Topic: '76 CB550 spark plug cap resistance

[Deltarider]

Oddjob, you are creating mist. This is the internet. Anyone can present himself the way he likes. You can't blame me when I register when these folks that have sooo much experience, remain silent, when rubbish is presented by other members. I have ample examples of that. If these people don't even dare to ask questions to the person who presents rubbish, I start wondering why? Is it because they don't know better or don't they dare because they are not so sure? I don't mind to sanitize this forum every now and then. I do it by asking questions. Why don't you?

Now just to upset him, I have MANY years in the trade, he has none. Who would you rather believe? 

Well, not the one who has been in the trade sweeping the floor. Folks, there you have it. That's the level Oddjob needs to sink to anytime when he's asked for clarification. It's all about: "I'm higher than you in the pecking order and you, Delta shut up!"

[Deltarider]

Trolls believe what they want and arguing with a troll is like arguing with a fool, they will beat you with their experience arguing, not with their experience

Is that all you have to contribute? Really? Nothing better than that?

[Oddjob]

I'll ask a question then.

Delta why don't you just leave and give us all a rest? How's that?

Because he has no life other than to be argumentative, insult others, espouse his formidable knowledge of searching the internet and raving about his bike of 30 years is a unicorn. Honestly, if he has such disdain for the content and contributions on this forum, why doesn’t he just bugger off? Because he can’t. He’s obsessed with conflict.

It’s a lonely life for an internet troll…

[Deltarider]

Arguments, gentlemen, arguments... you can convince us with arguments. And when you don't have them, you can always ask, if you dare... 

[RAFster122s]

Apologies to Denward for having to endure the troll, hope you are successful getting new caps at a reasonable price and they last a good long time...

[Little_Phil]

It is surprising that this is never resolved fully, just like the function of the pilot air screw in the carbs. Maybe someone will provide proof one day but until then let it rest.
BTW: Great resto denward

[rotortiller]

This is just a thought on plug caps, I would reason a marginal plug cap would provide better performance at idle when the coils charge the most and if it were a problem due to high resistor values it should show up at upper rpms. Caps in the rain usually show their real short coming. I replaced plug caps way out of spec in the past but did not notice any real difference. I also found the resistors in the plugs can like the caps can drift off spec over extended periods, which does not surprise me considering the way they are held in with a spring affair. Want to see RF noise, park next to one of my H2 Triples with CDI and non resistor plugs and caps lol, it can feed through intercom bluetooth frequencies.

Delta has already wound up oddjob enough to get him suspended from uk forum and i personaly have given up reading and commenting on his posts

[Oddjob]

He’ll be posting on the UK forum how I’ve bullied him on this one next.

I don’t blame him, like I don’t blame other idiots from being idiots, he can’t help himself I’m afraid.

I often wonder why he feels the need to post on countries which are not his native language but I suppose they’ve had enough of his drivel and banned him.

[Deltarider]

Guys, it's obvious for anyone to see: they who have run out of arguments, what can they do? Well, call the opponent a troll. I myself never had to go that low. Go ahead, call me a troll, but I'm no chicken. When somebody posts rubbish, he should be corrected for the hygiene of this forum, no matter who the OP is. We all bear responsibility for this. However, it's my observation this correcting is done very selectively... IMO an unhealthy situation.
It goes without saying that your arguments are nevertheless welcome. As always.

He reminds me of the parable: When you’re dead, you’re dead; it’s only hard on those around you. Kind of like when you’re stupid.

We should all be so grateful that the omniscient One has graced us with His universal truths. And that He alone is obligated to correct the mythology to which He does not agree. Regardless of what country or which peasant dare pontificate…

From the textbook "Electronic Communication" by Robert L. Shrader, third edition, copyright 1975:
"In motor vehicles the major source of noise is the ignition system. The popping noise developed by the spark plugs increases in frequency with increased engine speed. It can usually be decreased by using resistor spark plugs and resistor ignition cables.."
The only purpose for resistance in the secondary of the ignition system is to reduce radio frequency interference, especially on AM radio. Resistor spark plug wires have been standard equipment on cars for decades, even before emissions became a concern, as cars only came with AM radios, and no one wanted a car with a radio that played static pops whenever the engine was running.    

