smoke coming out of ignition module?

[sgq700]

as i said, i have a vac adv unit but do not have the pick up's. if you want to change your's to a 1100 ign, send me your addr. and i'll send you the vac adv unit

Thank you, I'll pm my address...

 

[sgq700]

you may be able to use your 1200 pick up's in this unit?

Pm your address to me too and I'll send you the rear housing complete with a leaking vac advance.
Swap that with the good one.

I think I have a ballast resistor for your coils.
Post a picture of the coil pack.

No. The vacuum advance won't go on and there's no centrifugal advance on the 1200 housing.

the 1200 is locked timing eh? no wonder that control unit is a bugger :shock:

No it used vacuum advance off the intake to the 84cdi, and supposedly the cdi also gets signals about what gear you're in and adjusts timing accordingly, but not with this wiring harness.

What does the vacuum line from the new 1100 rear ignition housing plug into? With no cdi and single carb I don't understand what that vacuum advance would be connected to.

 

[slabghost]

Same place the cdi got it's vacuum from the line from the carbs.

I can't get a picture but these are the identical coils with the same numbers on them:

You mean off the intake? Oh ok, now I get it. It'll be a mechanical advance with the new setup rather than electronic.

 

[sgq700]

or on your carb, you have a vacume nipple for the vac adv to the dist.

I believe the vacuum from the carbs pull a lever on the timing to advance/retard the timing plate. It's much like a carb choke-pull-off from the same era. So it's a vacuum operated advance. The 1200's had a computer to control ignition timing using the gear information and the vacuum information. Doing this allowed the 1200 to be able to safely advance the timing to 45 degrees. The 1100 should work fine.

Then am I giving up much performance going to the mechanical advance, and if so how much and where? Low end torque will be the same i hope, top end is limited now by my carb anyway, but i have plans to upgrade to a 32dft i have.

I guess reliability is preferable to max performance, but I don't want to give up too much esp when I make the swap to the weber carb. And I still was looking into the neon coil upgrade also.

I don't need top performance but I figured since someone went to great lengths to build up this engine, I may as well try to take full advantage of his work.

As I said, I think the 1100 will do fine. The thing with yours is: you still don't what's there.

Ok yeah, that the stock 83 coil pack which uses a resistor.
I'll dig up what I have this weekend and post it.

 

[slabghost]

You won't be losing any performance using the 1100 ignition it uses both the mechanical advance and vacuum advance to get to full advance. As stated before the c5 will give you the best performance if you save your change long enough.

 

[joedrum]

coils of low reading from stock are the cookers ...coils above are not so damaging ..seems most of the car coils in up cooking the iggy parts ...

 

[83gl1200]

Ok so that confirmed a parts mismatch for sure right?
These 83 coils without a ballast resistor were just too much for the 84 cdi? I just want to make sure, so that I can look into running neon coils with a ballast resisitor.

Maybe one day I will be able to upgrade to the c5 ignition but until then, neon coils will have to do.

I didn't see any cracks in these coils and I guess they test ok and would probably work fine with a ballast resistor added back into the mix, but being over 30 years old it's probably well past time to replace them anyway.

 

[joedrum]

yes i think so ... i would now pm blacklander to help you isolate the 1200 ignition set up .. and try to hook up iggy sydtem totally seperate from honda wiring ... maybe backlander has good set of 1200 coils ... but for sure if you want to used the new ebay box you bought backlander is the man here to help you get going ..and this is probably the cheapest route as i see it ...blacklander knows 1200 parts and has several bikes to look at and tons of 1200 info in mind and manuals .....

As said above, I'm not an electrical expert, but I would find out what resistance stock coils were and ad a different resistor to make up for how much lower the Neon coils are. I'll see if I can find it. You probably need about a 2.5 ohm resistor to bring the total up to three ohms. Maybe I have it backwards, but I thought lower resistance in the coils can end up allowing to much through the ignition modules. Coils will have the same time to saturate but less resistance in the coils?? I could start a new thread, cause I'm asking, not telling. Anyone? Toehead probably knows.
