Right you are,
Interesting the differences between the bikes and cars. The old basics were
always the valves/ports etc., with things like the tunnel rams or spacers
playing
with the intake length/volume after the carb. Bikes had one carb per cylinder,
usually with a K&N right on each carb, and intakes that often took nasty twists
to fit.
Now, I look into the intake of the ST4 and I can see the valves, and the
manufacturers fight to give the airboxes as much room as possible. The
manifolds
for the cars have banks of foot-long intake runners. With injectors spitting
right on the valves (somebody mentioned carbs being better for atomization; fuel
droplets from a carb are bad as they can drop out, but if you have droplets
injected right into the cylinder, I would guess it isn't as bad and I wonder if
it could even help cool if it has the chance to evaporate before burning..hmm)
it
seems that airboxes and intake runners are the new areas of potential gains.
Other than stack stubs the idea used to be just have it as open as possible.
These are just musings, and I know there are so many variables; twins are
different than fours etc., but it is fun to compare them all.
Cheers,
Rick
