Common motorcycle part issues at 1980 Honda CB650- Part 2

We’ll be continuing the “1980 Honda CB50 motorcycle part issues” saga. Why? Well, it seems in many cases the previous blog post isn’t enough in resolving the motorcycle part issue. For the previous part, you can find the blog post here, "1980 Honda CB50 motorcycle part issues".


So, after the alternator, battery and gas are all checked, we should move our suspecting on other motorcycle parts:


Pulse generator - This motorcycle part could get hot and after the motorcycle goes on the road, the difference between temperatures makes it break down.   


Battery - Again we’re referring on the two spark units mounted back by the battery. If you see black emission down from the units, they may be weak.  


Spark Plugs – Connect spark plugs to the two outside cylinders and check them for spark. Notice if they look overheated from a lean condition. If it loses one coil, it could be the coil overheating or the spark unit acting up. If the spark plugs are good we’re moving on the next motorcycle part.


Vacuum hoses - Check if the vacuum hoses to the automatic fuel valve are tight. If they’re not tight, you can get vacuum leak and fuel supply loss to the carburetors.


Extra tip: Quick check your charging system by watching the headlight bulb intensity. If this light brightens up when you rev the motorcycle, than probably your motorcycle is doing okay.



Recognize your Honda motorcycle part when returning from repairs

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.
