Great help to someone who is considering the kit . Thumbs up and subscribed
Good video, you explain very basic questions that everyone’s wondering so thank you
Awesome vid ! I’m about to purchase a 1275 kit for my 2000 1200/ w screaming eagle heads that I’m sending out to get cleaned up looking to get the bike to 110hp !
Congrats, gonna be a fun bike for sure.
Get the full kit from hammer performance. 110 kit will run 4300 total but that includes everything carb, manifold, air cleaner, cams, headwork, pistons jugs, ignition. you sould make over 110 easily. i got 117 out of my kit and ive seen 120 with the same 110 kit from hammer.
Mine are 2004, 2015 and a 2017 Sportster low 1200..all have a fuel gauge the 2017 has 4inch Vancel&Hines. No popping at all on all of mine. They we're. Worse from the factory. embarrassing...plus here in Florida,I've got Harley oil coolers on all and I switched from Valvoline full synthetic to Amsoil and the red in the tranny.. shifts like butter and all are Stage ones!!!.I'm anxious to put these kits in..should blow off a 114,, easily...love my Sportsters
I had an Iron that I put a Hammer 1250 kit on, no complaints about the kit. The brakes and suspension could have done with a simultaneous upgrade. I've now got an '07 1200 Roadster with twin discs I'm considering putting the 1275 kit on. After having an Iron I decided the heavier rubber mount frame needed heavy duty progressive springs in the front with a fork brace, and sorted the rear with Night Rod shocks that went straight on with spacer washers, and they've never bottomed out AT ALL.
+Martin Smith brakes do need a bump up.
Well done.
Great video!! I am going to tear mine down this winter and get my kit installed.
It will be a completely different bike! Good luck with the install.
GixxerFoo :- Did you ever fit a 1200 kit ?
I agree with everything in this video. I love my XLN but it’s underwhelming
Good stuff
Thanks for watching!!!
How is the temperature in traffic does it run hotter? Thanks for the video
So did you enter all the information manually? Or sent the information to Vance and Hines. Sorry watched your other video were you stated you input the information one by one. Just curious. I would love to just send the info to Vance and Hines and save the hassle
What was the FP3 map you used?
Finally! A hammer vlogger!! Didn't think this day will come.
+Geoff I'm a fan.
This is good stuff, Hammer has been the best about getting me where I wanted to go with my Iron, period. The thing is a beast now.
+Aaron Hightower I agree, those guys are extremely helpful and make a great product. Thanks for the comment.
+Aaron Hightower Thanks, Hammer is a game changer for sure. Ride safe.
Cool! Loved the content. What was that music especially the intro?
+Jeff Tilghman it is a copyright free tune from RUclips. Don't remember the name sorry. Glad the videos are helpful. If you have any questions please ask.
Excellent video, thanks for posting this information. I'm planning to get this kit for my sportster also. I have an '01 883, so it's a rigid mount with a carburetor. I'm planning to get the Mikuni flat slide carb in addition to the 1275 kit, as well as having Hammer port my stock heads and do a valve job. I'll probably go with a set of cams also.
Did you change your exhaust system too? I've heard the two into one thunder header is good with this kit, any thoughts on that? Anyway, nice video and it was great to hear your comparison to stock. I was really curious about how it feels compared to stock.. Nice job!
+Trevor Jameson Thank you, as far as exhuast I run the Vance & Hines short shots. I heard the thunderheader works really well with the hammer kit. Ride safe.
Nice work! My question is about the compression ratio with the stock 883 heads, most of all the 1250, to 1275 kits have 10.5 compression ratio, so with the 1275 kit you have with stock heads does the 10.5 compression ratio kit the one you ordered? I plan on doing the same thing on a 1997, 883 stock heads N4 camms.
Wish people would actually answer the question. I’m at the same crossroads
Is that a stock speedometer? I need that on my iron lol
Question: Is there any negative to keep the stock crank-wheel assembly if it is designed with the 883 pistons weight / balance? Or do you need to rebalance the crank wheel assembly for the bigger pistons?
Very good video and good day.
You don't have to do anything to crank.
handlebar brand ,model??
thanks!
Are those handlebars on back to front?
I got a 14 sportster 48 with VH short shots and fp3 fuelpack. maybe you heard this question over and over but, you didnt need to tune it at hd or any other place?
No, but it is recommended by hammer. I ran 3 autotune sessions on the base map from hammer and the bike runs great. I might squeeze a little more power with a proper dyno tune but I am very happy with the results that I have.
I love how the bike sounds stock.
