Cagiva Mito Engine recommended rebuild parts


Rebuilding the Cagiva Mito 125 engine requires precision, especially regarding the balancer shaft and crank alignment. This updated guide highlights the "hidden" steps often missed in the standard workshop manuals.

Critical Rebuild Checklist

Before closing the casings, ensure you have checked the following:

  • Crank Shimming: Did you remember to use the 0.5mm shim on the LH-side behind the main crank bearing? Failure to do so affects primary drive alignment.

  • Balancer Timing: The workshop manual (WSM) is notoriously vague on this. Use the factory build settings: align the dots on the primary gear and the balancer gear precisely to avoid heavy vibration.

  • Water Pump Clearance: Check the aluminum impeller clearance against the oil seal and ensure the plastic drive sprocket isn't rubbing the RH-casing wall.

  • Crank Alignment: Ensure the crankshaft is perfectly centered between the casings to prevent premature bearing wear.

Technical Timing & Tools

The timing tool shown in the video is becoming increasingly rare. If you cannot source the official Cagiva tool, timing can be set "by eye" using the marks on the flywheel and stator, but a dial indicator (DTI) is highly recommended for setting Top Dead Center (TDC) accurately.


Note: Always test and bleed the oil pump after a rebuild. Running a fresh engine without confirmed oil flow is the quickest way back to a strip-down!

Over the decades, Cagiva produced several versions—ranging from the early 7-speed Mk1 models to the final SP525—each with unique port timings and combustion chamber shapes. Using the wrong piston-to-cylinder combination or mixing incompatible heads can lead to poor performance or catastrophic engine failure. Use the codes below to identify your setup. Common Cylinder Barrel Codes The identification code is usually cast into the side of the barrel, near the base or the exhaust port. 73037: The "Standard" Evo barrel found on many 6-speed models from 1994–1999. Known for reliable power and good port timing for street use. 66650:...

Cagiva mito 125 for sale here on Ebay UK Cagiva mito 125  parts for sale here on Ebay UK  How to Derestrict the Cagiva Mito 125 (Full Power Guide) The Cagiva Mito 125 is famous for being one of the fastest learner-legal bikes ever made, but many are still restricted to 15bhp. To unlock the full 30bhp+ potential of the Mito Evo engine, you must remove the factory-fitted bottlenecks. IMPORTANT: You must perform all three steps below at the same time. If you derestrict the air and exhaust without re-jetting the carb, the engine will run lean and likely seize within minutes. The 3 Stages of Mito Derestriction 1. The Exhaust Expansion Chamber The standard exhaust has a "plenum chamber" (a small blind pipe) welded near the manifold. This disrupts the exhaust pulses and kills power. The Fix: Use an angle grinder to cut off the plenum chamber, weld a patch over the hole, and grind it smooth internally. Alternatively, swap to a Giannelli or Arrow sports exhaust for an immediat...
