I've covered every obvious base. Good compression. Good spark. Sea foam blasted through the carb and jets cleaned. Air filter noted and given a good sea foam rev up for a few minutes. Fresh gas with gas line anti freeze. Brand new battery. Plug seems fine and no dicernable shorts in the plug line. Hoses are clear but it takes a few cranks to get started, idles ok but dies easy on throttling. If you have any experience with FI systems like this then please contact me. I'm just off beach ave in oak bay. And will be happy to pay for your time if you can make some progress. We can talk first. Please TEXT first. Thanks!! 2009 Kymco Frost/Yager 200i Km
