Description

EC Carburetor's Brand New 228R Racing Engine


EC Carburetors are the purveyors of performance and innovation. Working with companies like Tillotson Racing, we can build engines and components that raise the bar in small engine performance without draining your wallet. Our new 228R engine is the next step for our growing engine lineup. This engine goes beyond the spec 225RS with more stroke expanding its capabilities and power potential to make the ideal mini bike engine package.

72mm Tillotson Reinforced Block - EC Carburetors designed the Tillotson Reinforced Block to create new engine packages like the 225RS and 228R and other highly modified race engines. We made the block thicker and more robust to reduce flex and distortion; this prevents power loss through crank flex and blow-by between the piston and cylinder.



Tillotson Racing Lightweight Hypereutectic Piston: The piston uses the latest technology and design utilizing racing slipper skirt vs. conventional barrel skirt design of other stock pistons. This piston uses an aluminum alloy with high silicon for a lower thermal expansion coefficient, allowing tighter tolerance for superior performance and longevity over stock Chinese cast pistons used in other engines and kits. The low slipper skirt design also allows more clearance in the rotating assembly for larger stroke crankshafts. We also made the compression height shorter by moving the pin's location and using a smaller diameter wrist pin. These improvements allowed the use of a longer rod while reducing weight in the rotating assembly.



Tillotson Racing Rings: Tillotson Rings are specifically designed for the Tillotson Racing Lightweight Hypereutectic Piston. These rings reduce friction and increase cylinder sealing to improve mechanical efficiency compared to other stock piston ring sets. We specify the ring tension to be better suited for racing applications.



EC Forged Rod: EC Carburetors designed the original forged rod for Tillotson 225RS engines, using a 55mm stroke crankshaft. Our new EC Billet Rods are designed to allow more stroke with standard clone journal crankshafts and bigger camshafts. Using what we have learned in the development, we made a stronger rod for RPMs above 6500rpms and higher output. This rod is made in-house and is exclusive to our engine combination.



56mm Crankshaft - Our 228R is the first racing engine to come standard with a 56mm stock forged crankshaft. There is no replacement for displacement. We're giving you an additional 4cc. Standard 225 engine 72Mm bore x 55mm stroke = 223.93, EC 228R 72mm Bore x 56mm Stroke = 228. The increased stroke will help make additional power across the board with a nice bump in the lower RPMs. Using the Tillotson Racing Lightweight Hypereutectic Piston, we have more than enough room for the additional stroke where other stock cast pistons do not.



.265 Banzai: EC Designed this cam for a broad torque band specifically for mini bikes and karts that need excellent low-end torque, whether it's accelerating from a dead stop or low-speed cornering. Peak power is around 7500, but with our 26lbs springs, we can rev the engine over 9000rpms though this is not recommended for longevity. The cam would be duplicated for the 225RS engines as it was ideal for spec engine sprint racing.



Tillotson Racing Cylinder Head: The Cylinder head is another EC-designed component initially designed to make the best performing head in the 196 box stock classes. The 196R cylinder head is modified for the 212R and 225RS engines. We increased the stock 25/24mm valves to 27/25mm and went from 5.5mm stems to 5mm stems from the increasing flow. The modifications makes the head well suited for the performance goals of our 228R engine.



EC VM22 Carburetor Kit: We have taken one of the most popular carburetors used on mini bikes and made it better. The Chikuni(Chinese Mikuni) carburetor is taken from the best castings by going direct with the carburetor manufacturer, then machined and blueprinted by the world's winningest small engine carburetor builders. Not only is this a considerable jump over the stock carburetor, but it's also a leap over re-jetted identical carburetors sold through kart part warehouse distributors. We also built our intake manifold to better fit on mini bikes or other chassis where space is limited. This intake also improves the signal to the carburetor and allows more airflow resulting in better performance. This carburetor is the maximum size for this combination of parts. before adding a larger carburetor you will need a big valve ported head, larger cam, and roller rockers.
