No, it would not be possible to fit a carburetor on any truck.
Twin Weber carburettors will easily fit in the space otherwise occupied by the injection inlet manifold. Dellorto and other companies distribute an inlet manifold specifically for for fitting Weber 40s and 45s.
NO.
Yes it will fit, I have a 98 carb and my 86 model kx125
how fast would it make the bike
1987 is the last year for a carburetor.
You can try to get a bigger carburetor for the bike. The XR80 carburetor will fit with some modifications. Another possibility is to bore the engine out to 90 cc but then you will need a different piston and rings.
Yes it will just be sure you use the wright carb. base gasket.
yes ,i've done it to a 302 and it ran fine
i do not know what is meant by "converter", but all that needs to be done is to unbolt carburetor and intake from the one and bolt it to the other.
Yes - as long as it is using the same size intake manafold.
