Just how big do you want to take you Milwaukee Eight? If you want to impress your mate at the end of the bar, you can’t go high enough … but then they’re not likely to ask you to prove it.
You can tell them, with confidence, that having slotted an S&S 4¼ big bore kit onto your 107-inch Milwaukee Eight you’ve taken it up to 124ci – over two litres – or your 114 to 128ci/2,100cc and they can look it up and satisfy themselves … always assuming you’ve got an air cleaner and pipes that will let that much air through. And if they ask, no you didn’t need to bore the cases: it bolted straight on.
Yes, of course you got it set up: do they think you’re going to throw a grand at a pair of barrels and pistons and assume that the closed loop injection will take care of the rest? Some people!
Kits include forged pistons, piston rings, wrist pins, clips, head and base gaskets and the cylinders in wrinkle black or wrinkle black with highlighted fins.
