Cagiva Mito 125 Mikuni carb TM35 35mm Carb Jetting / Strip down




The Mikuni TM35 is the "holy grail" of carburetors for the Cagiva Mito 125. Standard on early 7-speed models and high-end racing setups, this 35mm flat-slide carb offers a massive performance boost over the standard 28mm Dellorto. However, with increased performance comes the need for precise maintenance.

If your bike is stuttering or failing to hit the powerband, a thorough strip-down of the TM35 is often required to clear the delicate internal passages.

Mikuni TM35 Original Factory Settings ('95 Racing):

  • Main Jet: 310

  • Pilot Jet: 45

  • Jet Needle: 6AEL4-60 (4th clip from bottom)

  • Throttle Slide: 5.5

  • Air Screw: 1.5 turns out from closed

Step-by-Step Strip Down Guide:

  1. Safety First: Drain the fuel bowl into a glass jar. Check for debris or water contamination—even tiny particles can block the TM35's sensitive jets.

  2. Slide Removal: Unscrew the top cap and carefully pull out the flat slide and needle. Inspect the needle for wear or bending.

  3. The Float Bowl: Remove the four screws at the base. Be careful with the gasket; these can be hard to source individually.

  4. Jet Cleaning: Remove the Main Jet and Pilot Jet. Use a dedicated carb cleaner or, better yet, an Ultrasonic Cleaner to ensure the internal "emulsifier" holes are clear.

  5. The Float Valve: Inspect the needle valve tip. If it has a "ring" worn into the rubber, it will cause the carb to leak fuel from the overflow.

Tuning Tip:

If you are running an "Aftermarket" setup or a sports exhaust, many owners find success moving to a 350 Main Jet and a 20 Pilot Jet to prevent the bike from running too lean at high RPM.

 its always advisable after any change to do a plug chop test (see below) to test combustion conditions , this will give a clear indication of the jetting state , also its recommended to increase jets size 5 points for any sports airfilter or exhaust fitted again do the plug chop test to ensure correct running conditions

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...
