Re: PowerArc Anomaly
Well, I would love to be able to afford one. Mags have shown to be awesome. Ya know, that what used to be on all of them some time ago, I think.
From what I have read, the down side is that too hot of a spark can burn the top of the piston at prolonged periods of high rpm running.

Re: PowerArc Anomaly
Maybe YOU could offer YOUR experience pertaining to this, rather than usual open ended ANTAGONISTIC post. :roll:
Better yet, PM Dkt26 with your crap, it's his inquiry. I really don't care what YOU have to say. No offence, Dkt26.
No bill, I CANNOT. For street usage a magneto may be just fine and this seems to be the consensus. I would rather not believe it myself because I want one someday. The gentleman was coming from a competition point of view if I recall. I hope more will chime in on this.bill said:

Re: PowerArc Anomaly
The only way a magneto could melt pistons would be if the timing slipped, this might be more likely with a magneto.
Most classic racers use modern electronic ignitions, often housed in magneto bodies. I magneto is only as good as its last rebuild and the skills to do this properly are scarce and expensive

Re: PowerArc Anomaly
when this kind of tripe is posted that is what makes the key board commandos a poor source of information and when posted enough SOME take it as gospel.
If you cannot explain something than why would post about it. once again it looks like
" I read it on the internet so it must be true"
the older stuff was lucky to produce 10-12KV. the results of these weak ign systems was short plug life, low mileage tune ups as most would not make 12,000 miles and harder cold starts.
the new cars can be as high as 40-50 KV and you should know the results of this but I will spell it out for you. the new cars run over 100,000 with out a tune up and easier cold starting. also guess what, they don't melt pistons.
just maybe you should use you 2 ears more than you have been.

Re: PowerArc Anomaly
Yeah they are expensive for sure but gee I'm keen to try one.
I can get a brand new ARD but the maker is 83 years old so as time is inevitable, along with death and taxes, I fear that once the individual passes on from this mortal coli, so will the serviceability of the ARD. Hence the hunt setup.
I was a bit concerned about the straight ignition (no curve) but have subsequently read up about this and am less concerned.
Cheers

Re: PowerArc Anomaly
I think they stopped offering ARDs quite a while ago.

Re: PowerArc Anomaly
Sorry to hear of your bad experience of the Power arc. But glad the Premier Amal's work well, I am keen to try some on a Daytona project. I have put nearly all the Premier goodies in my standard Amal's. They were new bodies, that must have been pre-Burlen. After similar trials and tribulations that you have experienced, including new intake valves etc. I found the Amal bodies were at fault, they leaked internally at the frost plug inside the float area, that makes up the idle circuit. But for what it is worth, I switched from Mk111 Boyer to Pazon Altair, I know it is easy to crow about your own choice etc. But I found this ignition, with proper percolating carbs give my engine almost fuel inject type running, idle from cold is great, hot idle is great and off idle is all good too. But what I noticed and like against the Boyer is the way the engine responds in a linear fashion, if you raise the revs above idle the engine doesn't leap and shake like it used to on the Boyer.
Oh and hot or cold, I am disapointed if she does not fire on the first hearty prod.
Cheers Richard

Re: PowerArc Anomaly
Powerarc goes into single fire mode at some rpm threshold, below that the 3 sparks can be skewed from the initial to the last, so they can be put to occur pretty close together but not eliminated. Eliminating the 3 sparks feature to burn about anything smoothly eliminates a major reason to use Powerarc that does not require a idle stablization up/dn curve in low rpm to have steady idle w/o misfires that can bother idle stability. The capacity of Powerarc to allow extreme engine CR's is mostly wasted on regular Commandos, so might not be able to tell how good it is over regular electro ignitions.

Re: PowerArc Anomaly
I've been running a Boyer and single Mik for about 10 years in my Mk111. One or two kicks always starts. Idles nice and pulls strongly. So why then did I decide to go with Power Arc in project bike? I guess because of what I had read on this forum and the belief that newer has to be better, right? I have yet to fire up the project, but now you guys have got me worried. I realize there is no product bashing going on here, just personal experience. I hope this thread continues so some sort of resolution can be found.

Re: PowerArc Anomaly
I'll just note then that I went from a Boyer to a Power Arc and have been pleased with the Power Arc. I don't put much store in the 'multi-spark' aspect of it though, it seems like marketing malarkey to me. All in all, I'm happy I installed it.

Re: PowerArc Anomaly
I have not experienced any of these attributes with the power arc. I hope a single spark program can bring some functionality or it could be a total loss.
I was going to sell mine but have pulled the sale for further investigation of these possibilities, otherwise I will throw it up for grabs in the hopes that someone will benefit from it.
The encouraging (and the frustrating) part is that this unit work for many people., or at least it appears to.
