motorcycle fuel injection problems

There are a number of ways of applying a custom map to an ECU — well, three main ways. Carburetor vs Fuel Injection Engine. RB Racing is the only motorcycle fuel injection company that designs and manufactures its own electronic controls, software, throttle bodies and wiring harnesses Motorcycle Fuel Injection Note: As of June 2018 these are no longer being shipped or manufactured by RB Racing. BMW G310 R is coming, but does it matter? Taking The Mystery Out Of Fuel Injection. For example, I tuned my Triumph Scrambler’s ECU using TuneECU (software you can buy for an Android phone or a Windows PC) and a programming cable I got on Amazon. They will reset the AFV, CMP, IAT, and check your milla seconds pulse width. Hence after learning both the advantage and disadvantages of carburetor vs fuel injection system you can see both of them have different advancement and weaknesses. The fuel pressure regulator is located on the back of the fuel injection rail (not easy to access) and its depression is collected at the intake manifold for cylinder #4. Turning this screw clockwise will reduce the amount of air entering the carburetor, and will, therefore, richen the mixture (refer to a shop manual for correct settings). When figuring out the mixture, the ECU doesn’t just use the lambda sensor. Hello good guys, I’m in a car team and in a few days we’ll start with engine bench sessions. Just like in open-loop mode, the ECU uses a bunch of other inputs as well to determine optimal mixture. Motorcycle fuel injection, Kevin Cameron explains in this video, uses throttle angle, engine rpm, and a stored map to determine the correct air-fuel mixture. That's what I'd do for you. I filled it with gas the other day and now it won't start. Start the engine when cold and let it run at idle for 5 – 10 seconds. Lots of oxygen means the fuel got fully burnt with oxygen to spare (too lean); no oxygen means that there wasn’t enough oxygen to burn all the fuel (too rich). In most cases, a high-output fuel pump is needed to meet the demands of the system. If the computer observes the same conditions for a second to a few seconds, it thinks “hey, things seem stable enough” and it switches from open-loop to closed-loop mode. What advice would you give us to know which point is going to be the most optimal in the range of action of the closeloop. Opt-in alpha test for a new Stacks editor. I don't know exactly when it started coming on. Unable to Open Injector Again, this can sometimes be perceived as a jarring transition — it depends on how “smooth” the computer’s tuning is. Quick conversions between Imperial and metric units for power, torque, and mileage. How to Fix Fuel Injector Problems. Harley-Davidson Fuel Injection basics It is a sad day in Hogville. I ride an '06 Streetbob with a stage 1 upgrade and recently have had a problem with my rear cylinder. In closed loop mode, the ECU will use the input from the lambda sensor in the exhaust to determine the correct amount of fuel to inject to the engine. These are an interface between the oxygen sensors in the exhaust and the ECU. In a standard configured motorcycle with an ECU, they switch from closed-loop to open-loop operation automatically. there is a thread about it on korider.com | Hyosung Motorcycle Owners Forum - … Motorcycle Fuel Injection (Fi) System Explained. Related. This means that you might experience things like: These problems can be resolved by modifying the fuel map, and sometimes the sensors. small-motorcycle fuel injection systems. Q: I have a 1985 BMW K100RS, which uses L-Jet Bosch fuel injection. fuel pump 83 1100 GPZ. Because the lambda sensor is an organic device, it can’t give as fast feedback as a digital device would. Opt-in alpha test for a new Stacks editor. But most importantly: stay safe, and stay alive. I have installed a new suction screen on the fuel pump. I have plenty of spark, but no fuel getting to the rear cylinder. But now more and more two wheeler companies are looking into fuel injection as an option in their bikes simply because it is the new tech that has come up. see reply by Mfolks about Larry Cavanaugh Racing. In a nutshell, closed loop is where the engine operates with a feedback loop. I haven't had much luck in the past using the search feature here, so I do google searches of topics from this site only: The too lean air/fuel mixture on the standard bike will make idle and low speed running weak, and the throttle action will be horribly on/off like. In turn, when fuel additives aren't sprayed into the intake manifold, they can leave a residue on the injectors that burns and becomes crusty. Developing fuel injection systems for smaller motorcycles presents several problems not seen in automobile systems, and considerably more demanding limitations than those applying to systems for large-displacement motorcycles. The difference isn’t just in the values, either — they also have different levels of granularity. This can be done by adding a fuel system cleaner to your vehicle’s fuel tank and working it through the system. This week it’s Kawasaki's introduction of the first motorcycle fuel-injection system. 