I’m a new member who has been lurking awhile and learning a lot from others post. I wanted to make a post detailing my experience with the xs charge ignitions because it may help someone else.
The bike I’m currently working on came to me with a malfunctioning Pamco (previous owner had wired the unit incorrectly.) I didn’t have the original points/ points plate or I would have just installed them and been finished.
I ordered the red xs charge unit that uses the standard advance weight assembly and fired the bike up, it ran pretty well. Test rode around the block a few times and went back to the shop to do some checks before I took off for a longer ride.
When I went to restart the bike it wouldn’t fire, no spark. I checked all my wiring, rechecked the coil to make sure it checkout with the voltmeter and found no issues. I tried to start it again and it started up. I just assumed maybe I had a loose connection on the coil so I recrimped my spade connectors just to make myself feel better and took off for a ten mile ride where I had no issues.
The next morning I went to restart the bike and once again had no spark. I emailed mikes xs and the rep replied with some ohm readings I could check and when I responded with my readings they verified I had received a defective ignition unit.
The rep from mikes informed me this has been a common issue with the red units and they didn’t have anymore in stock but they could send me an electronic advance (blue) unit as a replacement. I didn’t like the idea of replacing even more mechanical parts (the advance weights) and relying on more electronics but at that point I figured I would give it a shot because as I stated I don’t have the original points or points plate.
They shipped the new unit out that same day (Monday) and I received it 4 days later. Very quick turn around for a replacement part. The customer service was great.
When received the new unit I removed my advance plate as described in the instructions and installed the replacement spacer provided with the kit, then installed the replacement ignition and rotor on the left side of the bike. started it and proceeded to set the timing. The bike ran great..... for about 30 seconds and died.
When I tried to restart the bike and I was getting multiple kickbacks and coughs from the carbs. Because of experience with other bikes I knew that was a timing issue. Upon further investigation I found that the rollpin on the right side of the cam ( the xs charge kit spacer that replace the advance weights keys into it and drives the advance rod) had fallen out.
No big deal... I put the rollpin back in with some locktite “bearing and sleeve retainer” to hold it in place so I won’t have to worry about it coming out again. the next morning I started the bike up again and reset the timing. It ran pretty well...... until I took the bike off the lift and put it on the kickstand.
During all of this the bike has been standing upright on a lift and as soon as I took it off the lift and leaned it over onto the kickstand it sputtered and died. I figured that was just a coincidence so I restarted it and leaned it over again and the same thing happened... cough cough sputter die.
I assumed I may have a float height issue and when I leaned the bike over it wasn’t getting enough or getting too much fuel so I pulled the carbs and double checked everything but that wasn’t the issue.
The issue turned out to be that the trigger rotor on the XSCharge unit (what would replace the points cam on a points setup) was shifting to the left on the advance rod when I would lean the bike over. Apparently it was shifting just far enough that it wouldn’t trigger the ignition.
As the bike was running I could set the bike on the kickstand If I held pressure on the advance rod and it would run fine. As soon as I let pressure off the rod the bike would die. The fix for that was to add another washer onto the end of the advance rod so it holds the trigger rotor snug and there’s no movement “in or out” on the advance rod.
These issues are easy to fix but the fact that they aren’t addressed in the instructions and the fact that these units seem to be fairly unreliable is why I wanted to post what I have encountered so far.
