Mini Thunderbolt 1003 monthly test and annual servicing.
Yearly visit to service the mini 1003. This year we (mrtruealert and I) re painted it a more accurate “C series yellow”, made new horn supports, and fit a new flywheel to the ISC. The pitch issue which can be heard has been fixed by switching polarity at the ISC and now runs smooth. Also I tightened the belt to the blower an oiled the motor. Over all it was a fun trip and the mini Melvindale bolt is good for another 100k miles! As they say.
