I've just finished installing my pamco kit with the e-advancer. i've wired it up as per these instructions
http://www.yamahaxs650.com/installation.htm
I tried to fire it up tonight but it wouldn't start. i got about 3 backfires when i first started so i moved the timing a little one way and then the other but no luck. after that it wouldn't even backfire. no life at all. i double checked my wiring and then i checked for spark. it is infact sparking. I've tried moving the timing all over the place but no matter where I put it it doesn't show any signs of wanting to fire. I have the coil bolted to the frame via the home depot grounding clamps but i haven't run an additional ground to the coil. is it possible that the coil needs a dedicated ground wire running to it? like I mentioned it does spark but perhaps its weak? I had the bike running pretty well about a 1-1.5 months ago but i haven't started it since. i didn't fire it up before i installed the pamco so im not sure if something else has possibly developed in the time it was sitting? it has good compression, I had the carbs apart for a cleaning just before the last time that i ran it and I rode it for 20-30 min before i parked it and it was running well except for the mechanical advance hanging up but since i was going to the pamco kit i didn't bother messing with that at the time. I drained the fuel tank and put fresh gas in it right before my last ride as well. the tank is pretty low on fuel now but I should think it's still good after only 1 month or so of sitting. I also pulled the fuel lines off the tank and fuel poured out so it doesn't appear to be obstructed or out of gas.
it's a 1977 xs 650. It has a fresh battery (about 2 months ago) AMC regulator, radio shack rectifier, new alternator rotor and now the pamco ignition. Any advice would be greatly apprecaited.
