Have a 2010 efi yfz450r. all stock brand new built engine. Owner was running t4 on it. Where I live it’s hard to find. I’m trying to either go to 110 or 93 pump. Should I be able to drain fuel and just run 110 or 93 without messing with the programmer? It has a blaster FI on it. I owned a trz450r beforehand and it was bone stock so I’m not used to all this programming stuff. Thanks in advance
