Hi:
My original brown coils have a weak orange spark. I have 3 new Dynatek DC3-1 coils but, at first glance, they appear too big to fit the mounting plate between the frame. Do I need to buy minis, or can these be made to work?
 
I think you'll need minis (and they don't get good reviews) however I have minis (2) and the fit well, performance so far has been good. Was it 'Haggis' who mounted them (coils .. but not dynas) behind the carbs?

I searched, but found no posting for coils mounted elsewhere. If someone has photos of Dynatek DC3-1 coils mounted on an RGS or SFC triple, please respond. Thanks!
 
Hi guys. My post about replacing and re-siting coils was on my SF. It was towards the rear, but not as far back as behind the carbs. Not relevant to any 3C.
 
The coils in the picture are not DYNA DC3-1 coils. The DC3-1 are much bigger than this and won't fit a RGS. They are much eaiser to fit on earlier triples. Your best choice for a RGS are TEK KP03 coils off a Kawasaki 250 (and other models).

They fit the stock bracket perfectly - as if made for them.View attachment 58381

That is not the stock coil bracket and those red spade connectors are problems waiting to happen. The bracket does look to be nicely made though.

The stock bracket is a flat alloy frame to which the coils are bolted. Quite prone to cracking, simple fix is to use 2 of them, one atop the other.

When replacing the stock coils, primary resistance of the the replacements must be observed. Most modern "mini" coils have lower resistance than the originals,they can fry the ignition system pretty quickly.

Thanks, 1200TS: I looked on eBay and purchased two sets of two off two 2007 Ninjas with low miles. I noticed most sellers are selling knock-offs from China so Buyer Beware. I asked the sellers:
1: OEM KP03?
2: Miles?
3: Tested for spark?
I did install TEK's on my SFC triple. See photo. Was hoping to use the Dynas on the RGS.
Thanks for your help!

You're right - they're Dyna minis, DC3-3s.

Hm, strange; the bracket was on the bike, but I could be mis-remembering.

What's wrong with my crimped brass connectors?

Thanks,

Opinion can be a little divided, although I’ve personally found that good quality brass spades are fine. However the ones in the photo look a lot like the cheap aluminium version, which are well known for poor crimp, corrosion and vibration damage. Piet who works with this for living has seen more problems than most 😉
 
Those pre-insulated connectors do not crimp the wire, they're simply squashed over it. Might hold up well in a clean, dry, vibration-free environment such as a car dashboard, but not much good on a motorcycle for any extended length of time.

Even if they are brass, which is good, the connection to the wire itself remains flimsy and failure prone.

Pay for a high end crimping tool and source the good stuff - very satisfying squeezing that handle and seeing a perfectly folded over wire and insulation connection. :D