I just installed the 1275 kit and cams I just finished my 50 Mile break in phase and about to start my 500 miles just curious when did you really start to notice the increase torque and power was it after the 500 miles and the auto tune or was it immediately after the install thanks
I could tell a difference pretty much immediately after the 50 mile break in. After the 500 mile break in and few auto tunes it really came to life. It will be a completely different bike after you get it tuned in.
my Sporty is an 883 with i believe the screamin eagle kit but i describe it the EXACT same way my bike is a BEAST i can pass anything except a gas station. well that and Bees and wasps its a bright orange sting magnet...lol..again nice video Mr Cox
Thanks, the difference is amazing. Ride safe.
Hi! I have s 98 1200 and thinking of putting in a 1250 sns kit. Maybe even changing the heads. Do you think it would drasticly change the horsepower?
+Dominique LeBlanc I think there would be a noticeable difference depending on what stage head work you have done. 1200 to 1250 there isn't alot there to make a drastic difference but add in headwork and maybe a cam and your in business.
Thanks. Just looked at the hammer prices and it's cheaper than sns. Maybe go with the 1275. Looking foward to put it on.
Dominique LeBlanc Depending what you are wanting to spend . In 1997 i won the AMI brute horsepower shoot out for 1200cc stock bore and stroke with 120. 2 . I also held the AHDRA B STREET CLASS 1/8 et 6.20 1/8 mph 112 and 1&4 et 9.87 . The heads flowed 185 cfm @ 11 in Used Ross 12.5 comp pistons redshift 763. Cams jims roller rockers jims lifters . The key is the heads SAMS PERFORMANCE CHARLESTON SC .
Dominique LeBlanc
Dominique LeBlanc dont know if you still researching. If you want to improve then definitely plan on upgrading your heads as well. Your stock 98 heads do have poor flow, old style ports and poorly shaped combustion chamber. Consider some ported Buell heads if you go with the Hammer kit, but also consider some bigger manifold (depends what will the cfm of your heads end up). Also research your riding style, maybe you need different cams timing to better fit your needs. Also if you are able use race fuel permanently then you can up the compression to gain more torque. If you end up with more then 100rwhp you will also need bigger carb, otherwise your stock carb should be enough and its easy to tune.
Good job...I've got a couple 1200 Sportster low ts..I've was told there's a kit to make 1200..bigger and better almost like a V-rod type horsepower. Any truth to this???
Hammer offers a 1275 kit with cams and a port job thinking 120 to 130 hp which is a lot for a sporty. I would give them a call they are very helpful.
Well thank you. I did not know this.but I'm glad you were able to get back to me.i sure appreciate it. Hmm I was getting 46-49 mpg.. lol I sure won't this time. Thank you
What website did you use to get your hammers 1275 conversion and your clutch spring?
www.hammerperf.com/
Thanks for watching ride safe
What is the combination that you used?, I have a 2013 48 and I'm planning on do a cam upgrade 570's or 560' and later to upgrade to a 1275 to finish.
I just changed out the jugs and pistons kept my stock heads and cams. Just the straight up 1275 conversion.
Tony Cox, did you correct the air fuel mix with the fp3 auto tune?
Tony Cox, what piston option did you chose? Flat head, square dome, etc?
Yes I did. Hammer gave me all the values.
Reverse dome with the 10.1 compression for stock 883 heads.
I wonder if its worth it to put it on my 1200 sport if it would be worth the money for the lil ex horse
I’m not sure just adding the 1275 conversion would be worth it by itself. Add a cam and port and polish the heads would make a noticeable difference. Ride safe
My first gear on my 04 883 is literally useless. As soon as i get going, i have to shift. Any way to fix this
Change your gearing, the 883 is shorter gearing than the 1200.
I thought you had to change the head if you had an 883 fue to a valve clearance issue. Or do the have a kit for the 883 heads
+charlie perry I purchased the plain 1275 kit from Hammer and the stock heads work just fine no clearance issues at all. I talked to Aaron and Hammer Dan before buying both are extremely helpful and hooked me up with exactly what I needed.
Tony, did they ever mention weather or not you'd have to change pistons out if you wanted to change the heads out later on?
I was told you need to change the pistons out if you do head work to compensate for the compression.
@@TonysGarage well that's a bummer I was thinking of just a 1200 head with bigger valves may have to give them a call to double check so
@@TonysGarage *soon
How much did the 1275 conversion kit cost? Hammers website says $900 but when I added up the items was more like $1500. Looking to power up my 02 sporty 883. Thanks
Thinking I was right around 1100 all in
@@TonysGarage thanks Tony, after doing some research I'm leaning more toward the 1250 as the most bang for the buck. Thanks for the reply
I already had the tuner which helped in price. The pre installed piston are a must in my book I think it was 75 extra.