4. Anyone who installs a fuel controller into a fuel-injected motorcycle may come across the terms “open-loop” and “closed-loop” mode. Here are ways to fix the problem: ... Honda Philippines, Inc. has reminded riders not to be complacent when using their motorcycle as means of solo transport during... Jun 25, 2020. Hopefully this was a clear enough explanation of open loop vs closed-loop modes of fuel injection. This is the engine switching to closed-loop mode, or switching between odes because it’s confused. I ride an '06 Streetbob with a stage 1 upgrade and recently have had a problem with my rear cylinder. Engine recently overhauled and runs beautifully. Motorcycle engines are still basically using computer controlled carburetors mounted to individual intake runners. Hence after learning both the advantage and disadvantages of carburetor vs fuel injection system you can see both of them have different advancement and weaknesses. If I put the software back to standard (O2 sensor on) the issue disapears. What fuel injection does makes what carburetors do seem like little more than guesswork Electronic fuel injection (EFI) consists of throttle bodies that take the place of the carburetors, the ECU computer and special sensors. But considering everything fuel injection is the best solution for most of the kind of motorcycles. Motorcycle fuel injection, Kevin Cameron explains in this video, uses throttle angle, engine rpm, and a stored map to determine the correct air-fuel mixture. Either way, you’ll want to take care of the problem soon or the engine will be susceptible to overheating or other problems that occur when the proper air/fuel … Discussion in 'Dyna Models' started by ladge99, Jul 25, 2011. Lambda sensors are an electrochemical fuel cell with a zirconia element inside (yes, the same zirconia, a.k.a. Workshops can always do this, but sometimes users can do it too. Once we have the fuel base map set to lambda 1 and the advance calibrated to achieve that linearity, we want to see the possibility of implementing the digital lambda closeloop. If the engine does not get enough fuel sprayed into due to a clogged injector, then the engine will misfire as you drive. However, we were able to overcome these problems and develop a system Fuel Injection problems. This is how often fuel is combusted in your motorcycle engine for an average given engine speed in RPM: (…or some other number if you have a triple or a behemoth of a six-cylinder motorcycle. If the motorcycle is in working order, the idle level does usually not change from the standard setting, so an unusually high or low idle is a warning that something may be wrong. In the late 1970’s Kawasaki Z1000G-1 Classic was a … I bought a Honda 1980 XL500S scrambler a few months ago and absolutely love this old bike. Motorcycle Fuel Injection Handbook Paperback: 159 pages Dimensions (in inches): 0.38 x 10.60 x 8.22 Publisher: MBI Publishing (July 1, 2004) ISBN: 076031635X I absolutely love books like the Motorcycle Fuel Injection Handbook! I have also replaced the plugs. I’ll try to explain it simply. I took the fuel pump relay out and it bench-tested good. Good luck The ECU computer makes fuel calculations based on inputs from sensors on the engine and at the throttle bodies. Thanks for the great article! I don’t want to lead you astray and so I don’t want to guess haphazardly. This week it’s Kawasaki's introduction of the first motorcycle fuel-injection system. Most modern motorcycles come equipped with a fuel injection system which requires fuel to be delivered at high pressure. So what is the concept of Fuel Injection? Notes from an interview with Guillermo Cornejo of Riders Share. Rear injector replaced about 8k ago (took the HD mech 5 hours to figure out the injector was bad, another 3 hrs on the dyno to tune afterward). The first way is to reprogram the motorcycle’s ECU. Sometimes, motorcycle owners just eliminate the sensors. The objective is to make the engine’s torque response as linear as possible, since it is for a driverless prototype. 2003 Harley Classic, fuel injected. If you then accelerate, the engine will be told “yo! 6 0 0. 