Hi there,

I was wondering ; I may have a good deal on a complete SF engine with a 181 S Stage mounted on it.
My idea was to swap my OG stock engine with this one, this way I could reverse to stock if needed and worse case scenario I'd have a donor just in case with the old stock engine.
Plus : A new engine (by new I mean more recent) is a bonus for my 2013 OG Grom.

My question : Is it, how I think, plug and play ? It won't come with anything else than the engine itself. So I'll plug it to my existing harness (same ?) and to my stock FI system (once again, same or same enough ?). I intend to add a Fi Con 2 to tune it accordingly.
Oh, and of course, I have an aftermarket exhaust and a modded airbox.

So, SF engine compatible with my OG grom ?

Thank you :)

Greetings from France !

I know the stators are different. I don't know what you have to do to use an SF stator on an OG but the info is probably on here.

Oh, yeas, interesting, thanks.

So perhaps mounting an SF rectifier when doing the conversion is something to consider.
Since it's around 20 bucks on eBay, that's probably a safe thing to do.

Any other thoughts ?

Oh, okay, good to know, thanks :)

So if the engine comes with no cable or sensor whatsoever, will my og o2 sensor plus into the engine or should I go and buy an SF sensor to be sure?
