Complete 85cc Tuning Kit for Your Piaggio Ape!
Build your ideal conversion kit yourself. From high-quality cylinder kits to the right tools and the correct main jet, you will find all the components you need for a successful engine upgrade here.
What do you need for a successful 100cc conversion?
1. A larger cylinder
Choose a high-quality cylinder kit from manufacturers such as Polini, DR Racing or Pinasco for the best and most reliable results.
2. A performance exhaust
A performance exhaust is designed to match the engine's modified characteristics and can improve power output. The right exhaust helps remove exhaust gases more efficiently, allowing the cylinder to perform at its best.
3. 19mm Carburetor
For engines with a displacement of 100cc or more, we recommend installing a larger carburetor. This ensures that the larger cylinder receives sufficient air and fuel for optimal performance. With a 19mm carburetor, the engine can deliver more power and benefit from improved fuel delivery.
4. A larger main jet
The larger cylinder changes the engine's fuel requirements. Fitting the correct, usually larger, main jet ensures that the engine receives sufficient fuel. For an 85cc setup, a size 64 jet is often sufficient. The jet must be carefully calibrated to prevent a lean mixture and avoid engine damage.
Please note! If you choose the Polini CP carburetor, do not order M5 main jets. The Polini CP carburetor uses KEIHIN PWK jets.
5. A colder spark plug
A spark plug with a colder heat range can help prevent overheating when the engine is subjected to increased loads.
6. A reinforced clutch
A tuned engine places greater demands on the clutch. As a result, the original clutch with three friction plates may wear out more quickly. A reinforced clutch is therefore recommended.
Pay close attention to the engine type when ordering:
Older models: Engine codes TL1M and TL2M, models TL1T to TL4T, with a single central pressure spring.
Newer models: Engine code TL3M and the C80 series, models TL5T, TL6T, ZAPC80 and ZAPC81, with six pressure springs.
Always check compatibility with your specific engine before ordering a clutch.
7. Modified primary gearing
With modified primary gearing, you can better match the speed and engine RPM to the increased engine power. Taller gearing can provide a higher top speed at the same engine RPM. This can be achieved simply by replacing the original 14-tooth gear with a 16-tooth primary gear. We recommend the Pinasco gear. Cheaper alternatives often produce a high-pitched whining noise.
8. The correct installation tools
Specialist tools are required for proper installation, including:
Flywheel puller: To safely remove the flywheel and gain better access to the cylinder kit.
Clutch puller: To remove the clutch.
Clutch repair tools: To correctly disassemble, modify and reassemble the clutch.
Build your ideal conversion kit
With the right components and suitable tools, you can prepare your Piaggio Ape for a powerful 85cc configuration. Choose parts that suit your engine type and intended use, and pay careful attention to carburettor tuning, ignition timing and gearing.
