1200 kit question
Whats the difference between the stage 3 1200 kit in the SE catalog, part number 29836-10A and the stage 4 part number 30003-10. We’re going to change my wife’s bike to a 1200 after this riding season and gear it like a 1200. The stage 4 comes with heads but not cams, the stage 3 says it comes with cams and bumps the compression to 10 to 1. I feel like the stage 3 is gonna make more power and it’s a little cheaper and the stage 4 is just an emissions complaint XL1200 spec kit, is this correct? The stage 3 does say it’s a race kit. I They both come with the heavier clutch spring. I am going to tune this bike with an FP3, it’s a 2013 superlow.

The 30003-10 comes with 1200 heads with larger valves and Sportster High-Flow Air Cleaner Kit.

07-Present XL1200 Heads
62cc chamber, 1.810" diameter intake valves, 1.575" diameter exhaust valves
07-Present XL883 Heads
49.5cc chamber, 1.585" diameter intake valves, 1.350" diameter exhaust valves
I would ask Hammer Performance about the which would give the highest performance. I suspect the 1200 heads would perform better.
You might consider one of their 1275 kits.

I recommend you investigate Hammer Performance kits first. A simple 1250/1275 kit gives a serious bump in capacity, CR and performance, for much less outlay than an H-D kit. The bone stock 883 heads provide great performance, or can be economically improved without buying new ones. There are many members who have built Hammer bikes and plenty of threads in here on their builds, showing details on 'how to'.
The most noteworthy thing IMHO is that the biggest benefit of their big bore kit comes in the low/mid rev range, where most of us ride (quite probably including Mrs M!). Further changes, such as head porting, cams etc mostly improve the top end. I suspect your wife will be blown away by the improvements from the big bore kit - and impressed by the 'bang for buck'! Leave the gearing as it is.

nothing wrong with the se kits. stop the nonsense.
hammer tends to put more goodies in the box like actual clutch upgrades, not the clutch "spring" in the hd box. hammer also sends tunes, hd tries to molest you for tunes.
i'd say skip the fp3. go with power vision. too many issues there... unless the bike in question already has one.
1200 kit
stage 3 kit
stage 4
there's pros and cons to each, pick up the phone and call around.
hammer (208) 696-1250

30003-10 is not stage 4, it's the full 1200 kit $990 before tune/download and install. in the case of this 30003-10 kit, you'll get off cheaper than hammer but, not be in a better position overall because hammer gives you more with the basic conversion package ~$1150 before install (if you dont do the work).

- hammer basic: http://www.hammerperf.com/883conversions.shtml#basic
29836-10A brings you up to 1200 but leave you with stock 883 heads.. not really better than the standard 1200kit. cheaper, yes @$825, a hammer blem setup is probably closest at this price point because you'd come out ahead for $499 and maybe cams. your call here.
- stage 3 $825: http://www.boardtrackerharleyonline....CE/NON-HILITED
- blems $499/ call hammer: http://www.hammerperf.com/garagesale.shtml
hammer is not cheaper for the same performance package (90+ package) as the se stage 4 kit. don't let folks fool you, it's actually about the same price and about the same performance. with 1200 cylinders for the se setup. cheaper if you sell off your old parts. (-400-500)
- hammer 90+ kit without power vision:$ 2250-ish http://www.hammerperf.com/samplepdfs/14+90hp1275.pdf
- se stage 4 with cylinders $2226:

Yeah it looks like the hammer kit is 1529 for her bike, the se kit will be a couple hundred bucks cheaper including the SE tuner from board tracker. I’m leaning towards SE because if the bike has a problem on the road a dealer should be able to help me out. Not really looking for a hot rod, just looking to make the bike run like a stock 1200 either way the power gets bumped pretty substantially. It will be plenty for her.

the clutch pack should still be replaced though. That grenade ring is in there waiting to blow. Enegy one btx-11 or barnett kevlar pack with the se kits included se spring will work.
would still recommend a powervision tuner over the se. It will be more useful down the line and comes with the improved stock 1200 stage 1 map (30003-10 is stage 1 1200)

Also, the oil pump drive gear should be changed to bronze as the stock one will grenade in high horsepower applications and you should replace your primary chain tensioner because that too is known to fail under high power.
As previously stated, at minimum you will need a 15% stiffer clutch spring but replacing the entire pack and spring is the proper way to do things.
The SE seems cheaper because it is just that, a cheaper alternative to more power without looking in to reliability in terms of other parts of the motor. For this reason, i chose hammer performance and have never had an issue at the dealership resulting from me not using their parts. SE is cheaper because it does not come with everything you need and you will have to purchase those parts elsewhere causing you to spend more when you can one stop shop it with hammer.
Spending a few bucks now will save you hundreds in the future in either repairs for failing parts or when you actually decide to change the remaining critical parts.
P.S. Harley lifters are ****, I recommend going with S&S for lifters as well as adjustable pushrods to double check and adjust geometry.

1200 kit includes a new clutch spring. It's reliable. Its just turns an 883 to a 1200. I ran it without incident for years.
No crazy hp. Op said they were going to switch out the gearing too. Hes just going 1200 stage 1. No werewolf engines... (subject to change, lol ...the more they read this thread..
