When I got mine apart it had gooey grease all over it, including the piston seal. Mine was shooting somewhere between 850 and 1200fps out of the box!!
Here's a look at the piston seal:

That black crud is all grease, I actually cleaned my stock seal up and it is a perfect cream color, not black like in the picture...that's some gooey stuff! I saved my stock seal/spring/guide in case I ever need a spare. The stock spring is a bit loose on the rear spring guide, but not by much, unfortunately there's no tophat like the Maccari kit has.
Happy that yours finally came in and that you got a good deal, they are awsome guns and well worth the money spent:) Bet yours will shoot real nice with the "Gene tune" on it and all of that gunk cleaned out of it. Mine is my favorite springer of all time.....oh geez, I used "favorite" and "springer" in the same sentence, guess Kirby is rubbing off on me
