Dyna Booster... yes or no?

Points in a can on my 79 RS. I have recently replaced them with a new set. The bike runs well. However, after reading a few posts with positive feedback on the booster I'm wondering if I should hand over $100 simply for a fatter spark. Are they really that good? Are there any cons to the pros? I have no experience in this area.

Probably not. I bought a Dyna Booster on a whim, but my '78 points cost ~$20.00/set and the booster was $80.00 shipped. The '79 model points have a VW equivalent which is less expensive and easier to find.

I don't think the spark is any better with the Dyna Boost, the gadget just extends the life of the points - provided the electronics don't die. But, don't let me dissuade you from wasting money on a motorcycle gadget.

I'm a big fan. Your points will last a lot longer.

If you're running single plugs, it may not be worth it. When I went to dual plugs, at first I just put on the dual outlet coils and ran it. I was getting 1000 miles out of a set of points, and then the were burnt enough to cause running problems. I went a few rounds of that and then got the booster. It didn't really make it run better than it did before with a fresh set of points, but now the business end of the points lasts indefinitely, the wear block is what goes now, after a LOT of miles.

I'm running a GM 4 pin ignition module on my R100S as a points booster.

As per this web site: http://home.comcast.net/~loudgpz/GPZ...ForPoints.html

I mounted the module and the inverter on a heat sink piece of aluminum on the rear glove box under the seat cowl. Got about 500mi. on the setup so far with no problem. With the switch of two wires and reconnecting the condenser it goes back to points only.

Cheers

Sorry to dredge up this old thread, but I hope someone can fill me in on Steve W's setup.

The GM module sounds like a great alternative to a Dyna Ignition Booster. I'd like to try it. First, I hope someone can answer a few questions for me:

1. Do I understand correctly that the GM 4 pin module does approximately the same thing as the Dyna Ignition Booster (reduce wear on the points, and make the spark stronger)?

2. Will it work on my 1976 R90/6? It has a totally stock electrical system, including the original dual coils, stock voltage regulator, stock points, etc.

3. Is this the same module that Steve used?:

http://www.ebay.com/itm/Wells-DR100-...576d65&vxp=mtr


It sounds too good to be true. Saves your points, boosts spark, and costs only $10? I was considering buying the Dyna Ignition Booster for $70, but if I can get the same thing (sort of) for only $10, I would be all over it.

That Wells R100 module linked from ebay looks like the right one to me. You do realize that a circuit must be constructed, right? It's not like you add the module and go. Here is the link again to the page with the circuit(s): http://home.comcast.net/~loudgpz/GPZ...ForPoints.html

I built the Velleman K2543 module in about an hour from their kit (http://www.vellemanusa.com/products/...=enu&id=350487). But, I haven't installed it since the Boyer Brandsen ignition seems to be doing fine. Also, I haven't resolved how to pot the Velleman kit circuit board.

Yes the Wells R100 is the same module and there are several other equivalents as well. It's a common module.

And yes it will work OK with your existing coils and wiring although I presume you've seen the few extra components needed to trigger these modules with points.

If I hadn't already built and installed the Vellerman kit (see my earlier post in this thread, in fact my very first post on the forum) I would have gone for one of these GM modules as spares should be very easy and cheap to come by.

Don't get too carried away about the benefits although it would be at least as good as the Dyna booster or any other for that matter. Yes it's an electronic ignition but the performance improvement is limited by the coils and most electronic ignitions, BMW's own included, get there improvement by using lower resistance coils to boost spark energy. In theory even with the existing coils, there is some improvement due to the cleaner faster switching particularly when cranking and at low revs. My experience seems to bear that out. All I can say is that assuming I don't stuff up on the choke setting, the bike starts instantly on the button every time.

If you think that there is no justification for the Dyna nodule costing 10 times as much you are absolutely correct and the GM\Wells modules are a very neat solution. There are several others modules that have been adapted for a points trigger but this is the neatest and cheapest and the one I'd use.

^That sounds like a great tip! I'm going to look into that for my Guzzi!

I'm in the process right now of ordering the Velleman Ignition Kit, K2543, it is a Booster to use with ignition points.



I found one place that has this for less than $21.00 but I don't know about shipping charges yet. I'll report back later what the final cost is.

I believe this kit is mentioned on Snowbum's site. If not there I've see some reports that it works. Certainly much cheaper than a DynaTek Booster.

The Velleman Ignition Kit requires assembly so it saves money. After shipping from Arcade Electronics I think my final cost was just under $30. Much cheaper than Dyna.

I should have this in a couple of days. No telling how long till I get off my butt and put it together.

I am a huge fan of these "gadgets"... had a humongeous one from the -70' on a 3 cyl Triumph and I never/ever checked the points nor changed them... the thing was starting 2 kicks after 3 months of no use. I am buying one for my SV Dnepr...Pazon is making a great one with a couple of diodes (one for ON and one for points opening), I'll surely go that way: http://www.pazon.com/ignition-system...ive-earth.html

If it runs fine stock, then why change it. You can throw some money at it if you want, but really, those old points bikes have been working just fine for over 30 years. Going electronic is nice, but points are pretty easy to install and don't cost all that much, compared to the amount of miles you get out of a set.

But the Booster keeps the points only it doesn't burn them up so fast. If the Booster fails the parts are still in place to revert to stock ignition. I see this as a plus. I think the timing is more stable and requires less maintenance. If you think the points as issued by BMW are enough then I guess you can't be convinced. No problem.

No Disston, It isn't that I can't be convinced, I just don't really see the need to add another piece of electrickery to the equation. I have never had any major issues with the stock points on a totally stock bike. I have had a set die out in the middle of nowhere, but as I always carried a spare set of points and condensor, not a big deal to change them out on the side of the road. And you know it is the points right away, as you don't have something else in the system that just might be the issue.

We all know that ignition trouble always happens at the worst possible times, usually when it is getting dark and either threatening to rain or already is a total downpour. I prefer to have things as simple as possible, which matches up to my simple mind.

Now if you are changing other things, and trying to get more performance, Then I can see it being a good idea, or even better going to full electronic. To me, it all comes down to the application.
