Dead Revs Explained [alt_text]( [bikebandit.com main hero] As your bike cranks up and gets ready for that engine to howl, there’s always a few dead revs before ignition. Whether you’re driving a modern cruiser or a classic dirt bike, this delayed start can seem unusual or concerning. If you’re concerned about your ignition timing and think dead revs are the culprit, here’s a complete explanation of why your motorcycle has these programmed into your electronic or other ignition type and why you need them. Difference Between No Crank and No Start First, there’s a crucial explanation we need to tackle. There’s a world of a difference between your bike not cranking and your bike not starting. The initial sound you hear when you hit that starter button is the cranking sound. Whether you have an electric ignition or not, your bike is designed to go through a few cranks before it gets the green light to fire it up. A bike that doesn’t crank needs a whole new set of troubleshooting compared to not starting. When a bike doesn’t start, you won’t even hear that signature cranking sound. If your engine doesn’t rev, it means there’s an issue with a completely different area of your ignition. The important thing to remember is that a few dead revs aren’t a bad thing, and are actually a safety feature built into most bikes. What Are Dead Revs? If you’re like us, you sometimes wish your e-start bike would just fire up already. You bought a modern, fancy bike to enjoy hassle-free starting, yet it always takes a few tries to get going. Thankfully, there’s nothing to be concerned. These false starts, or cranks with no kick, are called dead revs and are a normal part of your bike’s starting system. For most modern motorcycles, an electronic ignition is pre-programmed to include a few dead revs immediately after you hit the starter button. Some bikes use them as a safety feature, while others use them as a way to determine the proper moment to add fuel to a particular cylinder. A major reason that dead revs are so essential as a safety feature is to avoid kickback. At the top of the compression stroke, your engine has a lot of fuel and air and can sometimes crank the wrong direction. On older bikes, kickback was a painful, frustrating experience, but on newer bikes it can be deadly. Instead, dead revs are programmed to allow the ECU to ensure that the crankshaft and camshaft are in the correct positions related to each other and everything’s spinning in the right direction. A few dead revs allow all your sensors to work their magic and give your fuel injection system permission to start your engine. This whole system is rapidly making your lubricating starter Bendix gear outdated. Your Bendix is used with your starter shaft to physically push the starter gear onto the same plane as your flywheel. The major differential in terms of speed between these two parts make this a high-stress point. Modern solutions use a one-way clutch on the flywheel instead, while is a much smoother transition than conventional Bendix gears.
