I am considering doing a 1250 conversion on my 2012 883. Can anyone give me some feedback on your experience with this procedure. Drawbacks benefits etc. Any info will be greatly appreciated.

 

There are a lot of post's on this. What I haven't found is do I need a new controller? I'm going to do this, but I'm looking to see how much it will actually cost. No one has said what it will actually cost. Sorry if I added more questions to your post.

 

My DIY 1250 conversion thread: EFI version - Harley Davidson Forums

give this a read I found it very informative

 

Supposedly FuelMoto is coming out with their own kit. I haven't seen it and don't know anything about it and have no interest in it so take it FWIW. I suspect it will be pretty decent.

 

NRHS has top notch kits and their customer support is great. They will walk you through everything you need.

From what I have seen around here, I know where I would be getting my kit. Either them or Hammer but right now, there is a slight lean towards NRHS. Thought I'd mention Jamie's kit just so the guy has an option. Not like NRHS doesn't get mentioned at least once a week here anyways.

 

Just use search for '1250' and you will find some very informative threads well worth reading, including a DIY with photos. NRHS is a sponsor of HDF and well worth supporting, and provides help in here.

 

IMHO there is no point doing the conversion and not unleashing the power of it. Meaning you have to replace some restrictive parts. You'll need:

performance exhaust
better air intake
proper fuel management
1200 heads (2004 or later)

Also you may want to change your gearing if you do longer trips or ride often on the interstate.

Add all that together, the cost of complete conversion will be over $3000, maybe even more. This is parts only. Add cams and headwork and you'll be in $5k range.

The drawbacks? Shorter life of your rear tire, slight move of your right wrist can earn you a speeding ticket ...

 

The costs stated by VZ was the reason that I decided to trade my 2012 Iron 883 for a 2012 48. It was about $3,000 hit on the wallet, but I got the engine I wanted in a couple of hours by doing a trade. The only headache was negotiating the trade and I can deal with that. I'm so happy I went this route.

Yes, it's not the 1250, but I guess that depends on what you are trying to accomplish.

 

I venture to offer an alternative IMHO! The performance gains of a 1250 kit are very significant and while a set of 1200 heads may further improve them, so will a ported set of 883 heads. However studying NRHS's graphs for the various stages of head work, I reckon most of us will be very happy with a straight cylinder swap, plus suitable retune. A very economical performance boost. Head work improves things in the upper rev range mostly, not where most street riders ride.
