of found the on ebay and amazon
It says it's for EVOs... but if you say it'd fit, great.
So... could that be the cause of my problem? the breather and the hole are worn so they don't seal?
I guess the reed gear would do a better job than the plastic gear anyway...

 

i know they at S&S say its for an Evo - we have used them in shovels BUT you might have to close the primary from the engine and add oil to the primary one cup 16 OZ type of thing - some work with a ripped breather like you have and some dont -- just so you know

 

no problem closing the primary
I guess the standard size gear would work? the bigger one if for cases that have been machined?

At some point I wanted to add a cam as well... and you were suggesting Andrews AB with longer exhaust duration (80" shovel, oem pistons, new 6 speed transmission RevTech gearset, 0.86:1 6th gear, CV carb, no voes)... but maybe I would wait a little and see how I like teh current configuration... or I can do that later and replace the cam bearing and check how things are down there... ?

 

Turns out my cam is shot too...so getting cam and rollers
