Does anyone have a DIY or a thread on what steps is needed to swap the sparky plug on a efi yfz450r. I'm in the process of wanting to change it I don't wanna pull down more then I need to PLEASE HELP WITH INFO

Take the gas tank off. Pull the boot off plug. Take plug out. Reassemble in reverse order.

Seat, rear fenders, gas cap, tank cover, side covers, front fenders I can't remember 2 tank bolts up there, gas tank, drip shield under tank, rubber boot, spark plug. There are caps for the fuel pump and fuel line mounted on the fuel tank. Use your manual for torque ratings because many bolts are torqued to 5.1lbs?? You don't want to strip any threads out. Good luck!

I'd recommend a small amount of anti seize on the plug threads too..
