Air fuel adjuster screw

Recommended Posts

I have a 2016 kx450f and have been dealing with a lot of popping since the humidity and heat have become significantly higher. I was told to adjust the air fuel screw because i am running to lean. It is fuel injected and anywhere i look online says nothing about these bikes and air fuel adjustment screws.

They don't have one. You need to check your tps and make sure the voltage is correct. Mine was set incorrectly from the factory causing it run an already lean map even leaner. Once adjusted the popping was almost eliminated and the bike ran smoother. Run a search on google about it and you should get fixed right up.

Cheapest and a good way is to send your ECU to TokyoMods, the remamapage for 95 dollars and you can get a map that suits you and without the popping issues 

 

Or if  you getc lucky you can ask if you see someone on track having the remap tool and change a map for a new filter for example
