Issue … A 2017 Yamaha quiet tech.. runs great at 21 mph on flat but slows on incline .. going over bridge at Spanish Springs slows to 5 or 6 mph on steep incline .. is this normal or is my belt needing change etc ? thanks

Going up the bridge going lug engine down at low rpm, the clutches are going to be in low speed condition due to low rpm and no centrifugal force to throw clutches in higher speed ratio. So, yes the cart can not accelerate on steep incline cause the engine can’t rev up enough to get clutches out of high torque condition, due to engine does have enough HP/torque to turn clutches at higher RPM for the clutches to change gear ratio.
It you stop on very step incline the belt going to squeal (slip) till the clutches kick in. It you do this often it will wear belt out prematurely.
