Dyna Coil Mount

swooshdave · May 19, 2010

Sadly for all of you I got a couple parts shipments. That means a flood of posts from me. You have been warned. :mrgreen:

First. Dyna Coil mounting.

I'm really leaning to some thing like this CNW setup.

Old Britts mounts theirs like this.

The biggest difference I can see is that it looks like CNW solid mounts the coil and Old Britts rubber mounts theirs. Is this a concern with these modern coils. I mean, they use them on Harleys... :roll:

Anyone have pics of their coil mounts?

First way tucks coil up neat under tank and its about shock proof
plus dear Sir this is Commandos were into, so chassis
and what ever it carries is isolated from damaging vibration.

First way is how I just did Peel but by epoxy two blocks of
Al as gussets - frame to tank mount plate - but with studs
sticking out so coil slips on and stays till I nut her up.
But Peel tank is moved back 3/4" so may not work on yours.

I figure the most solid mass attached to frame the more
its inertia resists transmitting nuance engine oscillation and
road texture and wind buffet.

Don't you want the coil in the air flow? The plug wires look so perfect. :mrgreen:

I solid mounted my Accel Epoxy Coil on my Shovelhead. Never had a problem with vibration. It was solid mounted originally too.

Dave,
If you like how it looks, hook it up!

I am behind the curve on coils I guess, still trying to figure out what to do about so many other issues. Did you compare the Dyna coil to the CNW coil? Anything other than cost? Assume you are going EI...Tri-spark?

Dyna coil was about $80 from Old Britts. PVL coils that can replace the stock ones are about $40 each. So it's a wash, except with the Dyna you don't need the resistor or other crap. Fewer things to go wrong.

And I'll be using a Boyer.

My further thoughts on 1st mount is,
gives nicer routing of plug leads, I like them to come out
of nowhere to appear wrapping around from rear loop to plugs.

These coils arn't hardly working hard on 7000 rpm twins,
so if lolly gagging or idling, they ain't got much watts to
radiate, while going with purpose give turbulent air assist.

But my main reason is vanity for least clutter blocking the view
though the Commando's profile.

I'd like to get boots to cover the raw trigger terminals,
must be some Harley or air craft or marine, lawnmower item
to suit so On the hunt.

I like that idea. Please share if you find something.

swooshdave · May 21, 2010

Do you think the cardboard will be strong enough? :mrgreen:

But seriously the coil sit right in there like it was meant to be. And the plug wires just love it too.

Any suggestions on how to fab it for real?

Swooshdave,

Coil wires are inanimate objects. They are not capable of love. Is the bike talking to you?

Walk away from the bike. Hug you wife and that adorable kid.

Remember, when you talk to your bike, it should remain silent (except the exhaust).

You would have to paint 'em to match unless the red worked into the scheme. You can also buy cans of liquid rubber stuff for dipping tool handles and make your own.

That would be 3 brackets ( 1 welded , 2 bolted ) + 10 bolts to hold up 1 coil .
Surely there must be a simpler way ?
Why not remove the original coil bracket and weld a tab on the tank support bracket ?

Dammit, I think you're right. Well, 2 brackets, the other one that's welded on is to hold the tank. :mrgreen:

But I was going to use the side of the bracket to hold the turnsignals...

Lets throw in one more

That's pretty cool.

pete.v · May 21, 2010

That must be the other good place for overkill.

I'm thinking maybe duct tape, wire ties...oh...I know .....BUNGEE CORD.

"L" shaped plate, 2 holes on the front face for the coil, 1 or 2 holes either side of the top face to bolt to the existing 4 holes for OEM coil mount using either 2 or 4 bolts, depending on how long you want to wait between having to replace lost hardware. Top face wuold have to have a cut-out to accommodate OEM flanges on tank mount uprights.

Done.

That's the Old Britts method. I don't like the idea of mounting the coil so that it levers the mounting system.

This is most likely. It's within my skillset. :mrgreen:

Swoohdave,
I feel your infection, just feel sorry for those that don't
have a first name relationship with their Commando.

I like your HT leads nice snaking to the plugs.
I'd love to see your cardboard in polished highlighted
hard wood grain, eh?

Be CAUTIOUS of removing Any support to the tank mount plate
and adding loads on it, DAMhik. Check it close Now.
Without an under plate stiffener it will crack right off.

Would be tricky to weld tabs on robustly enough to
hang coil on and not vibrate a fracture eventually.

Might try sticking a raw stud along the frame tube or
under the tank plate to see where it projects to
locate coil, May have to make gusset blocks to
epoxy-weld to hold the studs.
Then it'd be only a 2 nut coil mount.
