tl dr: Corrosion (once cleaned) is not a huge issue. It is just typical corrosion on the battery terminal. See this image: (NOTE: This is a 6V battery, but the same principles apply.) The blueish color you see is hydrated copper sulfate. When acid vapors escape from the battery, it can cause a reaction with any copper which may be in the terminal. The ...

Turn the key in the ignition to 'On' Hold the clutch lever Engage first or second gear Let the motorcycle gain speed (either go downhill or push start) Let go of the clutch lever. The motorcycle should sputter to life

From personal experience, I'd replaced ALOT of these working at the dealership. It wasn't just the accords either, it was quite a few Honda and Acuras that used the same design and power delivery system. The most common issues I saw out of probably close to 100+ failures of these was: Ground strap on the starter becoming corroded. Bad ground to engine ...

This sounds like a problem with the coolant temperature sensor. Don't worry - replacement is cheap and can be done easily by yourself or a friend who worked on cars before. Cause Cold engines need more fuel to start than warm engines. This is due to the fact that a part of the vaporized fuel condenses at the cold cylinder wall inside each cylinder. This ...

Repeated clicking is a result of not enough power making it to the starter. Your battery either has a bad connection, or is too weak to turn the starter motor. Battery Connection Your problem may be entirely due to a bad connection. Starters draw a lot of amps, and batteries are weaker in cold temperatures. I'd start by fully exposing the terminals. You ...

Something to keep in mind is that the time an engine takes a great deal of its wear is cold starts. The oil isn't up to temperature yet, so parts are not separated as they should be and you get more wear. If you do this very frequently, like going from red light to red light, you're probably doing more harm than good. Also, if your car does not start as ...

I've a 93 and have had what sounds like the same problem, that is the ignition turns on but when the key is turned further to start the engine it does not always crank the engine. In my case it was the ignition switch and being one not to through money away I took it all apart and cleaned the switch contacts and it's been fine for the past four/five years. ...

Your problem is caused by decompression valve problem in 650 engines prior June 2012. Only way to get rid of it permanently is to replace decompression valve, which fortunately is not a huge job. BMW bulletin about the issue: http://www.gravesurrounds.com/bike/hotstart.pdf Chances of having hot start problems due decompression valve are higher when your ...

It could also be the Crank Position Sensor. It is mounted on the flywheel cover and if it gets contaminated with dust from the clutch it can stop the engine from starting. It confuses the average guy as it looks like either a fuel or ignition problem. It is held in position with two bolts. Might be awkward to get to. Hope this helps.

This is called "run on" of the starter. It doesn't cause a huge issue if it doesn't happen too much or for too long, but basically the Bendix stays engaged in the flywheel ring gear an is being then driven by the engine. To further explain, the Bendix (or pinion drive mechanism) is the part on the end of the starter armature which engages the flywheel (or ...

Two things about this bike if it is OEM It has two sets of coils. It has two sets of points. If you take the right side cover off the motor where the crank is, you can see if the points have been swapped out with signal generators, a common mod for this bike. One coil fires for cylinder 1 and 4, the other fires for cylinder 2 and 3. IMO you have a bad ...

This could be caused by multiple things, the most likely case would be a bad battery in need of replacement. However before coming to that conclusion there are a few things which can be checked. Make sure your battery terminals are in good working order and are not grounding out any where make sure they are insulated and not cracked and touching metal. ...

I recommend you carry out the following steps: Have the starter relay tested. From the description provided (old starter was clicking) this may actually be fine but it is so easy to verify that it works it would be silly to not rule this out as the source of the problem. After locating the starter relay, have someone turn the key in the ignition to start ...

It sounds like your clutch master cylinder is initially letting fluid past the piston seals. Pumping the clutch pedal sounds like it gets the piston sealing again so that the clutch starts to work. I am presuming that the clutch and brake both share the same reservoir and that you are not loosing fluid and not having to keep filling it up. Is that correct? ...

Voltage drop the ground side pin 4 with the car running. I'd suspect a poor ground is the cause. You can also scope the power side by removing the fuse and putting a wire loop in place. Connect a low amp probe. Since the fuse is rated @ 20A you should expect to see 8-10A if it's drawing more amps than that suspect a short to ground or a bad ground or ...

