Just another starting issue with Honda motorcycles

by Goldie 25. September 2011 02:45


As we can notice, recently we were writing a lot about Honda motorcycles and sure a lot about starting issues.  As you can notice by far, every motorcycle has its own specifics and every problem with each motorcycle part could have million different solutions.

In today’s blog post we are going to elaborate starting issue at 1980 GL1100 Gold Wing Honda motorcycle.  This motorcycle was stored for 2 years though it has new starter, good voltage and starter relay. The owner suspects: the starter switch could be bad and also the connections could be bad.  

Experienced motorcyclists would test all the electrical components first. Next motorcycle part for inspection would be the battery and its connections. These GL1100 Gold Wing motorcycles all have a permanent magnet battery charging system, consisted of a stator with three output wires, which go into a regulator. This unit regulates the AC into DC and then DC to 14.5V to ensure proper battery charging. Every connection between the regulator and the battery should be checked.

Also there are cases where the battery could have 12V and it doesn’t have enough amperage to give the starter real power.  There have been tests with new batteries when one cell is shorted or weak and the motorcycle won’t start. Also check if the battery is right for the motorcycle.

Furthermore, the problem can be located at the Stator and Regulator. In addition, as we can tell from the previous blog post stator and regulator failure is also common motorcycle part issue at 1980 Honda CB650.


Common motorcycle part issues at 1980 Honda CB650

by Goldie 18. September 2011 06:55

Every motorcycle series have common motorcycle parts issues more or less. One of these 1980 CB650 Honda motorcycle parts issues is turning off the field rotor when the charging voltage is too high; making the charging drop in which case the regulation circuit turns the field rotor back on. This issue sometimes is manifested similar to when the motorcycle is running out of gas.

The motorcycle ignition is battery-powered, so when the voltage drops down bellow 13.5V, the ignition system components shot down. Diagnosing bad rotor is easy, mount volt-ohm meter for testing the charging system output and the ohms value on the rotor tracks cold or hot.

Bad rotor can also cause bad regulator. When the rotor fails it draws too much current for the regulation circuit to supply, causing the regulator to die. This way this motorcycle part dies alongside the rotor.

Loss of spark can be caused by bad connection somewhere. Suspect any connection in the entire motorcycle. You can start diagnosing bad connection by taking off fairing motorcycle parts, the gas tank and seat, and disconnect all connections you find. Do these one at a time, and spray them with a contact cleaner before filling the connector again.

Also another motorcycle part could be suspected for resolving the issue. There is a vacuum-operated valve on these motorcycles. There is a fuel screen inside the fuel tank which requires draining the tank and removing the valve to draw the screen out from the inside the fuel tank. 

Weird problems with older motorcycle parts

by Goldie 16. August 2011 03:00

Today we will be making retrospective by interviewing experienced motorcycle repair guy about his rarest motorcycle part issues he ever collided. If you want to share some weird problem please feel free to comment down bellow. Note* we’re talking about problems connected mostly to really old motorcycles, age 20-30 years.



Weird motorcycle part problem - The headlight comes on/ doesn’t want to turn off when the motorcycle gets wet:


Whenever the motorcycle gets wet from washing or raining the headlight comes on regardless of the off position of the headlight switch or the ignition switch. The only way to turn the headlight off is to disengage the battery.



Weird motorcycle part problem solution:


The most probable issue is that the wiring is getting wet and it holds water. The motorcycle must get wet so the headlight comes on again and then you’ll need to track the connections to find the short.



Another similar and hard for resolving problem – the high beam control light and the rear indicators are on but the motorcycle itself doesn’t want to start. Just the same as the previous problem the battery needs to be disengaged and after the first starting attempt the condition is the same.


This issue is mostly connected to the wirings but for resolving it needs to be inspected more carefully and the solution depends of the motorcycle parts and of the motorcycle brand.  


As I said before everyone is encouraged to share their stories associated with unusual motorcycle parts issues.

Honda motorcycle/ATV ignition issue (again)

by Goldie 30. July 2011 06:25

Another motorcycle parts blog is up, this time we will explain Honda motorcycle / atv ignition issue. Motorcycle parts to check for solving this Honda motorcycle/ATV ignition issue:

Ignition coil.  The motorcycle part called ignition coil could be weak. A weak Ignition coil will shut down until it cools off– the only way to test it is to carry it into a dealer that has a coil tester. A weak trigger coil can do the same thing.

