Start the engine using the usual procedure adopted for a cold
engine. Do not be disillusioned if there is no sign of life
initially. A certain amount of perseverance may prove necessary to
coax the engine into activity even if new parts have not been
fitted. Should the engine persist in not starting, check that the
spark plugs have not become fouled by the oil used during
reassembly. Failing this go through the fault finding charts and
work out what the problem is methodically.
When the engine does start, keep it running as slowly as
possible to allow the oil to circulate. The oil warning light should
go out almost immediately the engine has started, although in
certain instances a very short delay can occur whilst the oilways
fill and the pressure builds up. If the light does not go out, the
engine should be stopped before damage can occur, and the cause
determined. Open the choke as soon as the engine will run without
it. During the initial running, a certain amount of smoke may be in
evidence due to the oil used in the reassembly sequence being burnt
away. The resulting smoke should gradually subside.
Check the engine for blowing gaskets and oil leaks. Before using
the machine on the road, check that all the gears select properly,
and that the controls function correctly.
When the machine has reached normal operating temperature, check
the coolant level at the radiator filler neck. Top up if necessary (see
Chapter 4 - Cooling) and fit the cap, then check the expansion tank level.
If the ignition trigger assembly was disturbed and the ignition
timing is still to be checked, ride the machine slowly and carefully
to the nearest BMW dealer for the work to be done as soon as
