Help please, I do not know what to do.

I used to upgrade my scooter and had the following improvements:
- Unrestricted CDI, unrestricted variator boss;
- 72 cc Naraku Kit: https://www.racing-planet.de/cylinder-kit-naraku-v2-72cc-for-gy6-kymco-50cc-2v-p-101917-1.html?backcPathco=16&cPath=26_11792;
- Malossi Multivar 2000 Variator with 6g rollers;
- Secondary transmission gear up kit 17/49: https://www.racing-planet.de/secondary-transmission-gear-up-kit-top-racing-18-17-49-for-china-kymco-4-stroke-p-260390-1.html?backcPathco=5&cPath=26_11792;
- Main Jet 82.

The scooter was fine, being able to reach up to 75kmh.
However, it pulled up really slow and didn't do much good inside the city.
And, due to the high compression, the kick-start wouldn't work.

So, I installed an 80cc kit from Airsal: https://www.racing-planet.de/cylinder-kit-airsal-sport-813cc-50mm-for-139qmb-gy6-50cc-kymco-50-4-stroke-p-270391-1.html?backcPathco=16&cPath=26_11792.

After this upgrade, the scooter was pulling even slower and the top speed dropped to 65kmh.
Why is that?

I understand this kit has a lower compression.
It is true that now I can kick start the scooter.

After the 80cc kit, I installed a 19 carburetor with 33 pilot jet and 85 main jet: https://www.racing-planet.de/carburetor-replacement-for-4-stroke-139qmb-qma-p-98831-1.html?backcPathco=16&cPath=26_11792.

It was a bit better.

Then, I just went back to the stock secondary gear kit.

Now:
- the scooter pulls a bit better;
- maximum speed is 65 kmh and it revs very high, the scooter actually trembles at maximum speed;
- consumption is 3.8 litres per 100 km (that's 61 mpg).

I wanted to install a sports air filter: https://www.racing-planet.de/air-filter-air-system-metal-gauze-filter-38mm-straight-version-blue-shield-p-98596-1.html?backcPathco=16&cPath=26_11792.

But my mechanic said it won't do any good for a 4 stroke scooter.

Please help, what should I do. I am desperate.
Thanks,
Cristian.

Dear All,

I am the very happy owner of a Kymco Like 50 4T. Basically, it is the same engine as the Agility. There is no dedicated forum thread for my scooter, so I am posting here.

I have made several mods:
- Racing CDI and variator bushing removed (complete derestriction);
- Naraku 70cc kit;
- Optimized Main Jet;
- Malossi Multivar 2000 Variator (6g rollers, white spring);
- Secondary Transmission Kit (Top Racing );
- Oval and bigger mirrors;
- Wind-shield;
- I have tried to install racing smaller springs for my clutch, but the engine was over revving and in the end I wend back to the factory springs.

Well, before installing the 70cc kit, the mechanic warned my that the kick-start would be much stiffer.
On cold mornings (I was riding the scooter all winter long as there was no snow in Romania), I would try to kick start the engine.
It was extremely stiff. And in the end, it just broke.
The mechanic told me that I need to buy a new kick-start set. Half-moon and the other piece which I do not know how to translate in English.

I am attaching a photo.

Could anyone advise me where to buy from? And what to buy?
In Romania I can barely find cheap, chinese parts.

Thank you and best regards,
Cristian.

Hello everybody,

I bought a Kymco Like 50 4 stroke in March 2017, brand new. I haven't found a dedicated forum thread for my scooter, so I am asking my questions here.

My scooter is restricted, most likely the CDI is restricted as I do not exceed 45 kmh even when riding down hill.

What I want to obtain is:
- 70, maximum 80, kmh top speed;
- a little bit more power when moving from stand still or when passing small cars.

As I do not want to spend a lot, while I know nothing about scooters, I was thinking of buying a derestricted CDI and a 70cc kit.

Could someone recommend me what to buy?

I am a plain financial analyst, wearing a suit while riding the scooter and taking the subway when it rains.

Thank you,
Cristian.
