Check/replace your fuel filters, put a pressure gauge on the rail if that doesn’t show a drop, swap injectors

Take 5 and slow down.
Is it Injected? Does it have Cats? O2s? What engine?
(Sorry, I haven’t been following.)

Yamaha YFZ450. No cats. 02 sensors are fine. Swapped injectors. Checked the tune. Motec is running fine. Leak down test showed nothing.

You ran it with a pressure gauge on the rail and a go pro watching when you gave it throttle with load?
What engine management are you running?

Damn! That does point to a possible software glitch.
OE ECM?
