OBD Code P0351 please help!!

[RestockMotors]

I am getting the P0351 code on my X22R Max and now my bike is sputtering really rough. I cleanes my fuel injector, tmap, and replace the spark plug. Could this be the fuel pump or something less grueling? I tried replace the tmap and I barely started (ruled out). I purchase a fuel injector, the oem injector has 4 holes and the replacement came with 2 (shipping error) the two hole injector barely ran right (ruled out), cleaned the connector to the fuel injector ( still sputtering) I ordered a new pump that will not be here for a few days. Any ideas as to what may be the issue? I usually use the ngk Iridium Spark Plug but replaced it with a regular copper (oem). Please help!

Have you checked and adjusted the valves yet? These engines usually come set with the valve lash set on the tight side. Check and adjust them before you throw anymore money at the bike. Yu will be surprised at how many people fight tuning a bike when all the time the valves were out of spec.

Thanks Jerry! I have not checked the valves and I am not even sure how to start that process lol. I will look on YouTube and see if anyone has done it yet. Thanks again!

You can look for any video on the Honda CRF230F. Same process and valve clearance.

MANNNNNNN! It was the damn Battery Terminal (positive) and the ignition coil cable lmao! I feel really DUMB right about now lol Because my OBD Reader stated it was an ignition coil issue but looking up a fix was to no fault lol
