68,8cc Bore Up Kit (46mm)

It has more torque than a 50cc and is less likely to stall when climbing hills.

If you don't use a dedicated Bore up Chamber, the RPM will hit the head at about 9000.

Because the CylinderSkirt part is very thin, the durability is quite inferior, but it lasted about 2 years in the town riding & mountain pass Touring Main.

To be frank, it's a copy of CHARMO... (Polish)

По цене данный товар удовлетворителен. доставка вышла очень быстрая, полтора месяца морским путем. К сожалению, плюсы закончились. И есть огромные минусы:1. Нет окон на поршне. Мы выигрываем в ресурсе но проигрываем в мощности. Но это не логично из-за второго пункта2. Очень тонкая гильза. По теории, чем тоньше гильза, тем меньше ресурса у двигателя. Тут она 2мм. Это очень мало. В связи с этим, полнейшая несбалансированность вкупе с ресурсным но непроизводительным поршнем. Если бы в оршне были окна, то оба минуса я бы опустил. Но нет3. Отвратительная отливка. О полированных каналах даже не думайте. тут все очень плохо. На фото приложу доказательство4. Фазы упали. По сравнению со стоковым цилиндром, на месте только выпускное окно. Продувочное и впускное опустились вниз. Честно говоря, за такую цену я остался не довольным...For the price of this product is satisfactory. Delivery was very fast, one and a half months by sea. Unfortunately, the pluses are over. And there are huge cons:1. There are no windows on the piston. We win in the resource but lose in power. But this is not logical due to the second point2. Very thin sleeve. In theory, the thinner the liner, the less resource the engine has. Here she is 2mm. This is very small. In this regard, a complete imbalance, coupled with a resource but unproductive piston. If there were windows in the orchard, then I would lower both minuses. But no3. Disgusting casting. Don't even think about polished channels. everything is very bad here. I’ll attach the proof in the photo4. The phases have fallen. Compared to the stock cylinder, only the exhaust window is in place. The purge and inlet sank down.Honestly, for this price I was not satisfied ...translated by google translate

The seller sent everything quickly, put everything in order, the track was tracked, the quality of the spare parts was at the highest level, and everything was perfect, thank you very much to that seller, I advise you to order from this distributor!

I did not think that I could do power up so easily.
You can convert on the car without dropping Engine.
Because the exhaust port is low Cylinder, it seems that it does not turn to high rotation if it is attached with a pump. By scraping to the same height as OEMCylinder, 13000 rotations could be confirmed with the attached Gasket.
I think that break-in driving is necessary.
I turned VANVAN up to the Red zone as to how long it will be from the initial bombing but there was no problem.
I switched Carburetor from OEM to PE 24, and acceleration was further improved. I can not return to NORMAL anymore.
Needless to say, 80 ccEngine replacement is the quickest as long as you want to speed up N Tribe.
If you enjoy the pleasures to ride, the fun of doing it I think that Taiwan Cylinder is a white White choice.

I have not gotten there yet, but slow Torque is out and it has Power
It seems that it will turn firmly upward, but I feel that it does not seem to be above in relation to the port
Performance was good, but I felt something strange when I saw the attached Exhaust Gasket
Sure enough Gasket does not suit me at the interval of Stud bolt bother with funny things
I processed the Exhaust System side Gasket was not Exactly so it was crushed
There seems to be little leakage of exhaust
