I guess this 90cc NARAKU kit must work well. It would be much more professional of the seller to specify that you absolutely need a specific ECU for this new displacement when installing it on a 50cc! Otherwise, it just doesn't work, and there's no one to help you! When I asked them for help, they told me to go and see a garage. That's cool, but not everyone can afford to go to a garage. So I don't think it's right.

Cylinder and piston good quality but rings unfortunately not. After 150 km of mileage the gap of the rings after inserting into the cylinder was 3.2 mm Yes does not lie. The engine did not smoke but did not have its power. The solution to this was to put on rings made professionally from good quality materials. The cored rings lasted 13,000 km in a Chinese scooter. In my opinion, it is worth it to buy the made-up rings for 40 PLN than to take apart the engine every 2 weeks.

Brok on piston and channels price very good for the quality of the product as much as possible I recommend along with the head 90cm3 may appear collision suggests to collect some material from the piston or house a thicker gasket

when assembling the head and cylinder collision occurs you have to give a thicker gasket pog head, I personally rolled a piston for this amount I do not complain
