The packaging saying Drag Specialities just made me suspicious as you described them as Dyna ones - lots of other brands on the market that work - my 500 has some cheap ones purchased locally.
What I do like about the coils you have is the plug in leads I am no fan of the original Honda design. I would be interested to know the supplier if you have a link. Are the bolt centres the same as the original as well?
ComfySofa:
Heres what i ordered....i searched for Dyna Coils....they do look and feel like Dyna coils....heavy in weight and the same feel (from what i remember) re the casing feel...

My old GSXR ones (from recollection were yellow in colour) and had the same exit angle for the HT leads....i kinda assumed that they were therefore dyna...might not be though - i must confess i didnt pay that much attention...!
Furiously googling now....yeah appears i dont have actual "Dyna" ones....return or no? what says you lot?
Found them on the net.... https://www.arhcustom.co.uk/brands/drag-specialties/drag-specialties-ignition-coils/?gclid=CjwKCAjwu4WoBhBkEiwAojNdXnmGsixawd_6TrN-hooqUKsH8TrH0shry28nMxjlCQ24k7k2vX0AUhoCnRkQAvD_BwE
Anyone got any reviews/feeback??
Edit - found a range of reviews...cant see anything bad about them- different models but they all seem to be happy with them....and i will say they do have the look, feel and the weight of Dyna's..

Dynas do have some known faults. Normally the ohm resistance is wrong, that's been known to cause problems. The biggest drawback though is how much more power they consume than standard coils, can't remember offhand but do remember it being listed by Hondaman as excessive compared to stock. As the amount of power on the SOHC bikes is also a known issue any additional draw is best avoided if at all possible.
I'd have mounted them the other way Ted, facing forward you have wind etc pushing moisture into the opening where the leads exit, facing backward you don't. They should fit either way so why not take advantage of that.
Biggest drawback IMO is the cost, fixing the standard coils is normally miles cheaper and thanks to the Ash fix that's now easy to do. Plus then you get the correct impedance, lower current draw and better fitting. Along with electrical connectors are spot on.

Well, - ive got a set of oem honda coils for sale (only done 6.2k) :)

Fix them, worth more and you never know what might happen in the future.
