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.
