Dyna S alternative - GM HEI on a former points ign. bike?

[Chuck78]

After shelling out a ton of cash for two Dyna S ignition pickup/modules in two years for the same bike (Dyna 1-4 pickup died on the 77 GS550 just out of warranty), I am looking to probably upgrade the points on my GS750 to the GM HEI ignition module mod.

What I was wondering, whether or not the early 80's models that switched over to electronic ignition would swap the ignition pickup parts directly into a points engine? And if so, do they still use a mechanical advancer similar to the points setup? I am looking for the most reliable electronic ignition setup and a better spark, with less maintenance than points. What factory parts are the best bet for me to look for?

Is there a big advantage to go with a different set of coils at this time as well?

Pete has a great product and has been making these systems for the Ymaha 650 twin for years. 5 year warranty and works with stock coils. $115 shipped. http://www.gsignition.com/

I use ACCEL and nothing else- Dyna just doesn't last for me-

I think I have seen reports of using the '80 or '81 pickuips on earlier bikes. They still use the same mechanical advance unit. I don't remember if it was '82 or '83 when they started putting the advance into the ignitor. You could probably search the parts fiche on '82 and ''83 bikes to see whether they compare to the '81s.

My 82 G had the advance incorporated into the igniter.

how would you use the accel on our bikes

I think he's talking coils.

I believe the ignition signal generator plate is a direct swap on the 550 and 1000, not sure about the 750 but suspect that one as well. You need to get the type intended for use with a mechanical advance - as Dale suggests, some of the later GS bikes went to incorporating the advance curve into the ignitor.

thats what i thought, figured i would ask

I was pleasantly surprised to find Accel coils on two of the bikes that I have gotten.

Yep- ACCEL gives me perfect fire. That equals a perfect ride
I was speaking of the coils- Dyna brand just not reliable in my use.

So this works well with the Dyna and Accel 3.0 Ohm coils I assume ??

[rwcfrank]

Thats my understanding.

I have had no problems with Dynatek's products & their customer service is second to NONE!!!

After only a year and having some misfiring issues, the 1-4 pickup on my wife's Dyna-S just died. I read online a lot of other people who have had the same problem, but have also read of other people who say they are dead reliable.

I wanted to go with the GM HEI mod because it makes sense that putting the ignition's electronic controls components inside the engine would obviously get really hot, so no wonder the Dyna stuff craps out on some people. Having the electronics mounted outside of the engine on a heat sink plate makes way more sense to me.

I also noticed a trend of more people complaining about the 1-4 pickup on the Dyna dropping out, and I speculate that this may be due to the fact that the front of the engine there gets more direct cool airflow than the back. maybe I'm going out on a limb there since they are both in a sealed compartment together.
