Hey, this isn't a good way to preserve interest in airheads. I look to you guys for info and knowledge, but when you start slinging shit like a bunch of monkeys, I loose interest. This thread had a question at the begining...SS did you even get an answer or an opinion? Grow up you guys, and teach us something besides the fact that everyone has an ego. I already knew that.

You give this thread too much credit. It's just the internet. Airheads are Euro Harleys and aren't going anywhere.

You guy's? I am not suggesting you stick things up your ass or any number of other rude suggestions from DT. I ignored it long enough and nobody said anything except for fishkens. ag, and WW. After all his name calling to boot I come back with a few myself and now it is "you guys"? I won't be swift boated. That's why I respond to that crap. I have wined numerous times about his behavior with no response so I fight crap with crap. DT has been on my back in a personal matter for a while now. I am not going to set there while he goes on and on and on with rude, personal comments. I have talked bikes with it no problem and have done so in the past but . . . . Here we are.

Dyna emailed me again and really didn't answer my question specifically but did say that I was right in that there is no difference between the coils and that he wished Dyna would stop selling the coils under two different PN's in order to avoid confusion.

Talking with a friend about it, he summed up my question in a very specific way. What is the secondary resistance? The primary is the same. The answer is in the secondary? Well, except for the insulation that WOULD answer my question! It seems to me like they are the same coil insulated well enough to handle 6 or 12 volts.

I'm 3000 miles from home right now and don't have time to babysit the butt hurt. Chill or I'll ban all of you until I get home to sort it all out.

I get less drama from my teenage niece.

Thanks.

I asked ME Rick a very similar question once because I wondered why 6V volkswagon coils were used on our 12 volt airheads. He said that there isn't a difference between 6 and 12V coils. FWIW

I asked him too and got the same response. I am going to run two 12 volt .7 ohm coils in series with my electronic bean can. Oh the horror!

I always thought "how does the coil know what voltage it is getting" but I thought it wouldn't hurt to ask around.

There is little difficulty in proving for your self if there is or is not a difference. Just install a 6v coil on a 12v VW aircooled bug motor. Compare spark at the gap for both. You tell us, same/better/worse.

If it starts, run it for a while. Does any smoke leak out of anything??

I have never done this so I don't know. What I do know from experience is stock works great, always, for intended purposes for which it was designed. Certainly with regard to Airheads. I also know that dual plugging got very well sorted out in the 80's. Several quality suppliers can send you a matched set of parts along with heads done right. Step by step install for proven conversion, with a final rational process for dialing in the timing for your airhead. Simple, least cost procedure for proven results.

I have no issues whatever with others doing experiments with their machines. Or developing refinements for uses other than intended for stock purposes. Racing?? No way to be competitive without serious mods financed by your wallet. The only thing I have to do with racing is spectate.

Heavier wire is needed for 6 volt systems, and probably one of the reasons cars converted to 12V years ago. So it's possible the primary on a 6V coil is larger. But when you wire two six volt coils in series it adds up to 12V, so you're good.

Anybody have some junk coils we could experiment with?

As for the mud slinging - there's a good saying about that: When arguing with an idiot it's difficult for others to tell you apart.

Name calling recoils, no matter who started it, and leaves both parties muddied. So take the higher road, stick to the truth and be civilized. And don't be so damned defensive and thin skinned! This is the IDIOTNET, after all.

Frankly, I think it's pretty derrogatory calling the net that, since it's what brings us this wonderful forum and many other really great things.

I never waste time on idiots, easy to ignore. Different completely than charletans. They are cheats and liars, and need to be exposed as such. Just one opinion and I will fight for your right to disagree.

My take is that back when there were coils with a certain primary resistance used with the common 6V systems and coils with another primary resistance used with the newer 12V systems and, by custom, they call them "6V" and "12V" coils. The important factor is the resistance of the primary and my rule of thumb is "what did the factory coil run?". My /5 uses two "6V" coils in series with a total resistance of 3 Ohms in the stock system, so that is what I will use with the dual-plug-to-be system.

Remember, with a coil switched with either points, an ignition booster or an electronic ICU a critical property is the reactance and inductance of the coil in addition to the resistance. Almost voodoo.

Yes, all those who have proven the duel plug conversion do it that way. Just reprilicate the stock system with dual tower coils. If you have points, a booster just extends their life substantially, X5 magnitudes. Not necessary, but if you are now throwing 4 sparks instead of two, adding some robust enhancement here is good money spent.

For electronic, dead stock hall sensor and Ign Mod with the lower resistance dual towers.

Bought as a package from trusted Airhead vendors can't be beat for all road riding. The vendor will be expert in any help you need to set it up. Nothing pleases them more than your success. They simply don't discriminate between nOObs with Airheads and Airheads with Airheads.

Certainty of results is at hand for those who don't care for experiments under the shadetree with smokethewires results. Take the no risk solution or the more risk road as you will. It's ok, as long as lightening your wallet more than necessary is ok with you.

Costs nothing but time at the speed of light to have access to the archive of airheads.com. Takes time at the speed of your ability to absorb the data and opinions and questions and answers of whole bunches of nOObs with Airheads to thousands of Airheads with Airheads, and by God, the blessing of the opinions of the Gurus. Ignore them at your peril.

Learn by the mistakes of others and you don't have to make those mistakes if you don't want to, Because You Can.

It costs you nothing to sign up to the list, where you can submit any airhead question you wish to BILLIONS of use miles of Airheads, the nuts holding the handlebars of their Airheads.

Heavier wire? My question is about two "different voltage" coils with the same primary wind resistance so that rules out thicker wires.

Thanks for the name calling advise. I followed it with DT for quite some time with it only getting worse on his part. I hate to say so put it seems to have gotten much better since I hurled some crap back at him in kind. Ignoring it was certainly not helping DT change his ways.

Derogatory? We are all in this mess together. For years the biggest thing on the idiotnet was porn. Is that still the case? I am all for calling it for what it is good for. Sorry that offends you but I get offended all the time on it. I try not to bog the thing down with what I think of it unless it is motorcycle specific. If we all went on and on about each others annoying habits like some do, what a clustermuc it would be!

[QUOTE=supershaft;16141790]We are all in this mess together.

Agree we are all here, but there is no mess amonst Airheads. It is one of the most amazing 100% volunteer organizations I have ever seen. Just 2 or 3 Barley Therapy's and any nOOb with an Airhead can become an Airhead with an Airhead. On your own it will take you 3 years. Bring your Airhead with your parts for Duel Plug and BOOM, it's installed, tested, adjusted, confirmed. 2 beer job. YOU did it all under instruction of many who have done it right before.

If you go to an Airheads event and annouce you know more than Oak, expect to be ostricised.
