UNLEASHED POWER! AIR BOX MOD PART 2 (FASTER SCOOTER EPISODE 14)

Affiliate Links to the list of modifications made to this bike:

For baseline settings, a 70MJ was installed after the airbox mod with all of the holes covered up. This would simulate a stock airbox jetting. However, knowing that there is more potential for more horsepower with the holes all opened up, I changed the main jet to a 80MJ. Given such a huge jump in main jet, I should be fine am I right? In fact, with such a huge jump in main jet I will probably run a bit rich and need to lean up the mixture to optimize fuel consumption. But turns out I was wrong!!! Watch the video and let me know what you think. With the new setup, this bike should hit 90kmh (55mph) in a hurry unlike my Honda Ruckus! Stay tuned and subscribe!

Think of engines as an air pump. The more air you can get into the combustion chamber, the more power there is available - with the proper fuel mixture. Our previous modifications showed you how to allow the engine to suck in more air per stroke while the expansion chamber in the exhaust works to keep that air fuel mixture inside the chamber from escaping. Obviously, this power will come at the sacrifice of more noise, poorer fuel mileage, and more engine wear. Therefore always modify your motorcycle at your own discretion based on your own needs.

The 2005 Piaggio Typhoon equipped with the 49cc Hi-Per 2 Engine is now completely unrestricted and performs significantly better than stock for nearly no money. In the previous episodes we demonstrated that the scooter can perform much better with the brass restrictor removed from the Dellorto 17.5 PHVA Carburetor, unlike what others say about the brass restrictor being there to improve performance (which is FALSE). Now, with the bike completely tuned, we have installed the LEO VINCE ZX-R Exhaust. This exhaust is becoming extremely rare and difficult to purchase because it has been discontinued and replaced with the lower model LEO VINCE TT. In the previous episode, we showed you how to install the exhaust and first ride review. Most aftermarket tuning exhaust that comes from Europe has a restrictor installed to comply with government regulations. Their instruction manual states that performance improvements gained from removing the restrictor would render the exhaust illegal for public use. What's the point of getting an aftermarket pipe only to restrict it's performance? With the restrictor removed, we installed the exhaust and showed you one final trick up our sleeves to unleash as much power out of the stock engine as possible before making any extensive engine modifications.

Hope you find this video helpful and please like & subscribe for further scooter tuning videos!

If you want your bike to bury the speedo needle like ours did in Episode 1, subscribe and stay tuned for future episodes. We will show you how to destrict the bike from factory, install the Leo Vince ZXR exhaust, open up the intake, and modify the transmission. Come along with us as we transform this little 50cc scooter from a slow and boring bike to a fast and peppy machine that will do circles around traffic!

Other bikes that shares the same platform/engine includes Vespa, Piaggio, Aprilia, Peugot, Gilera, TPH, Typhoon, LT50, LX50, ET50, Scarabeo, Stalker, Zip, Fly, etc.
