttle a little bit and it fires right up.
I`m also going to order a new battery as agilebda mentioned.
One thing I`ve noticed right from the beginning is that this Kymco tends to roll over a few times before starting even on its best day. My SYM HD200, which has a carbureted engine would start within a half a second of hitting the start switch. I think maybe these stock batteries are a bit weak and sitting in the heat drains them just enough to make starting harder.
