Hello KTMATVHQ!
I thought I'd contribute my first technical post with a flowbench test and pics on the 09 KTM SX
it's a very impressive head to say the least, in stock form,... but peeping into the head I can tell these heads true potential is going to real good after a port and flow job...
Oh, and after using my 5MHz ultrasonic thickness meter I probed around the intake side... looks to be about 0.125" port wall to jacket thickness on the sides and roof.... concentration around the guide boss, short side raius roll-back, adjusting cross-sectional with a bit of unshrouding- BAMMM!
Flowtest graph forthcoming ...
