Hi.

I´m very confused, some say this some say that.
I just finished the 883/1200 conversion, 9,5:1 Wiseco, Carb rejetted and SE kit added, Santee mufflers no other work done.
(stock ignition, coil, cams, heads etc.)
Will a Dyna 2000i do anything for me? Do I need additional stuff (1200 or SE ignition box)
Singel fire? is that the way to go.
Is Dyna "better" than Crane, Accel etc.?
Please enlighten me

The stock ignition and coil are plenty for most street applications. That meaning that as long as the powerband you have built your engine to perform in isn't interupted by the stock rev limiter. And again, for most street applications, the stock advance curves are fine and no gains in performance can be found by buying an aftermarket ignition or coil.

If you get into higher compression (say over 10.5:1) and longer duration cams that will need to spinn higher rpms, then keep the stock stuff, and save your money.
