Question:
I would like to know if anyone knows the stock cam lift for 2006 Harley 1200 Sportster Custom. They said that in 2004 they went to high flow heads yes I know this but they never give out the cam spec. I am trying to put together an engine combo but can't continue until I know the stock lift. It is part of figuring what ca,shaft profile I want to go with and how much I need to do to the heads. I have bulit many Race ENgines and Twin Cam Engines but never a SPortster or Buell. Thanks for the info.

I'm not trying to make you look foolish but have you tried to call the dealerships parts counter or tried Harleys website?How many motorcycles have you had in your life?
Dude, if your building a performance motor, scrap the stock cams. Andrews makes a nice set for sportys. Also try the moco's screamin eagle stuff. They perform very well! Good luck to you.O.K. tuff guy I read your additional comments and now it's time to smack you around. First off if your having a camshaft custom ground (which I highly doubt) the person should, no better have all the numbers for a stock configuration of an XL motor. If he don't run like hell. Secondly the '06 Sportster has the Xl EVO motor (don't matter that it's a custom). If your saying that Andrews and S&S cams are of a Walmart variety you don't know jack squat about building motors and maybe you should leave it to a professional. You also failed to mention if your going to change the stroke or if your using relieved pistons (which will obviously dictate what lift cam you can use). Anyway you fashion yourself as a race engine / twin cam engine builder. If you have built engines and are knowledgeable that info is very easy to find. Like I said your cam grinder should have it, but to make your life easy I called my machinest and here are the numbers. Intake open 224 degrees, exhaust open 230 degrees with a 4 degree valve overlap. Intake and exhaust lift are symetrical at .470. Like I said in your case (unless your a mechanical engineer that is familiar with engine design), I think your better off leaving it to a PRO.
