Picking the right clutch for a Briggs & Stratton LO206? Honestly, it's one of those decisions that'll make or break your lap times. After messing around with a bunch of different setups and watching what the fast guys do, pretty much everyone agrees—the Bully Slide-Out Clutch is the go-to for most tracks and skill levels. But hey, it really depends on your track and how much you weigh. The Bully Slide-Out? It's basically the gold standard for LO206. What makes it so good is you can adjust when it grabs, and it just handles the engine's power band better. Unlike those old disc clutches that slam into gear, the Bully uses this slide-out thing that's way smoother. You get better traction coming out of corners—less shock to the drivetrain, and you're back on the gas quicker. It's the clutch they use at the Briggs & Stratton 206 World Championships, so yeah, it's legit. For a Bully on a LO206, you want it to grab between 3,200 and 3,500 RPM. Get this wrong and you're screwed. Too early—like under 3,000—and the engine bogs down coming out of turns. Too late—over 3,600—and you lose all your momentum, plus the clutch slips like crazy and burns up. You tune it by swapping springs and weights inside the hub. For a stock LO206, start with "Blue" or "Black" springs and the standard weights. And for god's sake, use a tachometer to check where it's actually engaging. Oh man, this argument never ends. The Hilliard Flame is the Bully's main rival. The big difference? How they work. The Hilliard uses these disc shoes with a flame pattern—it's a centrifugal thing. The Bully slides out. In real track testing, the Bully just feels smoother. It's way more forgiving if you're a newer driver. The Hilliard can be more aggressive, and some experienced guys love it on high-grip tracks. But honestly, the Bully's adjustability and how long it lasts makes it the better choice for serious racing. The Hilliard's cheaper, but the Bully's the refined option. Depends on the track, obviously. But a solid starting point with a Bully is a 15-tooth front sprocket and a 60-tooth rear (15/60). That works for most medium tracks. If you're on a tight, twisty track, try 14/61 for better acceleration. For big, fast tracks, go 16/59 to get more top speed. The clutch doesn't change your gear ratio—it just changes how the power hits. Tune your gearing for the track first, then adjust the clutch to match. Check it every race weekend. Rebuild it every 10 to 15 hours of running. You'll know it's time when it slips under full throttle, the engagement RPM gets all weird, or you can see wear on the shoes and drum. A rebuild kit has new springs, weights, and sometimes a drum. Don't skip maintenance—it'll kill your performance and could mess up your crankshaft. Clean the drum with brake cleaner to get rid of that glaze buildup. You can, but don't expect to be competitive. Disc clutches like the Noram GE grab hard and can mess up your chassis or spin the tires. The LO206 doesn't have the top-end power to fix a bad launch. Stick with a slide-out clutch. Most LO206 clutches are dry—no oil. The Bully and Hilliard are designed to run dry. Don't lube the drum or shoes. Some clutches have sealed bearings that need a tiny bit of grease, but the friction surfaces should stay dry. Usually worn shoes, a glazed drum, or bad spring tension. Check your engagement RPM. If it's too low, it'll slip. Look at the drum—if it's all shiny and polished, lightly sand it to bring back friction. If the shoes are worn down to the rivets, replace them now. You gotta break it in. Take it easy for 10-15 laps, no full-throttle launches. Let the shoes seat against the drum. After that, re-check the engagement RPM because it might change. Never hammer a new clutch right out of the box.What is the best clutch for the LO206
