The ignition in particular is the only problem really. As I’ve been told on seperate occasions there’s basically two options; you’ve either still got the original DDR ignition that still works, or you’ve got the VAPE KIT (which is very good, but also not cheap).
Anything other than that and you’re in a world of shit. All available aftermarket parts for the stock ignition are of appalling quality. I can attest, I’ve got a ton of pictures and videos of where it broke down on me.