3 Posts . You have hesitation as you accelerate hard, usually in the low-mid RPM range: This is the computer being hesitant to enter open-loop mode. Hi there Nuno, thank you! Carburetor vs Fuel Injection Engine. These are the parameters to take into account: ECT lockout (ºC), Timer Lockout (s), RPM Lockout High, RPM Lockout Low, MAP Lockout > (kPa), FTrim Limit -/+ (%), Gain Control. zirconium dioxide, used in that fake diamond you bought your ex, but in powder form in a battery… so romantic) that reacts to oxygen. If there’s one thing I want you to take away, it’s this: closed loop is about saving fuel and being environmental, and open loop is about performance and responsiveness. Developing fuel injection systems for smaller motorcycles presents several problems not seen in automobile systems, and considerably more demanding limitations than those applying to systems for large-displacement motorcycles. It can be a fraction of a second or a few seconds.​. But it seems that you have already narrowed it down to the tuning. Related. Diagnosing dead or clogged fuel injectors is difficult because it acts the same than a bad coil, dead spark plug, broken spark plug wires and or electrical problem. This way the ECU is able to adjust the air/fuel ratio based on the actual result of the combustion. Most fuel injected engines utilize a cold start circuit inorder to maintain idle when the engine is cold. H ... Hi Folks-My name is Kent and I have a motorcycle restoration business for bikes pre-1980. They read articles about fuel-injection, but they never see anything about how fuel-injection actually works. You’re keeping constant speed on a flat surface and the throttle is nearly closed: The motorcycle lurches and jerks. Motorcycles switch to closed-loop mode when they’re basically idling. Motorcycle buyers guides, reviews, market analysis, gear, and much more. The result of eliminating the O2 sensors is that the motorcycle is always in open loop mode. Lots of oxygen makes the lambda sensor’s fuel cell put out low voltage (0.2V), and little to no oxygen makes it put out higher voltage (0.8V). I have a 2001 road king. (Or try other maps…). You can remove closed loop mode if you want. Even the most knowledgeable technicians weren’t born that way and started out learning the basics. Buying the 12 port injector and the ECU may not solve the problems without having some sort of fuel injection tuner like the JD or PC. Below I’ll explain this in more detail, including when a motorcycle is in closed loop vs open loop, and how it affects the way you ride. Suzuki recommends Chevron injector cleaner with Techron additive. In motorcycles (and cars), the “measuring element” is usually an oxygen sensor. For more fuel injection topics try searching for replies by Mfolks. The too lean air/fuel mixture on the standard bike will make idle and low speed running weak, and the throttle action will be horribly on/off like. Your vehicle will struggle to accelerate or there will be a pause after you step on the gas pedal.. Rent a bike from other riders with these special deals! There are a number of common problems that can lead to what people describe as “poor fuelling” and long for the days before emissions restrictions, and possibly before fuel injection. mpsracing. A dirty fuel injector can cause fuel line problems such as misfiring, hard starting, stalling and hesitation. I have lived in a dozen countries, speak almost as many languages, can deadlift a motorcycle, make a mean cappuccino, and do one great card trick. There's a big likelihood that your fuel injectors are clogged if you see most of these problems happening in your vehicle. While a few carburetor-equipped bikes are still on the market, the vast majority of street bikes are now equipped with some form of electronic fuel injection, which despite the complication it adds, is both a better way to go, and undeniably here to stay, protests from the Luddites … Setting the idle level. But you’d use a lot more petrol and you’d never pass ever-tightening emissions standards. A quick peek into the motorcycle's fuel tank, specifically at the tank's inner metal lining, can reveal problems that may be hidden beneath an otherwise perfect exterior. The mighty Harley is slowly loosing its carburetor. The fuel pressure regulator will keep a constant pressure into the fuel injector rail. Fuel Injection problems. What do these mean? Harley-Davidson Fuel Injection basics It is a sad day in Hogville. This will result in higher fuel consumption and emissions. Have replaced fuel pump twice and now its going out again. One of the most common problems is over-aggressively switching to closed-loop mode. Just like in closed-loop mode, the ECU uses information from a whole bunch of sensors, including sensors reading. It is virtually impossible for a motorcycle technician to accurately analyze the condition of a motorcycles fuel injectors while they are still on a motorcycle.

