fuel consumption (one for the phd's and pe's)
Posted: Mon Jun 26, 2000 10:43 am
This should start a good thread. I have this bike (say a KLR) that
burns 1 gal of per hour (gph) at 50mph. Lets also say for arguments
sake that it takes 10hp to maintain a steady speed of 50mph. Way is
it when I change to a larger jet in the carb the milage goes down?
Now know the typical Harley tuner says "because your burning more
fuel", duuhhh... But if I still require 10hp to do 50mph then the
burn rate should stay the same. If I'm burning more fuel then I'm
making more hp and I need to back off (reduce throttle opening) to
maintain 50mph. Of course I know that the bike is now more fun to
ride hard and I have the 'normal' reaction to twist even harder but
if I'm just cruzin down the 'slab then burn rate should be the same.
right??
