Have you googled derestricting 50cc scooter and read through the information there to see what applies to your scooter? If not I would start there. I couldn't find my exact scooter, but the restrictions put in place seem to be about the same from various manufacturers. Also watch out, depending on where you live going faster than 30 mph where I live makes it a motorcycle. Hasn't stopped me just an FYI.

Well, if its the same as older bikes, which it likely is, then you may have restrictions in the variator, intake, exhaust, and possibly the CDI.
Variator restrictions tend to be washers or ahims placed in a 2ay that prevents the belt from full travel. Easy to remove.
Intake restrictions tend to Be in the box, if you open the air flow you need to add fuel as well, or risk burning the piston.
Exhaust restricted toons are either a washer or plug welded to the manifold end of the header pipe, or a type of catylaic converter. The washer can be ground out the "converter" can normally be punched. Again, if you allow more air out, it will pull more air in, and need more fuel.
The cdi restrictions will limit RPM and some are even wired to the speedometer to limit top speed. At tines, with certain bikes, its as easy as sniping the correct wire. Others have to be replaces with unlimited units.
What country are you in that still sells new two stroke bikes? I'd kill to have new two strokes like that here, but it ain't gonna happen.

Good question! certainly a dying breed (almost as if obsolete) though the only “New” 2-strokes I really see now in the states are the Morini based TGB’s. As others have already mentioned some posting some pics of your new scoot would certainly help others here to get you in the right direction. |

If you can here the revs drop I would think you have a electronic rev limiter in the CDI among other types. Mechanical limiters such as those in the variator slow you down due to gearing. Limiters in the exhaust choke the motor so it can't rev to high. Limiters in the intake also choke restrict the motor mechanically. Neither would slow you down going down hill, a rev limiter would see a high rpm by counting and turn off the spark. Take a few pictures of the CDI box, might be the same as other Chinese scooters and you can get an aftermarket with no limiter.

Before we much farther if you deristrict that very smart new scoot you will invalidate the warranty are you OK
on that.

You will need to Swap out the Cdi Australia Law like the speed limited.
I helped out another Australian with Yamaha Prebug build .
He had a restricted CDI stock (Yamahas Zumas in the states CDIs are unlimited)
He swapped to a athena kit and added gears and a leo vince pipe
He was frustrated had a ton of power and it would just cut out well below 70 kms even going down hill.
Once he snipped the wire on the cdi He added 25 km .
He was pulled over for going above 90kms .
The Police man was impressed gave him a warning as long as he told him how he could build something that could rip like that .
Genuine scooters make the Buddy and roughhouse here in the staes that are minnarelli based 2 strokes.

That is the biggest problem with restricted 50's to slow to stay out of trouble.
Most of restricted cdi's cut out and knock 20% off your peak rpms .
Being in Australia you pay alot for shipping to get parts so group your purchases If you find a derestricted cdi add some jets for your stock carb since when you fully derestrict the engine you may have to upjet the carb to keep safe engine temps at the higher rpms.
Just buy the same jets in a range 3-4 sizes in between your current jet and a jet around 20 % higher than you have now .
To dial in the jets
Start big and work your way down take notes on top speed when you get 2 jets that have the highest speed default to the bigger of the 2 jets for safety you an also plug chop to double check your chosen jet.
If you really get the upgrade bug .
The next step up is to go to a sport 70 cc kit and expansion the jets range above will still work with stock carb you will just need to add on some stiffer clutch springs and a range of 1-2 gram lighter roller weights to your order so that you can rebalance the transmission to the the new power band .

We’re still not getting to the point of what kind of engine this is based off of so he can search for the proper parts... to me it looks to be a Minerelli based (1e40qmb) though maybe someone has a better eye than me.

Matty
On the Cvt he has the code that shows it is a minnarelli .
PE40qmb
You are right It would be terrible to order the wrong parts .
As long as he posts pictures up of the cdi we can keep him from ordering the wrong one .
