How does the carburetor work on a Suzuki S40?
While the performance of other engine components depend, to a large extent, upon rpm, the carburetor only responds to the position of its throttle valve (slide) and the amount of air flowing through it (and sometimes the direction of that air flow).
When does a carburetor backfire what does it mean?
Don’t be mistaken… After-burn is similar to back-fire, which is the burning of fuel in the intake port of the carburetor. Both conditions occur when a very lean air/fuel mixture burns so slowly in the combustion chamber that it is still burning when the exhaust and/or intake valves open.
Can you change the carburetor on a Suzuki Savage?
No carburetor adjustment, ignition adjustment or exhaust system can change this. Ignitions with quicker advance curves improve throttle response and part-throttle performance in the mid-rpm range, especially below 3000 rpm.
What causes Suzuki Eiger 400 to hesitate and backfire?
Suzuki eiger 400 hesitates and backfires What is the on/off position of the choke lever. I’ve cleaned/rebuilt carb replaced spark plug, flywheel, stator, fuel valve, fuel filter, main (choke) diaphragm with plunger and CDI. When in neutral and I accelerate it hesitates sputters and backfires, but eventually builds RPM.
What causes a carburetor to back fire on a motorcycle?
The burning of excess fuel in the exhaust ports or exhaust piping from a drastic change in pressure, causing a very LEAN air/fuel mixture from the carburetor. Don’t be mistaken… After-burn is similar to back-fire, which is the burning of fuel in the intake port of the carburetor.
Is the Suzuki Boulevard S40 a good bike?
There´s a good reason so many road bikes in the ´50s and ´60s were big single-cylinder machines: they´re incredibly fun to ride! The Boulevard S40 adds a shot of advanced Suzuki technology to this timeless design to create a bike that combines exciting performance with rock-solid reliability.
What causes a carburetor to burn so slowly?
Both conditions occur when a very lean air/fuel mixture burns so slowly in the combustion chamber that it is still burning when the exhaust and/or intake valves open. Now back to the list… 2. An extreme or “constantly rich” mixture where unburned fuel ignites in the exhaust ports or exhaust piping (same as number #1 with a different cause).
What happens to the fuel mix when you go back to idle?
The drastic change in velocity (back to idle/from the high pressure to low pressure) slows down the air/fuel mix abruptly. This makes the mixture linger and hang around the combustion chamber longer.