I'd suspect that it is causing extra wear on the starter motor and flywheel (where the starter motor engages). Considering the start isn't in motion at any point other than starting the car, and there's no contact between it and the flywheel unless you are running the starter, you are causing more wear. Depending on the cost of replacing those parts, it ...

Your carbs are clogged with varnish and bad gas The remnants of gas that has evaporated are a gummy hard varnish inside of your carburetors. You have a bit of work to do. You need to completely disassemble the carburetors and thoroughly clean all of the nooks, crannies, jets, fuel galley's and air galley's in order to get your bike back in working order. ...

I have also prefilled my oil filters when I can. There is a notable difference in the amount of time it takes for the gauge to register when comparing prefilled to not prefilled. The difference is still fairly small though, I guess about 2-3 seconds. Although it seems like a life time while you watch the gauge. I believe this is insignificant though. If you ...

There are two power systems on all electric cars (fully electric and hybrids alike). This is in conjunction with the much higher voltage battery packs which normally power the electric motors. The reason for this extra power system is to power things like lights, electronics, and HVAC systems (to name a few). Most hybrid vehicles (and never a fully electric ...

Pretty Common Problem with the Duke 390 This is a very common issue with the KTM 390. There are dozens of posts regarding customers who are experiencing the same exact issue. Additionally, there are a few YouTube video's that show the problem happening pretty consistently. The various proposed issues related by customers seem to revolve around these ...

One possible cause might be the 16-year old, slightly mechanically stretched timing chain that gets the "right" amount of additional elongation from the warm engine that puts the engine timing and more specifically the ignition timing out. Another component that could lead to problems with the timing chain is a faulty tensioner.

Ice Probably the most common problem that people have is when their car is parked in a moist environment below degrees, resulting in ice forming on some or all of the windows. To resolve this problem, see this answer. Battery Another problem that is quite common (this happened to me recently), is if you have a car with a car battery that is in poor ...

The main problem would be the battery, as already pointed out. In low temperatures batteries tend to lose power, and for batteries near the end of their lifetime this means that you won't have enough current to turn the engine. Another problem would be the wrong oil chosen for the engine. Oils have grades based on their viscosity in certain temperatures - ...

Many times you can start a motorcycle with a low battery This answer has a push start method You can also coast down a hill and let out the clutch with the ignition 'on' and the start switch set to 'on' Use jumper cables and get a charge from a car battery. You can use the jumper cables and allow the car to just idle. You don't want to charge your ...

Most Kick Starters Have a Relative Position They Need To Be In What I mean by this is, you can get your kickstarter into the system and mount it up bet if you do not put the shaft in at the correct degree it won't operate properly. Think of cam timing. Perhaps a poor analogy but.... Look at this parts diagram On shaft 9 and gear 11 you need to have them ...

Not familiar with your vehicle/engine specifically, but familiar with carbed engines in general. I would think the #1 thing to look at would be the choke. Pumping before starting a carb vehicle is normal. It gives it a squirt of fuel and sets the choke. The low RPM indicates that the high idle is not set, which likely means the choke is not set also. ...

This is rather specific to the hazards of car ownership in West Africa, so I'm not surprised no-one has suggested this! After using an improvised variant of this method to confirm that it was indeed an electrical problem with no power reaching the spark plug wires, I had a closer look at my fuse box, and specifically the "EFI" (fuel injection sytem) fuse. ...

It sounds like your carb(s) are plugged and need cleaned. If the fuel in the carbs has ethanol in it, the carbs are going to be caked with crap. The floats could be ruined. There are a lot of things going on. Getting the carbs rebuilt or at the very least cleaned up, is going to be a must. All of the symptoms you saying are pointing to carb issues.

Sounds more like a problem with the ignition switch, possibly some kind of interference with the steering wheel lock. Do you usually park on the street with your wheels turned? If so, maybe try to make sure your wheels are pointed straight before you shut off the car. This should take the binding out of the steering linkage and put less stress on the ...

Two Possibilities Off the top of my head I would look at the following: The clutch start switch - a broken wire or switch will prevent you from starting the bike. It disables the starter relay by grounding it out unless you pull in the clutch. Side Stand Switch - See if the side stand switch hits properly on your kick stand. If it does not get depressed ...
