After first hour of use, check the state of the clutch pads. Review the clutch

After every clutch slipper shoe replacement it is necessary to adjust the clutch
springs. To increase the revolutions, and feel the clutch working, tighten up
the adjusting bolts and to engage shoes at lower revolutions,loosen the bolt. It
is important to adjust all the springs to the same level, so the clutch lining
wearing is even. The index for adjusting is the length of the spring, which
should be 21,00 mm. The length is measured from the bearing surface of the
clutch shoe to the spring plate.
