well, I installed the dyna because i kept having problems with my points in the winter.....turns out that could have been an unrelated electrical issue. I have had to have my dyna warranted once in the 7 years i have had it. I would like more info on the Pamco as I have looked at it as a possible replacement if the dyna fails again. I am 1 of those who prefer the simplicity of the electronic ignition merely because I hate setting points, altho I can set them.

Pete, do you run the show at cb750 supply? I see that there is an ignition coil available, OEM Ref. #30501/30502-300-003/013 that is $35, but is listed for cb750s. think it would draw too much for my 550 if I stick with the points setup?

I just bought my 73 CB500 Four this past week...and I was thinking that an electronic ignition would be one of the first things to replace before I get it running. Do you you guys recommend doing this as one of the first things to upgrade on a new build? Or should I invest in something else before I dive in to the ignition? Thanks in advance

Well, I think that when people say that an optical sensor is better than a Hall effect sensor, they may be misinformed. As an example, the factory ignition on the DOHC CB750 is often refereed to as a Hall effect ignition, but it is not. It uses a coil pickup to trigger the spark.
Pete,
I trust your product based on its track record, but I have a question. On the units that use two Hall effect sensors, is at least one of them adjustable? I ask, because I'd prefer to have both coils firing right on the mark rather than using a split-timing technique and having to settle for "close enough" - one coil firing slightly advanced, the other slightly retarded.

Stu

Stu,

The two hall effect sensors are set up to fire at the same relative position during the final testing by matching the Hall effect sensors.

That coil has 4.5 Ohms of primary resistance, so it will work fine with points and not draw any more current than your stock coils. If you decide later to go with a PAMCO, then you can continue to use this coil. It does not produce the same high output as the 17-6903 "Ultimate" coil, but it is a good everyday rider coil that runs cool.

PamcoPete.....................is it possible to fit this ignition into a 81 suzuki gs1100e? I only ask because the Dyna is available for this bike....and I have had my 750F dyna plate mounted in the suzuki engine to see if it fit.......so presumably your ignition would also fit? thanks for any info.

Well, if you could post a picture of the stock ignition and the ignition rotor, I could have a look.

Sold! Ive got my coils gutted, ready to solder new wires in, but before I waste a bunch of epoxy, I'm just gonna buy a set of those coils. Thanks alot.

I bought the Pamco electronic ignition and "standard coils" from CB750 Supply for my '77 CB550K. I couldn't figure out how the coils mounted however. (couldn't use the stock mounting brackets, and the holes on the frame didn't seem to line up). I'd appreciate any tips if anyone has installed the coils on a 550.

pamcopete · « **Reply #35 on:** April 16, 2011, 04:49:45 AM »

Tree,

Could you post a picture of the stock coils in place?

Tree · « **Reply #36 on:** April 16, 2011, 09:13:21 AM »

Pete,
Here are pictures of the stock coils as installed ('77 CB550K), one from the left side and one from the right top. Also included is a picture of the new coils received as part of the kit from CB750 Supply.

You will note that the stock coils mount to a bracket on each end (vertical screw), and then these brackets mount to the frame,( horizontal screws). This holes in the frame are about 4 inches apart. Side by Side mounting points on the bracket are about 2 inches apart. If I orient the new coils as shown in the picture of them, then I can fit them side by side in the stock brackets, but I have a slight clearance issue with the bracket and blade electrical connectors on the coil. I could probably eliminate the clearance issue with a 1/8 to 1/4" standoff between the coil and bracket. This would require a slightly longer than stock screw to accommodate the standoff. Finally I'll note that the blue wire on the new coil has a male bullet connector. The stock coil has a female connector, so a connector change or adapter is required. (The black wire is consistent with the stock wire).

Appreciate any guidance.

Some thoughts...

These are both "hall effect" and probably work very similarly. The Pamco in theory, works with 2.5 to 4.5 ohm coils. The Dyna works with 3 to 5 ohm coils (needs verification). Many on this forum would recommend 5 ohm coils.

Will the Pamco unit work with my 5 ohm Dyna coils?

HMM I am interested with this as well.

dave500 · « **Reply #39 on:** June 26, 2012, 10:17:28 PM »

you can use the stock coils which are 5ohm aswell,make sure the caps are to resistance spec,5kohm.

OK, but what about the Dyna 5 ohm colis that I asked about?

dave500 · « **Reply #41 on:** June 26, 2012, 10:28:06 PM »

they are 5ohms also,previous post edited.

not sure which points your talking about, but the Honda ones (the only ones worth using) cost $25 a piece. Throw in another 10-20 for more condensers and a pamco starts to have a bit more appeal. .. and for what its worth I am still using stock Honda points, ..to each their own.

PeWe · « **Reply #43 on:** June 27, 2012, 02:21:16 AM »

Stock Honda points can fail too.
I replaced the complete ignition plate just before a holiday on wheels. One contact breaker did not last long, appr 3000km. It failed on French highway and I had to drive on 2 cylinders about 50km to get a new part.
So, it does not matter which ignition system you choose, it might fail anyway. Maybe possible to attach a complete OEM plate somewhere on the bike as spare.

I'll probably go for a Pamco. But I do not know if the Pamco ultimate is the best choice. It's much cheaper to buy it all from the very beginning when it cost more to add the coils to a basic system afterwards.

Anyone that has compared Pamco basic with ultimate?

Deltarider · « **Reply #44 on:** June 27, 2012, 03:49:30 AM »

Are you sure that's a genuine Honda breaker point? All the stock one's I've seen have TEC stamped on them.

Terry in Australia · « **Reply #45 on:** June 27, 2012, 04:49:34 AM »

My favorite electronic ignition is the Martek 440. I've got several here, and the one that I had on my CB750F2 has outlived 2 previous CB750's. I bought a NOS Martek 440 for my Suzuki GS1000E a year or so ago, and with a new pair of Dyna 3K Ohm "green" coils installed, it'll start with a minimum of choke, and idles @ around 500 RPM from cold.

I just spotted this one and I'm sorely tempted to do the "Buy it now" thing, but to be honest, I've got more than I'll ever need now, so if someone here wants to buy a really good ignition for cheap, get this one. Hell, if you don't like it, you can sell it to me! Cheers, Terry.

I almost bought that, until I saw the shipping. give me a break. 33 bucks to put it in a 5 dollar usps box. wow.

As far as the pamco goes, I have one and have put about 800 miles on it. seems to work well. My only advise is to order it 2 weeks before you need it. It seems to take a while to get it.

raymond10078 · « **Reply #47 on:** June 27, 2012, 07:50:26 AM »

I just bought a pamco - and it was here in two/three business days.

I think that the delay may stem from whom you buy it. I see at least three sources (cb750supply; cb750ignition; and vintagecb750).

I bought from cb750ignition. I may have been lucky - or chose the one that keeps more in stock? If you need it quick, I'd call before I order.

That Martek electronic ignition is actually listed on Ebay.com.
Free shipping to lower 48 states with BIN.
Search it there.
