2017 fuel injected Yama Zuma 50cc, idles fine ok bogs on acceleration

My moped will start an idle fine, but when ever you try to accelerate the engine bogs down. It is fuel injected so no carburetor to check. I drained the gas tank whenever I purchased it and cleaned it out ran some new gas and fuel injector cleaner through but still having the same issue. Any thoughts or ideas?

Answer this question I have this problem too

Is this a good question?

Hi @zumabenz1

If you don't get a better answer here's a link to the service manual. Unfortunately you have to purchase it but in the end it may be worthwhile to do this.

Hopefully this is of some help.
