So I have been building a 1980 XS650 for the last 2 years. Every time I think I am close to being finished something breaks or goes wrong. I just finished rebuilding my motor and put the motor back in the frame hooked up all my electrical and tried to kick it over but I am not getting any spark.. I have run a few checks and it seems that my tci box might be bad. My question is I want to put a new Pamco ignition in my bike but I am not sure if I need the basic system or the ultimate system.. The only difference between the two seem to be the advance rod that comes with the ultimate.. Can somebody please let me know if the advance rod is something i will need? Or can I just get the basic system. The extra $50 is not going to break the bank I just need to know if I need it or not.. Thanks
