Just installed an Athena 70 kit in my 2003 BWS and I'm having difficulty getting the Squish to Athena specs of .93 mm. I can get the Squish to 1.16 mm without a base or head gasket. I have considered having the cylinder head machined but as a last resort. Any thoughts on running without a base or cylinder head gasket? Thanks from a Newb.

You could just use copper spray. What type of cylinder head gasket does it use? What do the transfer ports line up like?

I had the same problem with the athena kit . As long as you get squish down to below 1.25 you will have plenty of power . I run copper spray only to get down to .92 Squish is important But so is how the transfer line up so you max them out for flow in and out of the cylinder. Here is where the Transfers are maxed out by having the piston at BDC being even with Transfers and below exhaust port on my Athena .

How far is the piston edge from the top of the cylinder? You could have the top of the cylinder machined also if the piston wound stick out of the top. I also have a head that was machined by someone on here that sits inside the cylinder to reduce squish.
I used copper spray gasket on my base no gasket.

Thanks Zino, went with copper spray for the cylinder head and Permatex Grey for the base gasket - so far so good. A couple more heat cycles, a re-torque and fingers crossed.

Enjoy your New Kit The Athena spins up quick and is real torqee I would suggest getting a temp gauge so you can protect your investment. Just watch for temp spikes and Wide Open Jetting should settle in below 350 degrees .
If you are just putting on a kit lowering the needle one notch rich and a slight up jet of 5% is usually needed If you add a pipe another notch up on jetting is needed . Stay with the stock Airbox it is the easiest to tune for and keep your kit at safe temps .
