You can buy the components and use them in your cases...

I tried a few things that didn't work!

 Now when I get an Evo cylinder with baked on gaskets, I use a mandrel to hold the cylinder in the lathe and carefully skim it off. Often when I do this I find out that the base is no longer flat. There are areas that didn't "clean-up" once the gasket is mostly gone. It usually only takes a skim of a few thousandths of an inch to restore the whole base to flat. It's faster to do it this way than with the old Trock lapping plate. Going back together, I like to install oil drain pigtails (V-Twin 16-0912). To tap the drain hole I use a spiral flute "drill tap" (McMaster Carr 3464A21 or 2748A47). The drill tap is a close fit in the hole so the tapping operation is straight.

If not, I have a working copy of the software- you're welcome to pop by with the VCI/bike/laptop & we can get you going.

Sometimes you can soak them in Knock'er Loose and then scrape with a plastic blade.
Sometimes it's easy, sometimes you wanna buy a lathe so you can machine that stuff off  .

If they have the VCI that is married to that bike, it can be made to work. Is it the SE Pro Supertuner, or the SE Street Tuner?
You can go into file manager, and edit the last update time, to over ride the "check for updates".

Yes it's the SEProST that is married to the bike when he bought it new. I'll try what you suggested and see if my software will work. I haven't bought the bike yet so have some time to see if I should just plan on budgeting for a tune license. Thanks

Has anyone got a magic formula for a liquid that can dissolve this base gasket besides harsh mechanical removal with the risk of damaging the cylinder base gasket surface?

Wish they had one for the M8 Softail.

Is the SEPST pretty much useless now?Why I ask: looking at a low mile 2012 Ultra, owner purchased and had bike flashed with a SEPST when it was new in 2012. Only thing they changed was the air cleaner. I would want to do a non cat headpipe and slip-ons if I buy it. I have the SEPST software on a Win7 PC but when I open it it says flash programming disabled, check for updates, then says update failed. I'm guessing I will just be better off buying a tune license and keeping my PowerVision and using it. I hope it was ok to ask here, I haven't kept up with things since they switched to epa friendly tunes on the HD tuners. 

I have 2 sets of dual plugged heads. After 20 years of using them hard, they are pretty much used up. Both sets have small cracks in the return oil gallies that allow oil to just sleep through to the outside of the heads. I decided they just aren't worth sinking more money into them. So I sourced a new set of heads and decided to keep these stock.

I did have to switch up my starting routine a bit. These heads like to have more fuel during startup. That's the biggest difference. A few more twists of the throttle before a couple primer kicks w/ key off.

The big difference is in fuel economy. I used to get 62mpg on the highway tank after tank. With the stock heads, I'm closer to 50mpg.
