Hi, i have a 2022 390 and i want to install fuelx to fix the lower revs.
i have a stock exhaust because noise is heavily regulated and i don't want police to stop me everytime they see me

I may or may not install a openbox lid but if install it will the stock injector be enough?

Saw in a post that with an exhaust system and open lid stock injector isn't enough.

Thanks
Ahmet.

Hi Ahmet, Im not knowledgeable on these things but Moto Mirius on here recently posted this video on air box modifications and the need to add more fuel using a fuel X or similar. He has produced two videos, here is the first


Hope that helps

I have a 2022 and put a FuelX Lite on with 23 miles on it. The change was exactly what you are looking for. Because of cold and snow I only have about 45 miles on it now. but the change was instantaneous and is supposed to get better with more riding. It probably took me an hour to do it, but could probably do it in a half hour now. It is pretty easy.
