Lowering the brake pedal …
The brake pedal was positioned much too high after I lowered the footrests, so I had to lift my right boot off the footrest to reach the brake pedal.
It was possible to lower the pedals engagement point at the brake master cylinder, but the excentric adjuster could not be adjusted enough for the brake pedals new and lower rest position.
Problem solved by drilling and tapping a 4mm bolt into the brake pedal 🙂
