Changing The Clutch Oil; Repairing The Lights And/Or Horn - MINSK Repair Manual

If you cross a river then expect to loose your brakes for a while. Remember to
pump (squeeze on and off constantly) your brakes to dry them out.
Changing the Clutch Oil
Fresh oil in the gear box and clutch will protect the gear cogs, clutch plates and
gear changing parts from unnecessary wear and will make shifting the gears
easier. Most people neglect to change their oil regularly allowing grime, water and
dirt to foul their Minsk's insides prematurely.
To replace the oil, first remove the stubby bolt on the top of the clutch cover
above the kick-start pedal. Then empty out all the oil by undoing the #17 sump
bolt underneath the engine. The oil will pour out all over the place so have a
container handy. If you have a hard time removing the sump bolt then use your
sparkplug remover tool as it is the same shape.

Shake the bike and lean it from side to side to make sure all the oil gets out.
Then put back the sump screw and fill the housing with some petrol – 500 ml is
fine. Put something over the hole where the stubby bolt was to stop all the petrol
from spraying out and then start the bike to let the petrol swirl around the clutch
and gears. This will wash out all the muck in there. Then remove the sump bolt
and empty the dirty petrol via the sump hole. Lean the bike from side to side to get
it all out. Then give it a few minutes to dry, return the sump bolt and refill the
housing with a little less than a whole can (700ml) of oil. Change the oil every two
months or so. If you have been driving the rain for extended periods or have
crossed a few deep streams then do check that the oil is not white – this means
water is mixed in – and change it if it is.
Repairing the Lights and/or Horn
All the lights and the horn are on the same circuit and get their electricity from
the same four coils in the generator. Therefor, it is possible to have electricity to
the sparkplug but to have lost it for the horn and lights. This means you will be
able to drive the bike but you won't be able to use various combinations of the
front head-lamp, the back light, the horn or the indicators.
