Improving The Clutch Mechanism - MINSK Repair Manual

the clutch lever meaning the clutch pads will slip. If you do not tighten the screw
enough then the clutch lever will be too loose and will only engage the clutch pads
when fully pulled in. The gears will then be hard to change.
To test your work, put the bike in first gear with the engine off. Then squeeze
the clutch handle and see if you can push the bike forward. If you can then things
are fine but if you can't then the screw needs to be tightened more. If you have
made it too tight then the engine at high revs will slip, making a RrRrRrr sound.
Just play around until you get it right. When you have found the right position,
tighten the #13 lock nut to keep the screw from moving out of position.
Improving the Clutch Mechanism
When the cable pulls the lever arm up, the large screw thread pushes a rod into
the clutch plates. You can make this action much easier on the Minsk by cleaning,
greasing and protecting the thread/lever mechanism.
To do this, remove the generator cover to reveal the drive sprocket, the
generator and the clutch lever mechanism. Disconnect the clutch cable from the
lever arm, unclip the spring and then unscrew the lever arm. Clean the large screw
thread on the lever and the thread in the cover with petrol and then grease them all
up before putting everything back together again. Do not forget to put the black
detachable mudguard back into place and do not loose the ball bearing between
the screw and the rod going into the clutch. If the small spring on the lever arm is
stretched then replace it in order to give the lever arm better spring.
Always make sure that the three screws which hold the generator cover to the
bike are tight. If they are not, then the whole process of pulling in the clutch cable
to change the gears will be made much weaker as the force will go to moving the
generator cover outwards rather than the lever arm upwards. You will then grind
through the gears no matter how hard you pull in the clutch lever.