@@simms196 alllllll of the power is in the head porting and the cams. It's worth the money to do it all. 1250, porting heads, cams. Your stocm 883 heads are not designed to work well with a 1250. 1250kit, stage 2 porting and hammer570 cams. It would rip. Ton of midrange
@@fvgc454ss They make a pretty nice looking Hammer air filter too. In 4th gear, apparently the 883 transmission cruises the 1275cc conversion engine at a higher rev band than 1200's with a 5th gear final drive ratio. My question is it worth swapping in a 1200's 5 speed transmission case and running 5 gears. Does the ecm work okay with an extra cog?
If running 11.2:1 compression pistons, high lift cams fitted, and maybe outputting 8000-8500-9000 rpm redline with some bottom end work and some porting.. wouldn't the 4th gear final drive ratio's rev band at the same speed as other bikes be more noticeable on a highway? To certain other people who might be watching?
Did you run auto tune on the fp3 after they sent you the new program?
I did but I kept their tune also.
Is it normal to experience increased valve train/rocker noise after the conversion? Is it because of the pushrods not being adjustable?
Where at Top dead center when you installed the pushrods and head?
@@TonysGarage No my question is a general one, I have an 883 converted to 1200 (all took place at a dealership) and also installed performance cam and performance valve springs
If they used synthetic oils after the swap then yes your gonna hear increased noise.
@@TonysGarage Thanks!
“ it’s really hard to reference speed and torque...” 0to60 and 1/4 mile, before and after work really well🤓
I meant visually getting it across on video.
Tony Cox You could video you doing 0to60 before and after. Lol
I can say this I went from about 47hp to 80hp almost doubled the bikes power. It moved down the road pretty good. 0-60 my M8 softail slim wouldn’t stand a chance.
Tony Cox that is impressive
Is your engine running hotter now we the 1275?
+Edgar Bustillos Not at all about the same.
I wounder what would be better performances wise and for just natural progression as a new rider getting a Iron 833 then upgrade it or getting Iron 1200 new then working on it or not much of a difference
The iron 1200 is a cheaper option than upgrading a 883. Add a stage 1 to the 1200 and it will be a very fun bike.
Thanks
Did you notice any difference In fuel economy? I assume so. Just wondering how much difference
I really didn’t notice any difference at all.
Thanks for the info. Looking at building a chopper and if I find an 883 was going to big bore during the process.
I'm about to order the kit, but I am a little intimidated about the installation :/
I was also, the service manual will be your best friend during the process. Take your time and take lots of pictures for reference. You can download the instructions from hammer and just read over them a few times before you start. Good luck feel free to ask any questions you have. Ride safe.
Tony Cox thanks tony! I was able to find sportster service manual online and I’m going to download the Hammer instructions. I’ve been reading the Top End Overhaul portion on the service manual and it says “discard” to washers, seals, gaskets, O rings... did you discard them or keep them? Does hammer supply you with new ones or do I have to get all this in advance?
I’m able to use the garage at my work for a weekend but if anything happened in installation I’d have to get the bike out of there come Sunday night. How long did it take you to do the installation?
Thanks!
Order the gasket kit from hammer it will have everything you need. I took two days. One to disassemble and label and organize parts and the next to put everything back together. Just take your time and double check everything. You can do it in day but it would be a long one. Good luck
Tony Cox thanks again tony! I enjoy all your videos! I’ll be familiarizing myself with the manuals well in advance. I’ll be ordering the kit in a couple weeks then have to wait for it to be shipped to Canada. I’ll have plenty of time to plan and setup. Happy riding!!
Tony Cox hey tony. Ordered my kit today!!! So excited. Aaron from Hammer was awesome! I'm going to start programming my FP3 and make some cardboard organizers for my parts. what did you use to cleaner your parts, specifically the bottom of the jugs under the gasket?
How is it holding up
Unfortunately I traded the bike in for a new softail slim, but I never had a problem with it ran very strong. Thanks for watching and ride safe!
Can u still run 883 exhaust
Yes sir
It's too bad the bottom end is so weak ( well, at least compared to the bottom end of a 1200 buell)) ,, you can do a conversion, using a buell bottom and in these bikes, ( you can pick up a used 1200 buell engine for about 1k bucks) you have to get the sportster case machined to accept the buell crank ( it's not expensive, most shops are familiar with the mod) , for the price of a used buell engine, some machine work, you can have a 100hp engine, the bottom end is much stronger, will rev to 7k as much as you want with out worry, you also get a better oil pump. For 1k bucks, plus machine work, you get a sweet bottom end , crank androd, you get jugs and pistons, cams lifters, heads, you get a much better oil pump, you get all the parts for the primary and clutch, for the price of a used buell engine, it is hands down the best way to build a beast sportie.
