For me, yes, but I'm 6'2" and have used rearsets so the whole riding position is changed.

They're great to deal with - got clubman bars from them.

Its all a bit of a nightmare isnt it!  You can see why people the world over recommend running standard ignition components, but equally its easy to understand why people are tempted by promises of (relatively) maintenance free ignition systems. 

Sounds to me like you've done your homework and in theory everything should be fine, but I guess this is all part and parcel of running an old four.  Blood, sweat and tears!  Oh and of course lots of money!
Definitely money!!

Will deffo have the writeup  done on standard coil refurb. Just building up a test circuit. My take on it is that the weak link is the PVC outer on the HT leads. The 'coils' themselves are extremely reliable. With age the PVC hardens really badly and the inner core fatigues. This happens even on low mileage bikes.
That's exactly what has happened with my leads - the PCV has cracked down to the core right at the point where the lead enters the coil. 

The coils themselves test perfectly good.  Primary resistance tests bang on 5.0 ohms, secondary resistance is between 15.3k-14.7k ohms, continuity between primary circuit, no continuity between primary to secondary.

I've read that before - I bought the 5 ohm dyna coils because of the low alternator output and I intend to use them with the Dyna - S. I also converted every light to LED to reduce the draw on the system.

Be careful with the DSS pattern coils, the ohms are not the same as originals. Sorry cant remember what the readings were, but it was off by enough for me to return them. Got it written down somewhere, plus Ash will know as he talked me through it.
So where did you end up going for a 5 ohm coil and what was cost like?

NNNNNNNNNNNNOOOOOOOOOOOOO........don't buy those they are absolute rubbish.  I bought a pair and had real bad problems which made me think the cabs were out.  Turned out to be a crap spark.  I had a set of coils kicking around the shed off a ZZR Kawasaki.  Stuck those on and the bike fired up like a trooper and has been spot on ever since. They were TEC KP02's which are 3.8ohms if I remember correctly.
Haha haha got it.  :)

Would you go for the coils from DSS or would these be just as good?  http://www.ebay.co.uk/itm/311350150677

Glad you found the problem, at least you know where your going with it. If you check on the web, Dyna systems are getting slated all over for being unreliable. Either points or Boyer Bransden for me.
I'm thinking points for now.

Great it's sorted. I was going to suggest Sunday but, as with most support problems, if you leave it the protagonist usually sorts it out 

Glad it's nothing really serious :)
Me too!

« on: June 15, 2016, 02:09:25 PM »
Hi all,

My Dyna coils have fried and will be going through the warranty process to get new ones.  Anyone have a spare set of coils they could lend/sell me for cheap to keep me going in the interim?
