Single fire--Dual fire
Hi,
This is a general question to those with experienced in ignitions for HD new and old.
I have a 1992 Electra Glide with the stock evo 1340. As I understand HD bikes from 1970.. to around 1997-8 are dual firing systems. After that HD went to single fire systems.
I have decided to change my dual fire to a single fire system using one of Dynatek's kits. My biggest concern here is, if I go to single fire and the down stroke side doesn't fire as dual like before, what bad points does this have?
I've been told the evo will run much smoother from 2800 RPM down if I switch to single. Does anybody have any experience with this?
The extra expense to make the move is another issue. Is it really worth it?
Thanks Mark

RE: Single fire--Dual fire
Well... on my '99 Night Train I decided to stick with dual fire as I don't think the single fire changes much of the smoothness. A couple of us had our previous bikes switched out by a retired HD old codger and when we picked them up he tricked us... He only changed one of the bikes, yet we all celebrated how much smoother they were in the low to mid range and later when he told us he only switched one of the two, we couldn't figure out which one it was until we went up head to head where one caputed at 5,200 RPM and the other kept going up....
Go for it, don't let my episode stand in your way as you will probably get so more performance out of the system.
I swear they were smoother, but now know it wasn't so... d@mn!!
