Thank you for the huge jump in subscriptions! I certainly don’t know everything about scooters so please share your knowledge with me but I will try my best to document my modifications so you can do the same to your bike.
With all the engine modifications complete and put behind us, I am excited to begin transmission tuning. The factory transmission is designed for the perfect balance between fuel consumption, engine longevity, and performance. For my application, however, what I need it maximum performance at the sacrifice of more fuel – (It’s a 50cc bike and fuel consumption is frankly the least of my concern!) So with that said, most manufacturer install stock roller weights that are far too heavy. It turns out Piaggio uses 6.5g stock roller weights in this 2005 Piaggio Typhoon. Leo Vince supplies 5.8g weights so might as well give it a try before I purchase even lighter roller weights! Piaggio report this engine makes peak horsepower at 9500RPM. With that said however, Leo Vince never really supplied any information at which optimal RPM this expansion chamber exhaust pipe is designed for. However, it’s elongated shape and reviews on the internet tends to suggest this pipe is made for the higher 9000+RPM. This video will show you how to install the Leo Vince 5.8G roller weights into the transmission. Hope you enjoy!
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. Check out my other videos in the meantime to make your 50cc scooter much more useful and fun to ride in the city!
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.
