Power issues, looking for advice

[Skeet808]

I just bought a kymco agilty50 2018 second hand. Everything in the engine bay looks clean. The problem I'm having is with the throttle power. On flat land the bike runs but only if I rev it continuously. The bike turns off if its idle or attempting to go up any hill. Unfortunately I dont know much about bikes yet. I'm wondering if it might be a fuel filter issue, air flow or what? Thanks in advance for any help I can get

Perhaps you can start with the simple things first.  Hopefully you have good fuel in the gas tank, then take a look at the sparkplug for any noticable issues.  Follow thru with carburetor cleaning and/or adjustment of air fuel mix as well as idle.   And please change the oil regardless of the mileage it may currently have.   Everything mentioned above is readily available via YouTube video tutorials.   Ride safe!

Pay close attention to the jets when cleaning the carb.  It's likely the idle jet (or pilot jet, as some call it).  It's about .3mm diameter, and clogs easily, and then won't idle.
