with an optional connec-
tor for the throttle position
sensor, which is needed on
the Beta due to the standard
oil-injection system. We
were feeling much smarter
after some further education
on the SmartCarb history
during a quick 30-minute
install. We were back out on
the bike and ready to see if
the SmartCarb could really
outsmart these technical
trails.
Each bike will have a
recommended needle and
you use the external ad-
juster that moves the needle
up (richer) or down (leaner)
for fine tuning. From the first
blip of the throttle all our
senses lit up with the im-
proved responsiveness from
the SmartCarb. We saw less
smoke out the back, heard
a crispier tone, and felt a
stronger pull from down low.
Like we said, the bike ran
great with the standard Kei-
hin but there was a notice-
able improvement with the
SmartCarb. The Beta felt
torquier in the tight single
track and was able to hop,
jump, and skip over rocks
with a quick twist of our right
hand. Overall, this made it a
lot easier to attack the tight
Beta in stock trim to get a good base
setting for our back-to-back comparison
before installing the SmartCarb.
After getting a good baseline, the TE
crew helped us install the 36mm option
for our carbureted Beta. The SmartCarb
quickly replaces the OEM carb and
accepts the stock throttle cable along

SmartCarb uses a closed-loop design.
