883 to 1200 Conversions:
Chandler Harley-Davidson recommends the following to upgrade a Sportster 883. Anything less than going with this upgrade may result in disappointment in performance. S/E high flow Dynojet kit,m Buell Thunderheads. Buell cylinders & pistons & pistons kit, all necessary gaskets. Installed $1,709.99
To further enhance the 883 to 1200 conversion, you have the option of the 42mm SE flat side carb (Mikunie) or the big bore 44mm CV carb. Cams would be next: a set of XL bolt in cams (25649-01) for loads of top end power. You can accent it with the Screaming Eagle selectable curve racing ignition module. Then you can finish it off with a Van & Hines 2 into 1 pro pipe or my favorite, a Thunderheader. That will make it bark.

RE: Upgrade a Sportster 883 to a 1200
To upgrade an 883 to a 1200cc XL Sportster for $1,000 is a little tight but can be done. I would use off the shelf pistons, gaskets etc., but bore and hone the cylinders to size. This will be slightly less expensive than buying new cylinders and would match the new pistons perfectly.
We will start with removing the top end for cleaning and inspection. Next we will bore and hone the cylinders to match the new pistons, install flat top pistons and measure combustion chamber volume. We can adjust volume where necessary by gasket thickness, etc., to give correct compression for stock cams and pump gas. The compression should be approximately 9.5 to one. All clearances will be checked; squish band set to 0.40", piston end and side clearances will also be checked. Now we have the cylinders and pistons installed. Our stock heads need attention; due to the cost factor, I would replace guide seals, freshen up the valves and seats in order to get a tight seal. I would also clean up any rough spots in the ports and combustion chamber; this is where the power comes from due to the small valves and the increased displacement.
It will be necessary to change the oil and oil filter once the heads have been installed; new engine parts need new, clean oil. Now we are ready to re-jet the carb, 45 pilot, 175 MJ will be a good starting point; a few additional modifications will be made to the carb so that it will react quicker. Pipes, stock ignition, stock cams will work just fine for now.
After 500 miles or so I would do a final tune and check over. This little conversion should see about 65 to 70 HP and around 65 Ft. Lbs. of torque on the dyno.Sincerely,

The most inexpensive way to achive this would be to take the stock jugs and have them bored out to 1200 spec. Then replace the pistons and rings with the Wiseco 1200 piston kit. We would also suggest a Dyna Jet kit be installed onto the stock carb. There is not a whole lot extra that can be done to the motor with out going over the 1,000.00 dollor ceiling.

Hacienda proudly recommends the following conversion from the stock 883 Sportster to a 1200 Sportster. We recommend off the shelf parts for two reasons. The product is instock and the upgrade can be done without using outside machine work and we feel the the finished project will be more reliable. Please see us for upgrade that could be installed for a minimum price while we have the Sportster apart.

Following is my recommendation for upgrading an 883 to a 1200 Sportster. To stay within the budget this will be a basic upgrade. To complete the conversion, I will provide a Free Dyno tune and then will make the final adjustment with a proper jet to the carb, depending on the dyno testing. This should give you the maximum power with the limited budget. If you would like to expore possible upgrades to maximise hp vs $, please let me know.

AZHD recommends the following components to be
installed. The list contains the most cost effective
way to perform the upgrade. All parts included are
factory Harley Davidson parts. This will eliminate the
potential for mismachined components.2 Screamin' Eagle cylinders part# 16554-92A $279.90
1 Screamin' Eagle piston kit part# 22698-01 $279.95
1 Harley Davidson topend gasket kit part# 17032-91 $66.65
1 Screamin' Eagle Dynojet kit part# 29045-97A $74.95
1 Screamin'Eagle ignition module part# 32978-98A $119.95
Parts total, not including tax, shop supplies, etc. $821.40
Labor to install 8 hours @ $65/hour $520.00The total for the job exceeds the $1000.00 limit, by
approx. $375.00. If Romaldo wanted to stick to his
budget, he could eliminate the Ignition Module. This
would save approx. $200.00. If he wanted to go one
step further, he could also eliminate the Dynojet kit.
This would save approx. $150.00. I personally would
not recommend the elimination of the Dynojet kit. A
poorly tuned carb setup will leave Romaldo
disappointed. Yes, some "Popular Carb Mods" exist, but
they do not compare to a properly tuned jet kit. Being
that a jet kit is tuneable, the window for
misadjustment is large. This is where most lesser
mechanics fail.In closing, Romaldo will end up with a quick street
bike, capable of approx. 60 horsepower. His usable
torque will be broad, because of the use of the
quality Screamin' Eagle slip-on mufflers, and
Screamin'Eagle hi-flow air cleaner kit.Any questions Call JD or Jason

480 833-4683 PhoneHey Kirk.Romaldo can get quite a gain in performance for a $1000.00. The Screamin Eagle mufflers and air filter kit are a good base to start with. The prices here are what I would charge if I were to do the job. If it were full retail it would go over Romaldo's budget. But since we don't ever charge full retail on service I am able to do a little more.

At this point, most customers like to install performance cams. The most popular is the Andrews N2 @ $250.00 for a set of 4 cams.
New Harley-Davidson lifters are $130 for a set of 4 (w/ small "bolt-in" cam shafts). I find there is no need for more expensive lifters, the factory lifters work fine.

Following is what was presented to the
Dealers and shops here in the valley
Project; Upgrade a Sportster 883 to a 1200
This objective, should you accept, is to provide your recommendations of how to best upgrade a Harley Davidson Sportster. Following you will find information on the upgrade request and the bike that is to be upgraded.
This is a great way to get your name in front of a large audience. Currently I get about 2,000 to 4,000 hits per day. I know that this project will create interest, as a lot of the people that I talk to would like to increase their power. Now you have a forum to provide your technical knowledge.
Please, I need this information back by Nov. 27th. This will then give me time to post the information on my website at phoenixbikers.com.
Project Bike for Upgrade
Bike Harley Davidson Year 1999 Model Harley Davidson Sportster 883 Mileage 6,000 Miles Modification Screaming Eagle slip on mufflers
XL High-flow Air Cleaner Kit
Note - Carb has stock jetsOwner Romaldo Perez
Objective: Basic Sportster 883 to 1200 Upgrade
Romaldo wants to upgrade his 883 to a 1200 cc engine. He would like your feed back on your recommendations for the upgrade. One of the considerations he has to make is to use off the shelf bolt-on accessories or have machine work done on his engine. Which would you recommend and why?
Please respond with the parts you would use. Include pistons, jugs (if off the shelf) and jet recommendations. While the engine is apart, what other modification would you recommend?
Romaldo does not want to spend over $1,000 on the upgrade. Can that be done?
I will send this request to all of the Harley Davidson Dealers in the valley and all of the Custom Bike shops listed on Custom Bikes page at phoenixbiker.com.
If you need to check out the bike before responding, please let me know. I will arrange for a meeting.
After I get all of the responses, I will put together a report that will summaries your response and publish it on the web at phoenixbikers.com.
I assure you that no one will know who responded or what the response was until it is published.