Battery.  Low battery voltage could also be the issue.

Sparkplug cap. Remove the sparkplug cap from the wire, counter clockwise, trim back a ¼ inch of wire and reinstall the sparkplug cap.

On/Off Switch. This switch might be bad, so check this for any case!

Connections.  Clean and put electrical grease on all connections!

Additional tip: Test the motorcycle parts when there’s not spark. .


I would recommend reading Honda motorcycle parts that affect the ignition system for additional thoughts on this issue.


Recognize your Honda motorcycle part when returning from repairs

by Goldie 26. July 2011 01:39

Today’s blog post will be about recognizing your Honda motorcycle part when returning from repairs. We’re not saying that all repair salons are ripping off their customers but it wouldn’t be bad a little carefulness.  We know few people who were installed different motorcycle part than the original one (intentionally or not intentionally). Best advice when going to repair salon is to do research in advance, in order not to look like total ignorant about motorcycle parts.

Now we’re going to present what-if situation about recognizing Honda motorcycle part, particularly - the Honda engine.

The first question when you forgot to write down your engine’s serial number before you send the motorcycle in repair salon would be:

How can I find out the engine’s serial number by the VIN number of the motorcycle?

Answer: The VIN number will not help you find your engine number. Honda doesn’t use matching numbers because often engines are pulled from the line for racing use.  The VIN number will only help you to narrow down the engine number range and expert can tell if the engine was the same year or not.

The only way to find your motorcycle’s serial number is to find the original MSO (Manufacturers Statement of Origin) that went with the motorcycle when sold new (The original bill of sale from the dealer). If you have owner’s manual, usually the serial number is in the front next to the VIN number.

TIP: Next time when you'll send your motorcycle in a repair salon I would advice to mark all motorcycle parts.

Universal motorcycle parts issues

by Goldie 2. July 2011 02:07

Do you have Harley Davidson motorcycle that warms up while running? What happens if you run your motorcycle with wrong battery.

The answer to these questions sometimes is simple and sometimes you’ll need help from experts to solve the issue. The following issues are more or less represented at same-brand motorcycles:

Issue 1:  Motor warming up at Harley Davidson.  Accompanying to this issue is having difficulty when getting into neutral while running and when you have to stop at traffic lights. On the other side your motorcycle doesn’t have difficulty getting into neutral before starting it.

Solution 1: There is no real solution for this issue because it’s quite common at many Harley Davidson motorcycles. Sometimes helps changing the oil into a different brand.

Issue 2: Running a motorcycle with wrong. Having installed wrong motorcycle part in your motorcycle is really wrong decision.  The charging system can be damaged and it might overcharge and blow out most of the light bulbs including the expensive front headlight.

Solution 2: The solution is preservation your motorcycle by installing original motorcycle parts.

Issue 3:  Old motorcycle doesn’t want to idle down. This motorcycle parts issue is common with old motorcycles that weren’t running for years.

Solution 3: The issue in the vacuum leaks around the shafts through the body that the butterfly valves pivot on. Sometimes they cause the linkage to bind up not letting the RPMs to drop off quickly. You can help to reduce the problem by backing out the mixture screw 2-3 turns.  


How to bring dead Kawasaki motorcycle in life?

by Goldie 22. June 2011 00:48

Today's blog post is going to be about figuring out the ignition problem with 2004 Kawasaki Ninja ZX-6R 636.  As usual we will go through several motorcycle parts and locate this issue in one of them.

First thing every motorcyclist would think of is charging the battery. After changing the battery if the motorcycle is still unresponsive the next thing to do is changing it with new one and check if and the cables are tightly connected to the power. If the motorcycle is still dead I would say good thought would be to check the battery.  If it’s okay then we should pass on the next motorcycle part.

Second thing on the motorcycle parts list for checking is starter relay. The motorcycle’s main fuse is on the starter relay. It’s located on the left side when sitting on the motorcycle just under the front left side of the seat. There should be a 30 amp fuse. Once the power gets throughout the main fuse on the relay - it goes to the other fuse box near the rear of the motorcycle under the seat. This fuse box has the ECU main fuse in it.