Gasoline Direct Injection uses fuel injectors to spray fuel … Even the most knowledgeable technicians weren’t born that way and started out learning the basics. Kawasaki Mule 4010 Fuel injection problem. The engine is that of a Honda cbr 600rr and we will only reach a maximum of 9000 rpm since the objective at the moment is stability and we will move through low torques, Your email address will not be published. One of the most common problems is over-aggressively switching to closed-loop mode. Specifically, I’ll be focusing on fuel injected engine maintenance, which really is 99% the same as maintenance for a carbureted motorcycle. If you like what you read here, and you’re a fraction as obsessed as I am, you might like to know when I’ve published more. I love learning and sharing what others might find useful. Fuel injectors are considered to be dirty when the hydrocarbons and additives which all forms part of today’s fuels, together with engine gunk and carbon, cause the injectors to become restricted. In open loop mode, it doesn’t! The way the computer thinks about this is its fuel map (see the picture above). There's a big likelihood that your fuel injectors are clogged if you see most of these problems happening in your vehicle. Does this make sense? In open-loop mode, the engine relies mostly on a fuel map to understand how much fuel to add to the engine. 4. That diagram is a simplified representation of how closed and open loop systems work. The simplest and most common kind of fuel map relies on just two things — throttle position and engine RPM. BMW motorcycle engines from the old airheads through the oilheads, hexheads, metalheads, revheads, and jugheads.

Well, I am. Diagnosing a clogged injector is not always easy because it acts the same than a bad coil, a broken spark plug wire or a bad spark plug. Repair or replace frayed fuel injection wiring harness? A third way is to install an O2 sensor modulator. As motorcycles have become more complicated diagnosing problems has … the accelerator is on!” and switch to open-loop mode, relying on the fuel map instead. Electronic Fuel Injection (EFI) is now standard equipment on almost every street motorcycle manufactured around the world. Fuel-injected engines — basically, most motorcycles since the mid-2000s (and almost all that I buy) that have sensors and fuel controllers. Symptoms of a bad injector or injectors can include difficult or impossible cold or warm starting, irregular idle, lack of power, poor fuel economy, missing, high emissions and external fuel leakage. They take the normal output and give the ECU an input that means “Yo, actually… richen it up a little.” A couple of popular ones are the Booster Plug and the Rapid Bike Easy. This usually results in replacement. The rapid and repetitive movements of fuel injectors cause a friction that makes them very hot. The sensor in question is a lambda sensor, also known as an oxygen sensor or air/fuel ratio mixture sensor. A sensor closes the loop. It's important to check the injector internal electrical coil. If you are experiencing any of these symptoms, the fuel injectors may be causing the problems. Discussion in 'Dyna Models' started by ladge99, Jul 25, 2011. Really, best fix is to take it in and have the TPS zero function reset. When conditions stabilise, for example, if the throttle is returned to a low position and the RPM is constant, then the ECU will switch back to closed-loop mode. So even with 100 firing events a second, you’d get far fewer feedback points a second — but still enough for your computer to operate as lean as possible. Required fields are marked *. $69.95 drop in injector using NEW genuine Bosch cores. Airhead, Hexhead, Oilhead… What are the BMW motorcycle engines? The same system is used on the first generations of fuel injected motorcycle engines. The small controlled fuel enrichment with the BoosterPlug will solve the common fuel injection problems and make your motorcycle … I do mostly Trials,Enduros and Motocross bikes but lately I have been trying a new venture-Bobbers.
