Yamaha shop manual shows TPS is to be set @ 5K on rev counter, motor needs to be up to temp & idle set @ 1,100rpm.
Never come across setting it to 10K.
If it's anything like Honda, it's a reset procedure so ECU can see where throttle butterflies are in a zero position ie) closed throttle, so ignition map is its optimum rpm range.
Suppose you could always try the 10K position after the correct 5K position & road test back to back on same test route.
Before doing any of the above, ensure the motor has no known gremlins.
Exup is serviced & correctly setup.
Plugs in good order & set correctly.
Carbs balanced.
Or you're just wasting your time doing any TPS position testing. :thumbup
