First Look: SmartCarb – a ‘smart’ look at the carburettor problem
Better fuel consumption, more power, way less emissions – what’s not to like about the SmartCarb? We’ve taken a look at this ‘smart’ take on the old problems with carburettors...
The SmartCarb is “the most advanced mechanical fuel system available today for off road and racing motorcycles” say Technology Elevated, manufactures of the SmartCarb.
It is a bold claim but in a world increasingly conscious of emissions and pollution, where two-stroke off-road bikes are under the cosh, don’t we need this kind of technology to keep us going?
Literally a smarter carburettor – the SmartCarb is a modern flat slide, single circuit, metering rod style carburettor. Effectively a replacement for your stock carburettor, which the manufacturer claims significantly outperforms a regular carburettor with 30% better fuel consumption, 10% more power and 50% better emissions.
The technical bit…
The patented, single circuit design uses a metering rod for fuel delivery, a variable shape venturi and internal venting to drive fuel flow proportional to changes in air density. Effectively that means it delivers fuel dependent on throttle opening but also altitude, temperature or even boost.
Manufacturers, Technology Elevated, claim these features work together to provide extremely fine fuel atomization – smaller fuel droplets increase the burnable surface area of the fuel in the mixture.
In turn that means more a powerful and “complete” combustion, which increases horsepower (by a claimed 10% or more) and reduces fuel consumption (by a claimed 30% on average). A major knock-on effect of that is a reduction of emissions by up to 50% and has been EPA certified, twice.
A big bonus with the SmartCarb is the lack of maintenance needed. Any adjustments are made externally, quickly and by hand, and because there are no jets to change you don’t need tools or to get inside the carb’ at all – so now more jetting changes to suit weather and altitude.
There’s also no fuel spillage through overflow pipes as you so commonly find with conventional carburettors.
Ease of use
Though clearly a complex design, from a user point of view the SmartCarb appears to be incredibly simple to operate and maintain. There are only two adjustments, and both can be made by hand – the clicker adjuster on top lets you adjust the fuel flow and an idle screw on the side changes rpm.
Notable competitive successes include:
Pikes Peak International Hill Climb – two world records, three first place finishes, six top 10 finishes
British Extreme Enduro Championship – first in class
Edge Offroad Enduro Championship – first in class
Red Bull Romaniacs second place in Iron Class
Three world records in NSSC Drag Scooters
UAV 50cc altitude record at 22,000 feet
50cc Australian land speed record
If this all seems a bit like a long advert for SmartCarb, it isn’t. We’ve been mulling over the details for a while and still keep wondering, if it is that good then why don’t manufacturers fit them to stock bikes?
The fact is SmartCarb is a proven component on the trail and in competitions like Romaniacs. It competes directly with electronic fuel injection systems on enduro/off road bikes to both pass emissions regulations and meet performance requirements. By all accounts it is easy to use, cuts fuel consumption, crisps up throttle delivery and improves power. If it cuts emissions too then what’s not to like?
Fitment details: Technology Elevated focuses currently on the off road two-stroke and four stroke markets, with 25, 28, 36, 38 and 40mm SmartCarbs to fit from 65cc up to 500cc (there are options outside that too).
Cost: 38mm Cast SmartCarb $474.00 – $499.00. 36/38/40mm Billet SmartCarb $599.00 – $699.00
