    Hey guys,
    First time on the forums but wanting to know some info/opinions on the iron 883 to 1200 conversion. I’ve got a few quotes ranging from $2500 to $6500 obviously amount of work varies the price. Just wondering is it worth going all out and leaving no stone unturned with barells, cams, pushrods, throttle body etc (100+hp) or mid range which is standard conversion with cams?? Is there a huge difference in performance considering the price? 

    Regards

    Just a thought lad what's the change over price on a new 1200 ? Or a demo maybe save a wee bit there.

    Welcome. Check out these guys:

    Even if you don’t decide to use their products, the run down on how to extract performance and what is needed from a sporty engine is fantastic. Basically, if you stick with the 883 heads, options for cams etc are limited at best, with HP output similarly limited. Agree with above - unless you are in love with every other part of the bike, look at trading up to a 1200 maybe? TC

    basically  I would expect a 883 to have around 55ft pound of torque or (75nm) & a 1200 to have around 74 ft pound torque or 100nm. that is what you would feel the most.
    but as they come it is not just the engine size , it is also the heads 883has smaller valves than the 1200, as tc883 has posted Hammer have a lot of information on there page. years ago it was easy as both used same barrels , with 883 having a thicker linner than the 1200, you could take 1/4" out the bore, for some shops that takes a lot of time but I know a guy with a machine that takes 1/4" out in one run perfectly straight & true. but the new 883 does not share the same barrels. if your thinking you want a 1200 buy one, if an 883 works well for you buy that. you won';t save $ buying 883 then converting to 1200.

    Hey mate, I use to have an 883 with 1200 SS conversion with the cams now own a 48, 
    My input get it done properly with a good tune, it’s 100% worth it. I pulled about 90 hp and I can tell you it went harder than my 48 now. If your in Melbourne I can recommend a mechanic.

    I wouldn't do it. Get cams, tune etc but don't change the capacity. It'll never be "the same"
    You "could" have issues re registering / compliance / selling it. Who will want to spend the money you have on it when they can spend the same coin on another bike. It's not a classic.
    Hang onto it as long as you can then trade it.

    I bought it with everything done, re tuned it. My 48 needs a tune and would improve a bit. 
    Re sell vise I actaully sold mine for more than I bought it, you obviously won’t get the money you spent back, getting rwc wasn’t hard either. 
    Your call have a think about it weigh up your options

    thats cause of the small valves, the 1200 with the 883 valves could make more tq it's the tq you feel not the hp. also 883 has lower gearing. but you can gear a 1200 the same. you could put an 883 gear box Sproket on your 48

    I've seen stock cams on a sportster make more HP than after market cams. if you turn a 883 into a 1200 on the cheap, you will have a good performer and cheaper rego in some states. but depends what you want.

    Sage advice Steelo that applies to all bikes, I’ve never met anyone who recoverd the money they spent on engine mods, even accessories.
    Probably because wise used bike buyers associate engine mods with having been given a hard life. 
    It’d be an odd bod who hots up an engine just to putt around.

    well I've been lucky always had well set up motors that perform & last. all the Harleys I have owned all good performers and new owners won't sell them.
    but mass production is what stock is and works like that too, when you ride a well set up and fully hand built you would not be happy with mass production.
