Re: Low gas mileage!
I have 2 bikes with 69cc engines and I am using 40T sprockets. One engine
is straight sparkplug style with the old style carburetor. I run at full throttle on this
one most of thev time. I get gas milage like yours.
One bike is the slant head plug with the new style carburetor. This bike runs
about equal in speed at half throotle and scares me at whole throotle because
I am running with a rag style sprocket adapter. I am also seeing alot better mpg
with this one.
Do you think that it might have something to do with the carburetor slide?
For some reason the new style carburetor has alot more throotle than the old style
carburetor that I am experiencing.
