Dyna Coil Installed - Crack-O-Matic Toast

[beemer]

Pretty simple install, really. Had to take a cut-off wheel to an overhead and empty wiring plug attach point so the new coil would fit comfortably, but that was no biggie. The Motorrad Elektrik aluminum coil bracket is the essence of simplicity and function.

New coil, wires, caps and plugs. My cow is getting happy. Got some more cleaning to do. Hello, Simple Green.



Dated the coil install with a Sharpie in case I forget.




... and the original coil. The circular pattern of cracks were hidden by the snake's nest of wiring.

I'm thinking of replacing my original coi,over here in the UK they sell a Bosch replacement,would you say the one you have just installed is better?does it have a bigger output,hence bigger spark?i can't seem to find anyone in the UK who sells these so i would have to import it,give me your opinion before i make up my mind which one to buy,thanks.

I went with the general BMW owner consensus that the OEM Bosch coil is not the most reliable over the long haul. Mine cracked just like the forum folks described.

The Dyna coil is also about $30.00US cheaper than the BMW replacement part. That may not be worth a squat in the UK! Rick Jones and his MotorradElektrik lash up are great to work with. Quick service and honest.

Do not know if it puts out a hotter spark. Don't really care. But I do know that my R65 starts and runs so much smoother than it did before. I'm sold on the Dyna coil. It is a very easy and quick install. But an OEM Bosch would be too.

Ultimately, it'll be your call. Have you Googled up Dyna coil? May find something in the UK. [smiley=thumbsup.gif]

Most wiring diagrams indicate a "special equipment connector" as part of the harness - an unused socket. It has battery power, ground, high and low beam, and ignition power going to it. I assume it could be a good place to plug in accessories or to trouble shoot part of the electrical system. Although I don't know where you would get the matching plug.

BMW does not recommend using a sidecar with the R65 so it is not meant for that although it could be used.

I did google dyna coils and came up with a company here that can supply them,7 to 14 days delivery,BUT,the model you have costs £150,which converted to USD is approx $292,so,far too much shackles for me!!anyway,the outcome is that a BMW specialist company over here in the UK suggested i use a coil from another BMW model that will work and last,so that's what iv'e done,the only drawback is that you have to make a mounting bracket,that's not a problem for me,so i designed and made one to hold the coil,it works and i'm pleased with the result,so all's well that ends well as the saying goes. 8-)

Wow, they must slap a really HUGE VAT on imported coils for making it 150 pounds, even with our weak dollar on the exchange !

Yes!you have import duty and also VAT @ 17.5 so it bumps it up,you don't seem to get away with anything nowdays!.

That's ridiculous, the bare coil here is just a bit over $60.  But, I suppose it keeps local manufacturers happy.  I wonder if that is what has kept Lucas alive all these years?

Is it "profit" for the seller or "profit" for the government in the form of import duties?  If the customs isn't too bad maybe order from here, $130 USD for a pair?  I ordered a pair and made my own mounting brackets:

I think that it is a primary source of revenue for the government over there.   They need all the money to pay for more
cameras with which to watch their population, after all..

I work with an Irish fellow who spent much time in England working on electronics communications and printing equipment.
Depending on how the equipment was classified, there were VAT or import tariffs ranging from about 8% to as high as 80%,
I think.    Well, I guess that our country has similar sorts of tariffs on ethyl alcohol and other things to help prop up our local
growers/suppliers, too.   If the British government can do this for Lucas et al, I am sure that our government would do the
same for our local manufacturers, like Harley-Davidson. Oh wait, they already did that..........

I wonder if I could get a job watching the monitors those cameras are hooked up to, when this job runs out?

I ordered a Dyna coil from young Rick a couple of years ago as the price for them in England was ridiculous. I think you had to buy a pair too!
It arrived after several weeks delay as those b***ds   at UK customs slapped import duty + 17.5% VAT on it and I had to pay the Post Office a "Handling Fee". It was still significantly cheaper than buying it over here.
A cheaper way may be to pay someone to obtain one in the US and post it to the UK as a "personal gift".
You may get away with it as they seem to look for parcels from companies first!

As an aside I had to order a green one for my Boyer electronic ignition. Both are magnificent and have transformed the old girl as I'm sure all the old ignition components were very, very  tired.
Starts easily in all temperatures and I lost the BIG flat spot at 5,000 revs.

Help!  Help!  Help!  While dealing with the float bowl overflow issue of my 1983 R65 - riding along at 45mph - engine cut out,  tach needle stuck at 4000rpm - with dead engine.  Coasted to stop, carb NOT overflowing.  Tach needle casually returned to 0.  Waited a few minutes, pressed starter, engine spun, coughed, started right up.  What the?  Rode short distance home engine running smooth and even.  Inspected under gas tank, observed nice long crack in original grey coil both plug wires attach to.  Ordered new coil from BMW dealer, gave year of R65, described coil needed.  Received single 6 volt cylindrical coil from dealer.  What the??  Checked parts schematic online, only coil shown is coil as sent, nothing like what is on my bike.  What the???  Is original coil available or was Dyna Coil used as original no longer available?  Do engine cut out symptoms above indicate specific electrical issue?  Would cracked coil produce symptom?  Anyone out there have similar experience?  Bike is forlorn sitting in garage...

Original Crack-Os should still be available. They'll cost you more than the nice Dyna unit and everytime you ride, you'll get to wonder when it's going to crack again. Yes, a bad coil can create the problems yo u described.

Send it back! Get an order off to Rick Jones at Motoradd. $90 bucks and a ten-minute install job.

DgM, the 1979 and 1980 models used a pair of the round coils and all later bikes used the dual coil.  If this dealer sold you one round coil for a later bike than that tells you volumes about their competence regarding the older bikes and they should probably be avoided like the plague.  The Brown Dyna coil is very popular on most Airheads over here because it is a superior coil to the Bosch and only costs about 1/2 as much.
