By installing the FI-CON TYPE-e (Injection Controller) at the same time, you can achieve a torquey output characteristic that is different from stock. The cylinder is the same as the stock steel cylinder. Without sports camshaft is for those who have sports camshaft only and want to upgrade to e stage.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Just completed the installation of the Special Parts Takegawa 143cc big bore piston and cylinder kit. Inspecting the kit on arrival I was very happy to see the kit included everything I needed to carry out the installation but it would be nice if installation instructions would come in english or at least be able download english instructions from their website. The quality of the parts is excellent as you can always expect from Special Parts Takegawa. After researching a how to guide on the installation the job was not difficult provided you have the right tools. I will review again in a few months after I have put some kilometers on the motor to submit my thoughts on this upgrade.View Detail
