The main task of the carburetor is to mix Fuel + Air. Roughly in the ratio of its range Fuel: Air is 1: 13-15. Anyway how do I let the machine would be fed a mixture with a ratio as mentioned above.
Why wear range, whereas the theory in the book the ideal burning 1:14?
The answer is Because of the condition of the engine and environments affect mixture settings Fuel: Air.
For example:
The higher the compression, the hotter the engine and fuel supply need more let machines do not breached.
Humidity (humidity) environment higher, then mix Fuel contaminated water, and the mixture getting poorer, MEAN gasoline should be more.
Ambient temperature is low, the working temperature of the engine down, and gasoline should be reduced so that the working temperature of the engine so ideal.
Free flow exhaust,, the higher rpm, and the engine temperature will rise, MEANS need Fuels higher.
And there are many more parameters that must be considered including the design of the inlet on the block by setting the influential Fuel nozzle as the dealer.
That theory essentially.
Carburetor settings
Carburetors have 2 nozzle:
One piece of the main jet (for standard size NSR 130) who plays distribute fuel when the throttle about half a lap up.
A single pilot jet (NSR standard size 45) who plays distribute fuel from the gas rotation 0 degrees until full, but the effect of these jet pilots could be said not too significant at full throttle engine rpm N is already high.
Another thing that affects the settings including:
Size Venturi carburetor
needle skepticism
setting the wind
Power jet.
Venturi carburetor bigger then the more air that passed so need a bigger nozzle either the pilot or main jet so that the mixture could be right.
Then when we increase or decrease the nozzle before?
Previous to know when the first symptoms of deficiency Fuel engine and most of Fuel:
1 Symptoms such as loss of engine power due to shortage of fuel which
2 Symptoms of machines that actually feels like a solid but restrained power and sometimes accompanied by metallic banging noises if the settings are too wet.
Means if experiencing symptoms at points 1, the engine needs fuel, if experiencing symptoms at point 2, the engine mostly Fuels.
Cases
Well here is often the case that the problem occurs because the pilot jet:
Motors that morning because it's so hard to live ngempos opened the gas continues to raise the dead it means the pilot jet.
The motor is the way to normal but often suddenly lost power when a low round n round gas jet pilot means raising
Motors are often over-heat when the means to raise the pilot jet slowly
Motor symptoms point 2, in the run-down but well over a lap top means the pilot jet greatness.
The motor does not use the choke if N can directly start the morning
(This is also not normal) means the pilot must come down.
In conclusion, if there are symptoms of points 1, high temperatures are relatively low diputaran then ascending the pilot jet, if there are symptoms of points N 2, at low speed, the pilot should also go down.
For the main jet cases:
Motor firm to take the road round continues so to finish way up slowly so experiencing symptoms of points 1, accompanied by exhaust fumes, MEAN temperature increases dramatically when high rotation, ask MEAN main jet up
Breath motorcycle on lap top means the main jet is too long'm riding.
Motor had a knocking when the other normal, engine temperature MEAN VERY HIGH when the lap top, the main jet'm riding.
Motor experiencing symptoms point 2, on lap top just means the main jet'm down
etc.
In conclusion, if the motor menalami symptoms point 2, on lap top means the main jet should be dropped, if the motor temperature is high in the run-up means the main jet'm riding.
Note:
Any changes required to setting wind nozzle size
Do not have relied on the temperature indicator on the dashboard to guide the setting because certainly does not fit, it takes a jockey who feelingnya already strong.
Sometimes detonation can not be fixed with naekin detonasinya nozzle if it is severe. This means there ketidaknoarmalan on other engine components.
