hi ray, the company that actualy made all the cdi,s for ccm are still going ! over the years i have bought several different types of cdi from them and some second hand from the speedway community, to get the old bike running. one was a new designe with a different trigger set up (still a coil and magnet, but the magnet rotates) this was in 1993. it cost over £300 ! it was powered from the same 1/3 segment alternator not generaring continuos power. the spark energy at kick over speed was very good. unfortunatly the timing advance was hoples. there was not enough range of movement in the electronis. if it was set so it could be started without kicking back, it would not rev. if set to rev it would kick back so hard it would break engine parts ! (putting the kick start leaver through the sole of my boot) they said there was nothing wrong this new ignition and would not repear or replace it. i went back to re chargeable boxes uesing the lucas trigger. i even repared one of the with the help of an rc plane freind of mine. when the last one of these stopped working i un potted the £300 box to see if i could modify it to run with the correct trigger. i have not been able to get it to go. for the last year or so i have been in monthly contact with the origional company to get another ignition. at first they were going to make a new alternator system uesing new inverter technology, to give a more reliable eficent cdi. but i have given up on that and spent the last 2 months trying to sort it out. the ac from the oscillator is over 500 volts when rectifyed it is still over 400 volts dc this is probbably to overcome the compression stresses in the engine ? i may be old fashion with regard to digital or programable stuff but the old technology cdi can work very will. all i need is the power supply !
