18-24 Softail, 17-24 Touring, (except 23-24 FLHXSE, 23-24 FLTRXSE, 24 FLHX, 24 FLTRX, 24 FLTRXSTSE), 17-24 Trike
Nota: With stock valve springs
Milwaukee 8 bikes are available in both 107 and 114 cubic inch engine sizes. With high efficiency four-valve heads, M8 engines show great potential for performance gains especially with new design Andrews M8 series camshafts.
Keep in mind, cam timing specs for four valve heads look very different from camshafts designed for two valve applications. Engines with four valve heads have much greater flow efficiency so cam timing durations are a lot shorter.
