Earlier in the year myself and the Swinburne Motorcycle club set on a task of finding a cheap roughed up bike and as a workshop trainer to demonstrate basic servicing on. After a few weeks of searching we were contacted about this gem that was in need of some TLC. When I brought it I was informed it hadn't been started/for many years/(cough decades) and was missing a few parts including the CDI. After we took it it back to the garage and started drawing up a battle plan we were biting our fingernails wondering if we had bitten more then we could chew. Our first issue was the state of the electrical and ignition system, we hadn't been the first to tinker around with it and after 30 years was showing its age. The show stopper was the missing CDI unit, none of the wreckers had seen one in years, buying a genuine new one would cost over $500 and the aftermarket ones for half the cost were not compatible after inquiring. As we had blown our budget acquiring the bike and transporting it back we were forced to improvise! Google was little help, only finding one other person on the interwebs who knew how the ignition system worked (then quickly gave up and brought the genuine box) we knew it would be tough. After weeks of searching and trying our best to work out the ignition system a second hand service manual popped up on ebay giving us the answers we sought. This clarified why our AC CDI blew up and refused to let off a spark. Knowing this and the fact the bike (should have a mechanical advancer) he hit up ebay for the a $34 DC CDI with 6 pins which we could stamp a new plug onto. This turned out to be a blue Best-Tech CDI designed for a 250cc ATV. Blue Wire: Pickup + Yellow Wire: To Coil Red: 12+ Power (kill switch) Black: Pickup - / Ground Green: Ground Crudely jammed in for testing purposes we tried to turn over the bike without success however got a pop after spraying half a can of ethanol through the carb which inspired confidence. Although being assured the carb had been cleaned by the previous owner I took it off and spent the evening cleaning it out and unclogging the jets which had pretty much been cemented shut. After a day at work psyching myself up on getting the bike turning over I raced home and bolted it all back together for the big moment. Within 20 seconds it fired into life...then stopped and after a little bit of cursing started to idle. While taking us a few months, this is just the start!
