Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
This is a high quality big bore kit. You must change the ECU, performance exhaust and a larger fuel injector for best performance. I think the quality is on par with the Malossi big bore kit at a lower cost. It really makes a difference to the power the scooter makes.View Detail
I installed it along with a Corso High Camshaft and a 160cc Injector. 。
The acceleration that cannot be experienced with 155cc and the feeling of rapid acceleration even after 80km is very nice. 。 Cylinder and Piston are both well made. 。
I have an impression that it runs pretty well even with OEM ECU. 。
I also like that it is cheaper than otherManufacturer 。
The drivetrain needs to be adjusted, the same as with the 155cc, the balance is worse.View Detail
