If the starter solenoid closes, use a multimeter and check to
see if electrical energy is reaching the starter motor. Note
that the photos shown here are from the TT250; the SG250
motorcycle is similar.
If the starter motor is receiving electrical energy but does not crank, the problem is most likely the
starter motor. The starter motor is removed by removing the two bolts retaining it (accessible from
the right side of the motorcycle, and the electrical connection. If you need a starter motor, please call
us at 909 445 0900.
If the starter motor spins freely but the engine does not
turn, either the starter motor output gear is stripped or
there is a problem in the starter gear train. Remove the
starter motor transfer gear train cover and examine the
gears. The starter motor transfer gear train cover is
restrained by three 8mm bolts. If the starter motor output
gear or the gear train exhibits any anomalies, replace any
defective components. Please call us at 909 445 o900 for
replacement parts. Note that the gear cluster has thin shims
on either side; take care not to lose these. If no defects are
apparent, it will be necessary to remove the left engine
crankcase cover for further troubleshooting.
Place a drip pan under the engine, as engine oil will escape
from the engine during the following steps.
Remove the gear shift lever.
The left engine crankcase cover and the countershaft cover
are secured by several 8mm bolts. Remove all of
them. Note that the bolts are of differing lengths.
