RIDEFAST DECEMBER 2021

This led to the death of so many cool
2-stroke models, particularly from
Japanese manufacturers.
Supposedly their smoke – our favourite
cologne – was way too polluting and
damaging to the environment and the
ozone.
Really?
Uhm, weren’t diesel vehicles considered to
be the preferred ‘Green’ mode of transport?
Have you seen how they smoke?
Have you breathed in that crap? Jet
planes?
Somethings stinks here… and it isn’t 2
stoke smoke.
It has taken a few dedicated years of
hard work by a heroic few to design a
fuel injection system for 2 strokes that is
becoming acceptable to the tree huggers
and politicians. We are pretty sure we’ll see
this tech seeping through to other brands
as controls tighten up.
A quick side note. We know for sure that all
EU spec bikes come into the country with
full emissions packages onboard on both
2T and 4T, (dirt bikes in particular), and
that they are removed and the mapping
gets changed by the importers. Yup, dirt
bikes also come with catalytic converters,
charcoal filters, lambda sensors, solenoids
and actuators that all get removed before
they hit the showroom floors.
The
wait is over
“2T or not 2T?” that is the question…
Supposedly 4T bikes burn cleaner, have
a better longevity and are more rideable.
But they also have more working parts,
valves, valve seats, valve guides, valve
springs, shims, shim buckets, rocker
arms, cams, timing chains, timing chain
guides, timing chain tensioners and a
bunch more stuff that 2T motors don’t
have and don’t need.
4T motors are more fuel efficient and are
generally kinder to the environment.
However, the advent of the fuel injected
2T motors and advances in cleaner burning
2-stroke oil is making 2- Sroke tech
more acceptable.
Some, like the KTM groups TPI system
with its sensors, ECU’s and fancy
technology does all the thinking for you,
negating the human factor out of the oil
fuel mixture, and ultimately making a
cleaner ride.
Also, for endurance and extreme race
and riding like The Roof of Africa for
instance, every time the rider stalls and
restarts, the sensors kick in, check conditions
and sends that info back to the
ECU which adjusts air fuel accordingly to
achieve optimum performance – and the
cleanest possible burn.
Is the fun, character and charm being
engineered out of our bikes by all the
emission control systems and all the new
electronics and technology - or, is it just
making it different, better and we need to
move with the times?
Modern bikes in most instances are mind
blowing, ridiculously fast, amazingly
stable and easy to ride in any conditions.
They might not shake, rattle and roll like
the old bikes, but they do snap, crackle
and pop when you twist hard on the
throttle in full sport mode and bang even
harder on the quick shifter.
FUEL INJECTION vs CARBS.
Fact: Fuel injection burns cleaner than
Carburettor.
The only real advantage carburettors
have over fuel injection is that they can
be fixed almost anywhere. The trick
comes in fine tuning them or setting
them up for different altitudes, air pressure,
humidity and etcetera.
Fuel injection seldom gives trouble – in
our experience the fuel pumps tend to
give in after lots of mileage, but you cant
just fix them on the side of the road.
Fuel injection barely ever clogs up with
old fuel, basically because there is no
float bowl or jets to speak of. Fuel injection
is also self-correcting every time
it starts. That’s where all your sensors
come into play, communication with your
bikes ECU (Brain).
