Quote: A 1 1/2" primary carb(850) on a small-inch low-rpm MPG project ? ...
You never saw the thread?
Yes I saw it RT .. but it never registered that it was a 850. HONESTLY ...I think that some more MPG could be gotten with the 800 carb ... and MAYBE some-more with a reduction of the vent size ON TOP....or on the bottom.
Now to HYPER - ...will he EVER get his ride fixed ? ... ME THIMKS not ! ..
