Welcome Kymco Owners!
Most decent size towns nowadays have fuel-injection service centers. Injectors are cheap to clean, usually while you wait.
This might be for our humble "plastic" injectors, but when it comes to car/ diesel injectors, special equipment and knowledge is neccessary.Certain injectors have to be dismantled and rebuilt under liquid (diesel etc) to function.
what is this black magic you're discussing...fuel injection?
Good grief - I hope not! The Kymco injector is just a little plastic fitting with a stainless nozzle! It takes about 2 minutes to replace Example: https://www.ebay.com/itm/KYMCO-MY-ROAD-700i-FUEL-INJECTOR-/143668016582
