ignition

The locating pin on my advance rod is too tall for the pamco to slide into place. That, or the indexing slots on the pamco were cut too short. If the indexing pin is pressed further into the advance rod (I have not done this) it looks like the fit will be loose, resulting in some side to side...

Allrighty, either I'm a moron, or I screwed something up, or both... I've read like three different ways to set and adjust the timing, and for some reason, can't make heads or tails of any of it. So, I'll pose this as fill-in-the-blanks sort of questions if any of you gents can assist. These...

Now now, the manual is on its way, but like any good XS fan I can't help but get started on this thing. I have a 77 XS that is all finished (YESSSS) and so I went to see if this 83 was running points or if there was a PAMCO or somehting. I take off the cover and discover....nothing! Then I look...

I bought my xs with a pamco already installed and it didnt have the advance unit. it seemed to run fine, and i rode it for a few months with no advance. What does it do if i dont have one? its an 83...

This looks burned. That's probably what I smelled yesterday. How would this happen? This would explain no spark then?

I see that the green wire needs to go to the negative on the coil itself. The red wire needs to go to the positive on the coil. But does the black wire off of the coil need to to go to a frame ground? Wellll, if the black wire out of the 6822 coil is the ground too, then why cant the green and...

Any help is appreciated. I just got the new spring replacement set from MikesXS because I owuld hit the throttle and the advance would stay open. I figured that since the bike only has 5000 original miles that it must be because the part is just old and worn out, but now that I put brand...

I am building my first bobber. First build period actually. After years of just tinkering I decided over the winter to just dive in and go for it. I have a 77 XS650 that I found in a barn and now it is a pretty sweet bobber. I recently got it up and running but I have read that the PAMCO...

My ride is a 1976 Yamaha XS650C. I recently installed a Pamco, a new advance unit, new advance rod, new Iridium spark plugs and spark plug wires and the high output coil. I'm no mechanic, but I did the install myself in a methodical manner. The bike started up just fine :D, but I had to...

Friends, So I got everything adjusted on my bike (a recently purchased 78 special): carburetors cleaned, cam chain tension, valve clearances, timing, ... the usual. Slap on the carburetors and fire her up. She runs beautifully on the first kick [PO said it has been sitting for over a...

I have a 81 650H running a boyer blue box (Micro-Digital Ignition System - kit 00103), I bought this bike with the blue box, so I'm back tracking a bit here. The terminal between my spark plug wire and the Gill ignition coil has broken off (see photo below). Where can i order new copper...

Hi all, I must to adjust the ignition of my XS but I don't know how to make it My bike mounts a Boyer Micro-Mk III Unit as you can se in the first photo. I read I must to rotate the engine anticlockwise until the rotor mark lines up with the first mark on the left (Full advance). And then I...

Must have been a slow day. I set up the test rig to run the "Ultimate" coil (17-6903), an Autolite #63 spark plug and an Iridium spark plug in the test rig, powered by a 6 volt lantern battery. This to simulate a hard start condition with a low battery. YouTube Video The plug in the...

I have an 83 xs650 that I rewired and bobbed. Im almost done, but keep frying coils. I have checked everything that I can and the primary windings still check good, but the secondary windings check at 30k ohms. This is the second coil that ive done this too and don't know where the problem...

I am running the pamco ignition with mikesXS part number 17-6803 with a primary resistance of 2.7 ohms. i am getting very random & sporadic spark only, and never enough to get the bike running. when checking for spark, i am able to get a smaller plug to produce less of this sporadic spark...

My precious XS has failed to start. I havent rode it in about a month. It has been parked in my garage hooked to the battery Tender. Ran fine when parked! I have 12.8 volts at the coil, but no spark. 13.2 at the battery. Anyone know of trouble shooting procedures for the Boyer Branson...

I have been fighting with my bike to get it running properly. after having it die a couple miles from my house I found that charging system was not working properly. What is the minimum voltage the ignition will still work?? wondering if this is causing my problems instead of carb issues. I...

the Pamco electronic igntion calls out for a dual output coil similar to the MikesXS part #17-6810 or 17-6822. I have the 17-6822 and the 17-6803. I have been using the 17-6822 but am reinstalling a new Pamco and the 17-6803 will mount to my bike alot better than the 17-6822. my question...

some of you might be familiar with my story. i was riding with my new accell super coil on :bike: then i had one strong backfire and now i have no spark. i know i need a new coil and all but i was wondering just one thing. what happened during that backfire that killed my coil? :confused...
