Malossi 70cc Big Block Kit (Morini)
Features
Malossi, whose expertise in balancing a vast experience with the latest technology, embraced this new challenge: to bring to the racetrack a fuel injected two stroke engine.
With the new INJECTION TECH range of products a new chapter is written, an answer, the racing world was anticipating, to satisfy the growing number of Malossi Trophy Races for 70cc scooters.

CAST IRON CYLINDER - Technology
- Material: special self-lubricating, wear-resistant, highly refined cast iron alloys, obtained by Shell Moulding gravity die-casting.
- Machining: on numerically controlled high precision machine tools.
- Recalculated heat exchange surfaces.
- Exhaust and transfer ports designed and tested for maximum thermodynamic performance.
- Shape and surface texture dimensional checks.
- Cylinder and piston selected for a 100% fit of 0.010-0.005 mm.
- Checking of all the seals carried out.

ALUMINIUM CYLINDER - Technology
- Cylinders obtained by gravity die-casting in permanent steel moulds.
- Material: hardened and tempered high silicon content primary aluminium alloy.
- Machining: on numerically controlled high precision machine tools.
- Cylinder liner with silicon carbide metal-spray coating on a galvanic nickel matrix, cross-honed with passes with diamonds for very tight tolerances.
- Heat exchange surfaces recalculated.
- Exhaust and transfer ports designed and tested for maximum thermodynamic performance.
- Shape and surface texture dimensional checks.
- Cylinder and piston selected for a fit of 0.010-0.005 mm.
- Checking of all the seals carried out.

PISTON
- Material: special aluminium alloy with high silicon content and low thermal expansion.
- Machining: on numerically controlled machine tools.
- Lightened and strengthened.
- Heat exchange surfaces increased.

PISTON RINGS
- Rings in very strong modular cast iron with ground, wear-resistant, hard chrome metal-spray coating on the contact surface.

HEAD
- Material: special die-cast aluminium alloy.
- Geometry of heat exchange surfaces recalculated and increased (air-cooled models).
- Cooling circuit sections and paths recalculated and resized (liquid-cooled models).
- Machining: numerically controlled high precision machines with diamond tools.
- Surface rust prevention treatment.

NOTICE:
FOR THE PROPER WORKING OF THE KIT IT IS ABSOLUTELY NECESSARY TO USE THE TC UNIT SUPPLIED IN THE KIT AND TO SUBSTITUTE THE PRIMARY GEARS WITH THE HTQ MALOSSI ONE, TOGETHER WITH THE ORIGINAL EXHAUST SYSTEM OR THE MALOSSI ONE.

What I was looking for. November 14, 2010
Reviewer: Russ from Sacramento, CA United States  
Greatly improved acceleration and top speed, especially with a passenger on the back! I put in the VL12 reeds with stock stuffer and Malossi gears at the same time for a great result.

MORE power. July 19, 2010
Reviewer: Tim Klumper from Winnipeg, MB Canada  
What can be said that hasnt been said before about a BBK.  For those that want or need more torque and top end speed this is the first step that you will need to take in order to reach that goal.  One of the best upgrades you can do to your SR50.

Fairly easy to install, it can be done easily in an afternoon for those with a bit of mechanical aptitude.  Take your time READ the instruction over and over again BEFORE you start the upgrade.  Watch the C clips on the Piston Wrist Pin as they will fly on you and the Piston Rings are VERY delicate so take care when installing them.

To get the most out of this upgrade you should also look at getting your Primary Gears upgrade with a Malossi Gear-up kit p/n 6711297. This will give you more top end speed.

Other upgrades that will help and/or are needed include
VL12 Reed Block for the Morini crowd
HGT Regulator
Malossi Special belt
Malossi Air Filter
Malossi Multivar
