After years of off road riding I sold my old XR600 a few years ago, it was an excellent bike, but age and reality caught up with me - kick start 600cc bikes (especially in cold climates) are for younger people. So I recently had the opportunity to purchase an '85 vf500 interceptor for $200... How could I resist? It's all there and in pretty decent shape considering it was stored in a guys woodshed here in Maine. I was inclined to believe him when he told me it was running last year but he broke the starter switch and choke cable. So I was able to replace the choke cable without much issue, the starter I have at the moment rigged to try to fire the bike up. This is where I'm looking for some suggestions - I have no spark. I've read several posts on interceptors without spark so I have several questions from others with more experience. The previous owner broke the starter switch so I just use a piece of wire to jump that circuit (see photo, I jump yellow/red to black/red) so the starter cranks - if I can get it to fire I'll invest in a whole new on/off starter assembly. For now, if there's something else which should be jumped to get it to fire, please let me know. On my coils I have 2.7 ohms on the primary side and 13.7 ohms on the secondary side, after reading through the Clymer's manual I see the primary should be 2.8 ohms and secondary 2100 to 2800 ohms. If this is the issue, shouldn't I at least see a faint spark on plug? I see no spark when I crank it. Again I'm interested in any suggestions. Another interesting issue, my fuel pump is not running when I crank the engine (I have unhooked the pump and it pumps fine when connected directly to a 12v battery), I had read on one of the threads here that the fuel pump will not run unless the coils are functioning correctly. Is that true? I could not find a reference to that in the Clymers manual. I would have thought the CDI might control the fuel pump and maybe two bad CDI boxes could be the issue. So I'm looking for some suggestions of how to approach my no spark issue. Thank you for any suggestions.
