For those interested in a little more than our Sport build, our MB50 build could be the right build for you! The MB50 is our Sport build plus our crank, pistons, rods, and valve covers. If you're still wanting more, check out our Kohler 25 Roller

The Kohler 25 MB50 starts out as a brand new Command PRO CH740 (Kohler's big block v-twin 25 horsepower carb option). We take this engine and replace a number of stock parts with our own parts to greatly improve the performance and reliability of the engine.

This build includes the stock engine with our following parts installed -

  • MHP Forged Crank
  • MHP Reworked Heads with Manley PRO-FLO SS Exhaust and Intake Valves and Heavy Duty Springs
  • MHP Steel Muffler (Optional)
  • MHP Reworked 30 mm Downdraft Command Carb
  • Custom Diamond Pistons
  • MHP Billet Rods and Rod Bearings
  • MWSC 4000 Cam with Hydraulic Lifters
  • MHP Valve Covers
  • MWSC Command Air Cleaner Adapter
  • K&N Filter with Custom Filter Top and Bottom Plate
  • Replacement Gaskets and Dowel Pins

We build and dyno every engine in-house. A dyno run of this build resulted in 55.4 ft-lbs of torque. Max power was reached at 4450 RPM.

The list price of this engine includes free shipping and our 3 year warranty.
