Intermediate Sprocket Tightening Sequence
Note
♦
Always replace the intermediate sprocket. Otherwise the
backlash will not adjust itself and it could result in engine dam‐
age.
♦
The new intermediate sprocket has an anti-friction coating that
wears off after a short period of use, which automatically ad‐
justs the backlash.
