70cc Minarelli Vertical Engine

**Built-To-Order. Please email and confirm delivery ETA before ordering** Bigger, Better, Badder, Faster. These are absolute screamers! They like high RPMs to make big HP.  This 70cc hybrid utilizes imported specialized cylinders specifically built for performance in mind, it has fantastic proper port timing. They use a single flat reed valve that flows straight down into the case. Combined with a custom billet spacer plate and intake design, you get nearly all the benefits of a case reed all with the stock case.  OPTIONAL: Fully reworked bottom end, port matched transfers, ported cylinder ports. OPTIONAL: Upgraded cranks seals to use larger Viton seals. Meant to last and never fail again. SPECIFICATIONS Cylinder: OEM+ cast Iron cylinder *appearance may vary* Crank: Long Rod Trued and Balanced Exhaust Spacing: 48mm Flange Spark Plug: NGK BR8HS, BR9HS Intake: Mikuni VM20 flange mount  NOTE: The stock main jet is much too small.

We highly recommend upgrading the head to get proper cooling these motors need. SP CNC Head
