ive had a amr coil and cdi (stage 2) on my ex for about a year now. i cant tell you i noticed a huge difference and i didnt put them on at the same time. but i have never had any problems with them, other than the mounting holes on my coil were too short so i was only able to use one of them

I have a dyna cdi for sale pretty much brand new for 55 shipped half what i gave for it.Gives a 1000 rpms. I have a brand new programmable dyna ignition that is also for sale and i would take 230 shipped for it they are 350 brand new and this one has never been used.
