Do you know the difference between EFI and fuel injected ? How is it "little different" as compared to other carbs ?? What is a conventional carb ?? Who told you Honda uses 80's carb ??? When was this "little different carb" which you are saying was invented ???
So after we have analyzed these theories of yours let me mention some facts.
Pakistani YBR is not a fuel injected bike, fuel injection doesnot require carb, it was invented to replace carbs.
The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created by intake air accelerated through a Venturi tube to draw the fuel into the airstream.
And if you had even bothered to do some research before coming on this forum you would have known that manufactures started putting fuel injected engine in their vehicles in the early 70's.
Now moving on to "little different". It's called a butterfly type carb as opposed to a slide type you see in Honda.
"Your highness" has so ignorantly classified slide types as "conventional ones" not realizing that both of these types were invented around same time in "1893"
What's the difference between the two types ?
CV or SLIDE CARB - The Great Compromise
Both the CV (butterfly) and "conventional" slide carbs are classified as variable venturi carbs. The slide on a "conventional" carb is directly connected to the throttle cable. Twist the throttle grip and the slide is raised in the venturi. On a CV carb the throttle cable is connected to a butterfly valve that varies the volume through the venturi. It's not the throttle, it's the pressure difference from the venturi to the outside atmosphere that moves the slide.
So which type is better? That depends on what you want to do. The "manufacturers" will tell you the CV is the next best thing to electronic fuel injection. It does feed a precise amount of mixture to smooth out throttle response, reduce pollution, and stretch your fuel budget and gas tank range however dont expect it to perform miracles as some newbies here are quoting cuz the only difference is the throttle valve.
The CV type carb suffers in the low to mid range torque however it does deliver peak output and max bhp
On the other hand If you can discipline yourself to control the throttle so that you don't bog your engine, then you want a conventional slide carb and that is why it is difficult to hold constant throttle on a cg125 cuz basically you are holding the slide.
Slide carb offers much more response and torque and is good for off roading as well.
Now i am pretty sure in some other thread it would be being said that since ybr has "butterfly type carb" it's performance is far better than CG and here it is being said that since it is a butterfly type or should i say "a little different" it is way more economical.
One almost feels sorry for these poor YBR chaps......they don't have a clue about the specs of their bikes and they can be seen in desperation challenging a market leader who sells lacs of bikes every year.
