First, let's see what's inside the box.







This new piston seems very light, and only has grooves for one compression ring plus one set of oil rings. The stock piston uses two compression rings (as we'll see later). Not sure if this is any issue for concern. "Back in the day" seems we ran one compression ring in lots of stuff. But what do I know.

I was going to weigh all this stuff (for Machtig), but I didn't have a gram scale, and well, I got antsy to install it. So, somebody else do that step when they get theirs (hint...hint....Emmerson Bigguns). We'd all like to compare the weight of the stock piston/ring/wristpin to the Athena version of same. You can add the results right into this thread....that's what's its for.

The Athena kit comes with a completely new casted aluminum cylinder. It is not a sleeve kit for your original stock cylinder. You swap out your cylinder assembly entirely. The nice thing about that is...if I don't like it, I could swap back to my stock assembly later.

Well, it was a good thought.

The Athena kit also comes with a very complete set of gaskets & washers, plus a custom electronic fuel programmer, which is needed for the larger motor (if you don't have another similar capable unit already). I won't be needing this item, as I have also purchased the much more sophisticated Dynojet Power Commander V fuel programmer, and the AutoTune unit. I'll get into those items later. For now, let's start wrenching.


Where do we begin? I guess right here:



Remove your seat, tank, & sidecovers. Then, remove the pipe (this is my FMF Q4 +Powerbomb Header). I love this thing, because it really works well, sounds sweet, and is SUPER lightweight compared to the stock pipe.



Whether stock or aftermarket pipe, make sure you carefully remove this thick washer from your exhaust port on the head.





Next up, the radiator removal...
