My stock 1980 tci coil and ignition box finally gave out so it's time for a pamco. I'm currently installing the Ultimate Pamco electronic ignition kit with e-advancer/ignition coil kit Part # 14-0907 from Mikes. I know this has been covered 100 times before but I'm having trouble finding a place where someone installed all of these at once. I'm wondering where I should start? I took of the old coil and put on the new one and I'm getting a little hung up on the wiring from the coil to the e-advancer. The coil has a blue wire and a blackandwhite wire the e-advancer has black red and green wires. Also I'm wondering what all I can get rid of in the process. Yes I have read the installation instructions on Yamahaxs650.com Thanks for the help in advance.
 
What do you mean by coil has blue and black/white wire? Pics will help. What are you wanting to get rid of?
 
benjammin,


The color code on the coil wires is from Honda.

The polarity of the coil doesn't really matter, but just for conventions sake, connect the coil black / white wire and the red wire from the E-Advancer together to to the red / white wire from the kill switch. That just leaves you with the green wire from the E-Advanacer and the blue wire from the coil, so connect those two together. The black wire from the E-Advancer goes to frame ground. Be sure to lovcate the E-Advancer far from the coil, like under the left side air filter cover or under the seat. Tie wrapping it to the wire bundle under the left side air filter cover works as the wire bundle works as a shock absorber.

Exactly what I was looking for thanks Pete. Looking forward to seeing how my bike runs with this new setup.
 
Pete, how many advanced locating pins are used in this process? I got three in the kit.

You may have some extras because the advance rod typically comes with its two pins already installed on either end, in which case there is just the third pin that is installed in the cam shaft on the advancer side that engages the slot in the advancer replacement cap.
 
Thanks Pete, I figured as much there were a few extras on the rod. Just making sure I did everything right before I started her up, and having extra parts made me a little worried.
 
Something is definitely not right. I got everything in and temporarily wired up so I could start it. It acts like it wants to start every kick but won't. Then after about ten kicks I can get it started but not for long, dies after about 10-15 seconds. Any ideas?
 
I got it running with half choke. Then i adjusted the idle and it seems to be running great. Is this normal after installing a pamco? Just wondering. Probably something else I have to fix. :doh:

If you mean, it needs to have the choke half on to keep running, that indicates that the pilot circuit is not delivering enough fuel/air. The pilot jets themselves may be partially blocked, and/or the mixture screw may be adjusted wrong.

Have the carbs been taken apart and cleaned properly? Have you read the Carb Guide and confirmed your carbs are adjusted as per the spec table in the Carb Guide?
 
Figure8 yes I timed it. Retiredgentleman, I cleaned the carbs while I was waiting for the pamco. I also added fuel system cleaner which may have been part of the problem because after I rode it a while it went away. Now that I've put some miles on the new ignition the old lady is running better than she has since I bought her 4 years ago. The only weird thing that is happening is the engine will speed up a little bit when idling. I haven't figured out a pattern or anything yet, but when I'm sitting at a red light or stop sign it will jump rpms slightly for a couple seconds and then go back to normal. It never did that before the pamco.
 
benjammin,

There are generally two causes of what is known as "idle hover", such as what you are experiencing. Either the mechanical advance springs are too loose and the advance is advancing too much for the idle speed thus causing the idle to increase or the carbs need to be synced.

The PAMCO E-Advancer is not capable of providing an advance that does not match the engine speed, so that just leaves the carbs, which you also worked on at the time you installed the PAMCO, so the question is, did you sync the carbs?
 
A lean condition can also cause a hanging idle. Check your jetting and check for vacuum leaks. And, of course, the obvious...such as cable routing or binding /sticking throttle cable.
 
Hello Benjammin, thanks for this thread. I am installing the same pamco, with e-advance. Is there any wild chance you have any photos of the wiring connections? I'd be in your debt! Thanks

Yes!!!
You need a kill switch. Leaving the key on for even 30 seconds can fry an ignition. The kill switch lets you check lights and other electrical components for power without damaging the ignition. Its the easiest thing to install, yet so many go without one. Not good.