[dave500]

ive had older used caps with high resistance,some you can unscrew inside and the resistor can be removed,ive cleaned a few and reassembled and all good.

[scottly]

The resistor is there to suppress noise, period. We do not know what rules the various markets had. IMO too much weight is attributed to whether caps had: 5, 7 or 10kOhm resistance.

This is correct. Also, regarding the variances in resistance, consider an auto engine with resistance suppression wires, where the resistance is related to the length of each wire, as in K-ohms per foot. On a typical V-8, the wires can vary in length, and resistance, by two feet or more.
Note: This is the only time I have ever agreed with Delta.  

[Deltarider]

From my side I have no problem in admitting that I have agreed with Scottly more often than not, especially when he had the courage to correct the 'experts', when needed. In doing so he was and is one of the very few who does not evade his responsibity. Very few indeed. As a matter of fact, I can count them on the fingers of one hand... and some were so timid in doing it that the image imposed itself they were wearing velvet gloves...
This indicates an unhealthy situation in our forum that I will not hesitate to address: not by calling someone names, but by asking and doing research, like I have done before. For some here this is already mere blasphemy. I can't help that.
If the signs don't deceive me, I already see the next debate coming. I foresee it will be about another invisble 'mystery' of electricitry: the capacity of our condensers. As you know, Honda has specified them: 0,24µF +/- 10%. No doubt someone, in his desire to profile himself as an expert will grab the opportunity to stress that the capacity is best at this or that end of the range. Yes, there's a difference: in theory the choice of the capacity is always a compromise. Has to do with the rpm range the bike lives in most of the time. The point is that in practice none of us will ever experience the difference. Don't get me wrong: there is a minor difference, but it is within the noise band. In science we say: the outcome is trivial. And exactly that has always been my position in the HT resistance debate.
But what great opportunity for some to profile themselves as expert. Please ralise that all these claims have one thing in common: when put to the test, the outcome will be within the noise band, meaning tests will prove nothing of any significance.
You can count on me that I will always try to address lies, half truths and 'alternative facts'. Basically they are all falsehoods. Why others prefer to blindly follow the leader, I don't know. You'd better ask them. Cadaver disciplin is the word that emerges in me, a concept we know since WW1. Some feel very comfortable in that attitude which makes them ideal material for the military. I wish you all a pleasant day.

[Oddjob]

For the sake of society I really hope Deltarider has a low sperm count.

[Stev-o]

Wow....is this to become the new "oil thread"?

I much prefer reading about what the best oil is to use!

[bryanj]

Stop poking the bear!

[grcamna2]

Please,lets give this thread back to what denward17 originally intended;I imagine he's appalled by this present dialogue  I think he may want to do what's best recommended to have his 550 run the best it can.

[Deltarider]

Although the rest of my arguments still stand, I have, much to my regret, perpetuated a fallacy in reply #35. Someone has rightly communicated me that the CB650 did NOT have a CDI, but a common transistorized ignition.
Unfortunately I have ignored the soft ringing alarm in my mind when I wrote reply #35 in the heat of the debate. I should have listened and have doublechecked, even more as you cannot always count on what the 'experts' here state. I now had a quick glance at the wiring scheme in the CB650 manual as found in this site. The first surprise was that I couldn't find the thyristor, which usually characterizes a CDI. The irony is that, what we see in that scheme is the same ignition I have made myself, be it Honda uses three individual transistors, where my ignition has one triple diffused Darlington to do the power work. For the rest they are identical. Ofcourse the CB650 had an electronic pulse generator, where I deliberately have chosen for the OEM breakerpoints to switch the control current. Another sign ofcourse is that the CB650 still has conventional 2-3Ω coils, where in a CDI scheme we usually see 0,2Ω.
I have never felt comfortable with the often read qualification 'CDI' for the CB650 ignition. It was a gut feeling: I have always judged it un-Honda like for their roadgoing bikes. Tipster informed me that as far as he knew, Honda had only fit CDI's on the early CX500 and some 400 twins as far as their roadbikes.
I apologise for the error made. I should have known better; after all the transistorized ignition on the CB650 is identical to what the GL1100D Interstate had, I once owned. I have re-edited #35 by adding: please also read reply #71.
