This video explains when and when not to warm up your engine
Motorcycle technologies continue to develop at breakneck speed. From ABS to radar-assisted cruise control, from six-axis IMUs to MotoGP-inspired winglets, manufacturers are pushing the limits with more safety and performance-focused upgrades. However, one of the most revolutionary developments in recent history is the transition from carburetors to fuel injection.
The majority of modern models require the latest fuel system in order to meet current emissions regulations, but a small handful of bikes still stick to their trusty carbs these days. We’re looking at you Suzuki DR-Z400SM and Honda Navi, but we at RideApart appreciate old-school motorcycles, too.
For folks on both sides of the carburetor/fuel injection division, RevZilla’s Ari Henning explains when and why a motorcycle engine requires a warm-up period in the latest installment of the Shop Manual. If you tend to err on the side of caution and warm up your fuel-injected bike, Henning’s breakdown and advice should put you at ease. His thorough yet digestible explanation helps even new riders understand the demands of their bike, whether it’s carbureted, fuel injected, cold or hot.
While Henning’s sage advice will cover a vast majority of vintage and modern bike owners, viewers should also understand that modern emissions standards don’t always translate to optimal fueling. As Jason discovered with the 2020 Indian FTR 1200, some brand-new motorcycles still require a warm-up period despite having modern fuel injection systems.
From a bird’s eye view, most carbureted models will need time to reach optimal fueling depending on climate, altitude and engine specifications. The reverse rule generally applies to fuel-injected bikes, but every bike is unique. Now that viewers understand the idea behind warm-up periods in general terms, they should also consult their owner’s manual for model specifics. As mentioned earlier, motorcycle technologies are constantly changing, and what works for you may not work for everyone.
