The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.

Checking servo is working

Turn servo pulley wheel full in one direction. Then turn ignition power on and pulley wheel should reset to centre. Try other direction. If both self centre then servo is good.
There are plastic teeth inside the servo that sheer when the valve seizes. Some folk have swapped the gear over 180 degrees and successfully used the other unused area of the gear wheel. Also R1 gears are rumoured to fit

The Black widow pipes are straight through (no valve).

The YZF750 EXUP servo has the same gears as the FZR1000 EXUP

The 98/99 R1 servo is the same as the YZF750 servo 👍