Third motorcycle part for checking (if all the fuses are okay) would be the relays on the left rear under the seat also.

Fourth motorcycle part for checking would be the ignition switch.

Also the ground circuit is important. Check the battery ground cable connections to the battery and to the frame.

If you or your friends have a Honda you can also read previous blog post about Honda motorcycle parts that affect the ignition system.

Old Suzuki motorcycle parts problem

by Goldie 14. May 2011 12:13


Having fifteen year old Suzuki? Well it’s time to do something about it. We’ll present the specific problem and mind map resolving, maybe you’ll find something useful for your old Suzuki motorcycle.

Having really old suzuki motorcycle parts? Our particular problem is associated with clutch issue. Before coming up of the problem there were new motorcycle parts installation such as: starter clutch and new clutch plates.

The motorcycle clutch issue appeared after 30 miles on the road. The owner of the bike is pointing out the master cylinder as motorcycle part that need the attention. In the clutch system, the motorcycle part which the master cylinder operates is called the slave cylinder; this motorcycle parts moves the throw out bearing until the high-friction material on the transmission's clutch disengages from the engine's metal (or ceramic/carbon) flywheel.

First thing you need to check is the hoses at the master cylinder. You might need brand new hoses because of the high ultra violet rays exposure.

Second, new air in the system means there is a leak with your motorcycle parts. It could be one or all of the following motorcycle parts: master cylinder seals, the slave cylinder seals, the lines or connections. Careful inspection checking for leaks after a thorough cleaning will give you the best chance of tracking this down. If no visible clues can be found, the next step may be a careful rebuild of the master and slave cylinders followed by a new hydraulic line.

Third, If there is crystallized fluid in the master cylinder- there might be crystals clogging the line. Therefore you could disconnect the line at the master and slave cylinder and try compressed air to clean the line or carburetor cleaner followed by air. Keep in mind if you blow air in the lines point the end of the hose in a direction where there is nothing but moonscape.

Next blog post will be more about Master Cylinder.


Maintenance of older motorcycle parts

by Goldie 1. May 2011 19:47

Now, new motorcycle parts are mostly used for replacement of old motorcycle parts. Old motorcycle parts are part of old motorcycle, consequently. It’s easy to suggest on buying new motorcycle and throwing out the old ones. Let’s see what we can do to preserve old motorcycle parts:  

·         Make sure you keep oil in the tank. Otherwise the engine will not be lubed. Generally the oil pump is located in the front right engine case. To see if the oil is getting to the pump there is a small bleed screw on the side of the pump and if you loosen it the oil should flow out of the hole.

·         Keep the spark plug clean

·         Check the air filter behind the carburetor. The engine will say thank you if you keep the filter clean. The air filter can take some oil but it may affect the running.

Other: The oil tank uses a good quality motorcycle two-cycle injection oil. This oil is used at older motorcycles.  This engine designs use total-loss lubrication causing “blue smoke” and other types of exhaust pollution. This is a major reason for two-stroke engines being replaced by four-stroke engines.

Can I mix two different fluids in my motorcycle?

by Goldie 9. April 2011 07:03


The above question is asked by whole absolute beginners with the motorcycle lifestyle. Here, we should note that there is silicon based and glycol based fluids. These two cannot mix!

Let’s do fluid time traveling. In the past all motorcycle fluids were glycol based. To satisfy the need of motorcycle racers the silicon fluid appeared on the market. Why racers do needed new type of fluid? The silicone fluid is more resistant on high temperatures which are typical at racing motorcycles.

Now let’s see the pros and cons of the silicone fluids. Pros:

·         Plastic and paint friendly

·         It doesn’t attract moisture as glycol fluid


·         Does not change color

·         Requires more frequent changes

Taking into account the cons, Harley-Davidson, manufacturer of motorcycle parts users of silicone fluids, warns buyers to let the fluid sit at least an hour before using it. The silicone fluid makes the motorcycle parts more corrosion prone just because it does not disperses moisture well compared to glycol fluids.

If silicone fluid was used previously, you should either continue to use that or you will have to flush the entire system of motorcycle parts with alcohol in order to use another glycol based fluid.
