Luc,
I think it's the opposite. The smaller in front and larger in rear,
the
faster the engine turns for the same speed. The 14/47 is great for
off-road. The 16/47 extremely close to the factory 15/43. I use the
15/47
as a compromise between added torque/power at lower speeds and the
capability to maintain 65 down the interstate. I don't usually try
to run
75-85 down the interstate, but if I need to, I go to the 16/47
combination.
On my '95 it's 5 screws to change the countershaft sprocket, 3 for
the cover
and 2 for the sprocket, then adjust the chain if I'm going from the
16 to
the 14. If going from the 14 to the 16, then I have to loosen it
before I
start.

Thanks y'all for the fantastic, hands on, " been there,done that
"feed
back on the carb. Now, for some reasons the conversation switched to
sprockets..
That's good.. 'cause I'm kind of lost when it comes to teeth. On my
childhood bicycle, the smaller the sprocket in front and the bigger
in the
rear the faster you would go depending on how strong your muscles
were. On a
35-40 HP ( ?) engine what would be
the "Ideal " combination?
