I have built quite a few Ironheads with good %26amp; RELIABLE performance using the following components.



First off, 5 angle valve job at minimum, even better is a RADIUSED valve job will be required. Find an EXPERIENCED %26amp; REPUTABLE shop in your area that has experience with Ironheads....Zipper's Performance in Maryland is who I have always used.......http://zippersperformance.com/ Have the guides replaced with hi-flo guides that USE VALVE SEALS....most Ironheads did not use valve seals and consumed oil excessively. Also use NEW Springs.



Use NEW Rocker Arm ASSEMBLIES....(Vtwinmfg.com, page 790)



USE KEITH BLACK PISTONS....KB makes a special angle top piston mated to the dome of the combustion chamber to create a "squish band" effect, eliminating the need to dual plug the heads, resulting in a MUCH BETTER %26amp; FASTER burn......http://dragspecialties.com/fatbook/6/324鈥?/a> .....Use a KNOWN REPUTABLE machine shop for the piston/cylinder set-up...KB pistons REQUIRE exceptionally close tolerances and a SPECIAL top compression ring end-gap!!!!.......FOLLOW KB's SPECS!!!!!



Use NEW lifters and pushrods. (vtwinmfg.com, page 788)



Andrews PB+ grind cams.....(vtwinmfg.com, page 787)



Daytona Twin Tec Igniton......http://www.daytona-twintec.com/model_100鈥?/a>



The old and outdated S%26amp;S Super "E" is a good old school choice in carbs, jetted with a 26.5 or 28 pilot jet and a 66 or 68 main.

My personal choice for a carb is to convert it to a newer HD "CV" carb, requires S%26amp;S manifold, rubber spigot adapter, CV-Style air cleaner, (this can be a pain sometimes but IS REQUIRED)- - - fabricated air cleaner-to-head (or case center-bolt) support to keep carb from coming loose and falling off, and daul CV throttle cables....with this set-up, you get GREAT performance!!!!....in the carb, use a dynojet EVO Sportster kit with a 45 pilot jet. DEFINITELY use a K%26amp;N filter!!!



DO NOT USE DRAG PIPES!!!!!.....they will kill whatever performance gains you make from any other mods!!!......DRAG pipes are for DRAG racing.....WIDE OPEN THROTTLE USE ONLY is the only place they make power....you WILL lose 15-20% of all low %26amp; mid range hp %26amp; tq, and this is where you WANT and NEED the power.

Use any decent set of aftermarket muffled/baffled pipes....even better is the original factory crossover headers with (GREAT mufflers) - - stock mufflers with baffle ASSEMBLY cut out (leaves straight through glasspack)...or...use a good set of aftermarket slipons.



If the crank needs rebuilt, talk to a local reputable shop, it may be more cost effective to replace the entire crank assembly.



If the trans needs ANY work....let a local reputable shop do this!!!!.....a 4spd Sportster trans is NOT for the novice!!!....they require CRITICAL set-up, clearances and end-plays, if ANY of these are set EXACT, you can and most likely will burn it up; bend, burn or break shift forks.



Use Barnett KEVLAR clutches and NEW SPRINGS and preferrably pressure plate.



For the basics.....I think this about covers it.What can i do for performance 83 harley sportster?
There's a lot to know about the mighty quad cam and I strongly suggest getting professional help on this.

I'm sure this is still an AMF year, as mine is an 81, I'll give you a brief in what I went through to get it to be the fire breathing import slayer it is today.

Wiscoe co 10.5-1 pistons, Andrews cams, EXTENSIVE head work, S%26amp;S Shorty E carburetor and a Barnett kevlar clutch.

Now back to the AMF thing. I too have built my share of 350 and 250 Bow Ties, well when putting the lower end together, I highly questioned the factory way of doing it, but was assured that it was fine. Got it going and enjoyed 3495 miles before something happened. Checked all kinds of stuff denying the obvious and worst thing. With the engine off (couldn't turn it on) I put it in gear and pushed it fine.

My flywheel had come apart from my output shaft. No key you see.

Took it to somebody who knows better and got it machined as well as a bunch of other little things I didn't realize.

Get it done right the first time and enjoy the awesomeness that is the Quad cam.What can i do for performance 83 harley sportster?
