High Comp Piston for the Stock Bore on the Grom
About quality and texture: I am happy with the quality of the 52.4mm high compression piston kit from SP Takegawa. Material used for the piston is aluminium and forging is used for the manufacturing process. About the feeling of use: This piston kit allows for a small power increase without compromising the reliablity of the engine and needs much less supporting products when compared to installing a big bore kit. Products to buy together: A fuel injection controller FI-CON 2 would also be desirable to purchase alongside the high compression kit to control the changes in fuelling required for successful running of the engine. Difficulty of installation: The process to install takes about 2 hours. After disassembling the top end, clean the base gasket off and hone the cylinder before installing the new piston. A little difficult to do. Cost performance and comparison with other products: High cost but you are getting a piston manufactured to a high standard and from a quality material just like the Kitaco Neo 164cc and 181cc pistons and at similar pricing. About shipping and packaging: Sea frieght is my preferred method of shipping due to the lower cost and it is fantastic that it has returned as an option once again so I can put my money toward parts and not high shipping costs. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged. Any concerns, cautions, or advice when purchasing: If you are needing more than just the piston for your repairs then Shift Up offer a cylinder with oil ports to allow easy connection of an oil cooler.
