Installing S&S Cycle Tappet Cuffs on a M8 Engine

Arr, M8y!

S&S Cycle continues rolling out new Milwaukee-Eight upgrades all the time. It’s almost as if they’re in the business of making the most of V-twin powerplants or some such. One of their newest additions to their Milwaukee-Eight parts family is a new tappet cuff.
The new M8 engines are proving to be a stout motor that responds well to hop ups – but one of the components some aren’t too thrilled with is the plastic tappet guides that could potentially let tappets twist under high RPM and when coupled with high lift cams. S&S developed a clean solution with its new machined aluminum and hard anodized Tappet Cuffs. Here’s how they install to your bike.

Designed to stabilize tappets in high performance M8 engines, S&S Cycle says these should pair well with any cam change and are a must-have for Stage 2 and above builds.

ABOUT S&S Cycle®

What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George J. Smith had to build his own parts to make his motorcycle faster. Now the company he founded manufactures the most pretigious line of "go fast" v-twin engine parts in the world. The company was started in the basement of his home in Blue Island IL in 1958, and moved to Viola, WI in 1969. In 2004 an additional facility was opened in La Crosse, WI.
