View Full Version : What's this catalog jibberish?

I'm starting to think about my conversion and saw the 1200 jugs in the SE catalog with the following description:

Except for relieving the combustion chamber for correct
compression ratio, these cylinders make the conversion
to 1200cc a bolt-on operation. No cylinder head
machining required when used with Screamin’ Eagle
Cylinder Heads, or 883/1200 Conversion

Does this mean if you use these jugs and want to keep the stock heads you MUST do head work? If this was answered already perhaps someone can point me to the thread. Thanks.

Yes, you must relieve the combustion chamber to get the correct compression ratio if you use factory 1200 pistons.

If you use 883/1200 conversion pistons, no head wrok required.

I just finished my bike today. Used the parts you are talking about. If you don't do the heads you use the dished pistons. If you use the dished and want to improve the heads later you'll be replacing the pistons again.
