Zenoah G240-23 cc Falcon3 Tuning engine

Meanwhile, the Zenoah engines in terms of material development have become so good that we have adjusted the tuning accordingly. It is no longer possible to raise only one outlet and lower the cylinder. Fuel consumption has also become an important factor, and more importantly, it still has the same power even after many hours of use!

The smooth power band is at your demand at any speed, at any RPM! We assemble all parts with great precision and use only TPS high quality gaskets. This way you get a reliable and fuel economical power engine that delivers when you need it! The Falcon3 tuning has been copied a lot, but the knowledge and precision is the X-factor that distinguishes the real Falcon3 from the rest!

What do we do?

• Straightening crank case
• Balancing and grinding crankshaft
• Machining the flywheel
• Modify piston
• Modify cylinder
• TPS tuning gaskets
• Professionally build by experts

This all combined gives the extra buzz what others do not have. We give you the guarantee that this engine will not disappoint you. You'll be amazed by the smooth performance which is always there, this all combined with economic fuel consumption.

We recommend for optimal use; PSR-2 Race Oil and TPS™ Air Filter Systems. This motor is suitable for all models using a BWS, Dynamic, LOSI, Zenoah, HPI Fuelie or CY engine.

Engine running in:

• 1) Use 1:25 fuel mixture, 40 cc good quality 2-stroke oil on one litre 98 Octane fuel
• 2) Carb needles both 1 1/4 turn open
• 3) Start first time let it run at idle for 2 minutes until is had normal temperature
• 4) Run first tank of fuel normal but without reaching high speed, this will take approx 45 minutes
• 5) Let it completely cool down
• 6) Run second tank of fuel, now start reaching high speed shortly, this will take approx 40 minutes
• 7) Let it completely cool down
• 8) Visual check in exhaust port, check for leakage
• 9) Third tank drive it like you normal would do, but still reaching high speed shortly, but building, this will take approx 35 minutes