How much was the kit for your bike
If I remember correctly it was about 1200 bucks all in.
How much did it cost to do?
About 1200 to 1500 if you install yourself. Thanks for watching👊
About how much was the cost
It’s about 1200 all in.
$1200???? I’m seeing $1585 without the specialty tools
What are ur bars
Biltwell friscos
@@TonysGarage what size are they
Only for 883? Or any type of sportster
They make them for all sportster.
No
Head work will show the real gains in this 1275..
I agree, with the basic conversion I almost double my hp and torque. Thanks for watching ride safe!
@@TonysGarage Copy! Good work on the vid, .....
Another grand
GET THE HEADS PORTED AND FLOWED OR IT'S A WASTE OF TIME AND MONEY DOING ANYTHING !!!!
I put a 1250 kit on my '06 XL1200R and was a bit disappointed - I already had Andrews N4 cams and I found that there was not a lot of difference really because the heads didn't flow enough.
I tried fitting a bigger carb (HSR45) and still not much difference.
THEN I got my heads ported (over here in England) and fitted Hammer's Impact 560 cams..... it is a different bike now !
Don't bother with enlarging the engine capacity unless you port the heads as they cannot flow enough in standard form for even the standard capacity and cams.
What is worse still is going from 883 to 1200,1250 or 1275 without touching the heads - the engine stops producing any more power at 4500rpm as the heads cannot flow enough air never will even with porting unless you get the top level of porting from Hammer Performance - get 1200 heads if your budget won't stretch to their prices.
Although going from 883 to 1200/1250 or 1275 may seem great all it is doing is showing you how pathetic 883's are.
Take two test rides at a Harley Dealer - one on an 883 then test a 1200 and you will see what I mean the 1200 is TWICE the bike that an 883 is even in standard form - NEVER bother with 883's.
Disagree.
Power gains from a head kit on a base 883 are way more noticeable than on a 1200, not to mention it's also a significantly cheaper platform to hot rod. It's no surprise you noticed little gains from a 1200 to a 1250. IMO that's not even worth the trouble unless your doing heads and bottom end, which in the end will cost a lot more than just starting on a cheap 883 to begin with. Also, some guys prefer the 883s gearing to the 1200.
883s are also cheaper to insure, and no one besides you will know it's had a motor overhaul.
And a lot of dudes, myself included, doing a hardtail chop and stretch don't need a 120 hp bike...
@@cop70s So let me get this right, My comment was that you need to get the heads ported as they don't flow enough, especially 883 heads when you up the capacity.
You disagree with my comment but then go on to say that 883's really benefit from porting the heads..... If you cannot see that you have just contradicted yourself then I will not bother explaining it to you other than to say the heads on 883's are not the same as those on 1200's.
Try riding an 883 and then ride a 1200..... the 1200 is twice the bike to start off with. As for your situation of chopping your bike and hardtailing it, well if that is what you want OK but I 'and most other Dudes' get a bit bored travelling long distances on a bike with a cruising speed that is less than the average Highway speed of cars and trucks, not to mention that you will not have enough power to pass other vehicles and will limit the distance you can travel due to the severe discomfort that hardtails cause.... or are you just building it so you can look real cool down at the shopping mall ?
@@thakery5720 Nope. Not what I said.
My point was that the 883 is a better platform for jug conversion because it provides more power gains than a stock xl1200 would. A 1275 Hammer kit on an 883 will outrun a stock xl1200 in low gear all day long. Its just a much higher quality kit than the oem harley parts.
You will see more power gains from an 883 to 1275 than a 1200 to 1275. Not sure whats so difficult to understand about this.
The conversion on a stock xl1200 is nearly pointless unless you do heads and cams too. Because of the gearing, the 883 doesn't REALLY need head work unless you want to actually gear up the sprocket and do more high rpm riding.
Go to the Hammer website. All the info is there.
Btw a 1275 kit on a stock 883 adds like 30 hp...more than enough for highway riding.
And there is a huge subculture of EVO chopper guys all over the world. And yes, it's all about looking cool.
Why not do cams and head work all the same time that way you actually see a significant power gain
The gain I saw where exactly what I was looking for. While cams and head work would provide more hp for sure. It was just something I didn’t need at time.
That power vision how much of a nightmare to install cause it looks like theirs a lot to it
Hey Rob, the install is really straight forward. Can be done in a day. Just take your time and take lots of pics during the teardown. 100 percent doable. Ride safe.
FP3 are not a best choise for any modified bike, works on stock bikes.
