[QUOTE="Lucas Magneto, post: 169699, member: 5591"] Hi all, need help trying to identify ignition system fitted to my 1951 Rapide. that I am currently recommissioning. This bike has not run since 1981,so I expect that this is most likely 70*s wizardry. It has an optical trigger and a home made actuating shield (see pics), looks to me like some kind of CDI black box of a type of I've not seen before and using single nippon denso twin lead coil to fire the plugs. The unit appears to work when wired up and tested statically, however the spark wasnt what i would call fat blue crack, more of a slightly weak blue with a tinge of yellow ! I was wondering if it is worth going down the route of trying to get it refurbished or more likely replace with a more modern unit. I have had experience of the self generating BTH mag in KTF format on two Tritons one excellent and one bad, a ceased bearing spinning in the housing after one season, puts me off a bit now. I run a Trispark on my T150 Trident and found it to be excellent and so easy to set up but there are others out there that claim to be just as good or better for Pazon for example, however, I only have experience of these on parallel twins that don't have the same characteristics of 50 deg Vtwin. As all of these options are not particularly cheap, I would like to hear some of your experiences or recommendations with any of the above systems to help me decide which way to go regards[ATTACH alt="20230220_164522.jpg"]56683[/ATTACH][ATTACH alt="20230220_163914.jpg"]56684[/ATTACH][ATTACH alt="20230220_164619.jpg"]56685[/ATTACH] [/QUOTE]
