I'm happy with the 1250 kit I got from Hammer. It really makes a difference. I have the stock 883 heads and gearing, and I don't feel like I need any more power. If I intended on cruising on it, I might change the gearing, but for my purposes, I like the stock gearing. It pulls like a freight train.

Hey Billy, not sure if you have committed to anything yet but I too will attest to the excellent system that Hammer has put together. I lucked out and just bought a bike that had the 1250 100hp kit already installed. I won't say how much I paid for it, but rest assured, I should probably be behind bars. I'm 6ft and 225lbs and I am completely satisfied with the ride. If I want to cruise or commute, I do so without worrying about reliability issues. The bike is completely rideable in every situation I've encountered. If I want to go, it goes. If I want to cruise, it does.
Further to that, I'm not a bike tech by any stretch, but I do have some experience with various automotive motors, and I reccomend you heed the warnings offered already with regards to the mix and match method of engine building. All the major players of your motor work in an orchestrated dance to optimize power while maintaining efficiency and reliability. Best to keep everything that is designed to work with one another doing exactly that.
Please post back when/if you have made a decision and how it is/did go.

IIRC Hammer has some performance graphs on their website, which show the various stages of tuning, using their products. IMHO the biggest improvement comes with the basic conversion, which boosts torque and power substantially. Other tuning improvements, such as bigger valves, a change of cams, etc, add much more power, but relatively little torque. Should I ever bite the Hammer bullet I will certainly stay with the basic kit, as that matches best to the style of riding I do. But I do have a Buell Firebolt for the serious motoring!

hp and tq are related so what you’re saying does not make any sense at all. Any time you want to compare tq on my dyno charts with both my top shelf 1250 and 1275 against a basic conversion let me know. We can also compare the hp curve too, since they are related with simple math.

GRBROWN, are you posting this graph to make a point? This just compares factory hp of an 883 with two set-ups from hammer. They have hundreds of different combos that they can build, so how does this validate your statement about the basic kit being the best one to go with? I recommend you contact them directly to discuss costs and results.
also, why did you quote madnss on this? The chart doesn't display tq, so how does it pertain to what be said?
