The Dobeck Electronic Jet Kit is a Plug and Play installation and only takes minutes to install. It offers a full range tune ability. 

Use the Camshaft with either the stock bore or our 186cc Big Bore Kit.  Similar specifications as the the DCR Cam and is about 1/3rd of the the price!  As with all our cams, the quality is also exceptional and not a regrind OEM cam.

This is the biggest bore kit on the market! The all aluminum ceramic coated cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). This new big bore kit will provide the extra power to make your new Grom a lot more fun to ride! High quality parts and requires no machining to the cases.

There are no installation instructions, but if you can replace your piston, you can install this bore kit as the parts are installed in the same manner as the OEM parts. However, its recommended that a professional install this kit.
