Post Possible ignition or fuel problem?
I have a 2009 Kymco Agility 125 with right around 2000 km (1250 miles), and use it as my pit bike at the drag strip mainly. I had bought it at the beginning of 2018 with around 1700-1800 km on it and it ran beautifully for the first 2 months of the race season. One day at the track it decided to not start after already being ridden half of the day, and I went through and checked if it had compression, fuel and spark. Compression was fine, i cleaned the carb and what finally did the trick was replacing the spark plug. After that it rode fine again for a couple weeks and randomly wouldn't start one morning, so I replaced the spark plug again and it ran at my house, so I rode it down the driveway and back again and it just quit. I replaced the coil/wire, cleaned the carb again and even checked and adjusted the valves but nothing worked. So I let it sit for 2 months for the rest of my racing season (season goes from April to October roughly) and I had went out to put it away for winter and it started without zero issues and warmed right up... What could cause behavior like this and what should I replace next so it will be reliable at the race track for me? I'm wondering if anyone else has had experience with any of this, a couple things I'm thinking next is to replace the cdi and/or the auto choke? I'd like to keep cost down and not replace both though.
