| Overtightening of the cylinder and cylinder head
nuts will cause malfunction of the Sherco 2000 engine. Check the following settings to
make sure the bike is set-up properly. Incorrect tightness settings will cause a loss of
performance. Also, if there are clutch dragging problems, it could be that the clutch axle
is overtightned, please check the value in case of a problem. |
