17 Axys dies when pointed to the sky

[Pickin’ Boogers]

When blasting through a wind lip, or wheelie-ing over obstacles or convexities on a hill climb, etc. My otherwise strong running Axys just plain dies. It's pretty instant - not like it sputters then dies - it just cuts out immediately. Once it's back on the ground it starts right up (pull start).

Clean relays, good TPS settings. Fairly basic mods: SLP pipe and can, TSS bypass for finger throttle, Pro Armor tether.

Thoughts?

I’d be looking at the fuel pump pick up or obstructed fuel tank vent. Or loose/corroded stator wiring connector issues

Assuming this is not what you're referring to, but they can do that when low on gas.

disconnect your tether and see if it still does it...thats my bet. start with the easy tests.

I don't know if this could happen to the Axys but a friends Cat did the exact same thing years ago. He had hit a nasty hole and the impact swung the fuel pick-up at the rear of the tank up around the fuel pump where it got lodged. After that whenever he was pointed up hill it stalled.

It's happened with both a full tank and partial tank of fuel. Seems too instant to be a problem early in the fueling system - how long would the motor run at max revs if I cut off the fuel before the pump? Is there enough fuel already in the system to run for at least a few seconds?
