What You Demand :

– Starting fluid (ii-5$ at your local auto parts store)

– Tools required to gain access to and remove the air box covers or lids holding the air filter in place

– Your bike with a charged and capable battery to plow the engine through efficiently

– A mind to be blown past your own capability

Situate the bike outdoors and in the proper orientation as if yous where going to starting time information technology regularly. (fundamental on, kill switch on, in neutral, side stand down) After y'all accept gained access to the air inlet for the carburetor intake. Which sometimes requires removing the air filter or just figuring out where the air box is sucking in air from. Take your starting fluid and give the intake port two to 3 quick sprays while turning your engine through with the starter button. I like to take the throttle open during this as well. What happens adjacent is what is the most important effect to heed to. In most cases you will quickly realize a difference in the engines reaction of the spray by hearing that the engine picks up and reacts quickly to your throttle only to then either cut back off or run poorly equally it did before. (Depending on what symptom you are diagnosing.) Give it a second try with the same technique to get a full understanding of how the engine is responding. If there is whatsoever change to how the engine reacts, your on your style to having a solid foundation for a complete diagnosis.

Diagnostic results breakdown and understanding

In a NO Commencement condition after the bike has been sitting (main cause of a partially or fully clogged carburetor) and you lot physically add a highly flammable fluid into the combustion chamber information technology allows the motor to react by either idling smoother, choice up in RPMs and/or react more than to the operation of the throttle. The engine is telling you lot a number of things.

1. I have enough pinch to complete my combustion cycle. So there is no potentially excessive pinch leaks through the valve train.

2. I have spark, and so all ignition components are likely not the issue.

3. The carburetor is unable to give me the fuel I demand in it'due south current state. By forcing the starter fluid contents into it's intake, bypassing the clogged jets. It'due south only response is to run "meliorate" due to the added consumption of burnable material your allowing.

BINGO! Your carburetor is gunked up and in need of a rebuild or cleaning.

Already cleaned the carburetor(due south)?

All the same running poorly?

Even on a running motorcycle that nonetheless doesn't seem to operate and react smoothly throughout the throttles ranges can be put to the examination with this trick. If you spray the starting fluid into the air box and it seems to smooth out and react apace to your throttle blips. Information technology even so is not clean enough. This indicates a lean mixture. For you custom build guys using individual pod or single type filters this process will all the same work and help you figure out which carburetor is having trouble. Depending on where the runnability issue is hanging up (idle,mid range or wide open throttle) information technology volition tell you exactly whats restricted with the spray.

Recollect that this technique gives you multiple answers to the condition of your engines vital systems that allow it to run. It's reliable and proven to work.
