Tillotson 225RS was developed by EC Carburetors as a new spec engine for sprint kart specifically but with its performance and value find it's way into other motorsports. Here we have complete 225RS Engine as well as many upgrade kits for the 72mm 225 blocks to build beyond the spec engine class. While Tillotson is still developing the carburetor for the engine, EC has created a modified version with the 228R by stroking the engine 1mm and adding a tuned slide carburetor ideal for mini bikes. EC also created the 236R short block kit for those running in 14.5ci open or RWYB(Run what your brung) modified classes. These 236R kits have completely changed the clone engine market for those wanting the best performance without breaking your budget.
