Sorry for the poor video and audio in this episode. The camera really crapped out on me this time! For this episode, we will get some baseline settings first AFTER the airbox modification in episode 11. If the tape is sealing the holes as expected, no jetting change should be required because the airbox should perform exactly the same as stock. Regardless I was running slightly lean previously so I installed a 70MJ - just a tad richer for safety's sakes. Once we get a correct baseline setting, we can tune the carburetor to make use of the extra oxygen sucked in from the airbox mod and make more power. I am super curious how much more power this engine already makes with just a restrictor removal/muffler install. I can't imagine how much MORE power it will make with the airbox mod and afterwards some final CVT tuning. This bike should hit 90kmh (55mph) no problem 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.

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. - Авто та транспорт
Hello you put 70 main jet and how many turn you did to the air and for the needle thank you for answer
I ended up with a 82 main jet here where I live about 700m above sea level/low humidity, and I don't exactly remember the setting for the idle mix screw. Needle was one position lower than original. Check out my other videos for specific details!
Which exhaust would you recommend for a Yamaha Aerox 2006? I just bought it cheap and tuning it for speed and acceleration but it's my first scooter and I don't know what to do
MrJestersky98 it really depends how much you want to spend. Personally I would think the airbox mod and roller weights made the most improvement. In regards to exhaust I really like Leo Vince ZX and ZXR as they come complete with beautiful welds, clutch springs, and lighter roller weights. I especially like how they hide the muffler mount behind the expansion chamber when most companies have it exposed. Their prices are reasonable as well
I'm looking for something at 200$ or below, I'm planning on tuning my scooter like you did to the best of my ability but I'm new to vehicles and tuning
Thank you for your help and nice series
MrJestersky98 instead of investing in an exhaust for 200$, for the least amount of money I would do the airbox mod in my series, buy 10$ of jets to tune, and then 6$ on a tach, and about 10$ on lighter roller weights and you would achieve 70-80% of the improvements you saw in my video. You can find the items I bought in the links in my description but it is for the piaggio typhoon
Check Yasuni R mate.
your scooter reaches top rpm so fast :O I have so many problems with a chinese minarelli copy of mine... I am going to try your exhaust box mod today, but right now the bike is REALLY slow to get up in revs. I have tried changing rollers which just set the RPMs high on takeoff, but then they would drop off :( any ideas?
I would try to find the problems before doing any modification. Is your transmission clean and free of grease? What is the weight of your current roller weights? What RPM do you see with those weights? How much does the RPM fluctuate during acceleration all the way up to max speed?
my tachometer unfortunately broke (cheap china one like yours) right now i have 5.5g rollers in, although it came with 5.2g, so im putting in 5.0 today seeing how well it works. My transmission is clean and problem free. It is an engine/carb problem i am 100% sure of that :)
FIFTYmil the rpm doesnt fluctuate either, except when launching ? Also the bike changes sound when it gets hot, there is like a pinging Sound coming when i give it revs
Perhaps your carburetor needs a bit of a tuneup/tuning!
If the RPM is constant, but only fluctuates on launch - that seems more like a transmission slipping issue as a likely cause.
