Cylinder Metrakit SP3 70cc Minarelli AM6

From Metrakit come the new METRAKIT SP 3 cylinders!!!
The new Mid-Race cylinder, maintaining its Metrakit line, continues with exhaust outlets with boosters.
They have made some differences in the distribution; the new “SP 3” consists of 5 transfer ports that are somewhat larger than in the previous version, in order to improve both power range and torque compared to the old one.
As a new feature, Metrakit cylinders are now offered with Vertex pistons with anti-wear graphite, fitted with 1 ring to achieve maximum performance.
Truncated cone-shaped cylinder head RV 14/1 for clean and perfect compression.
A true cylinder gem that should be combined with competition components.

It is recommended to install with Metrakit SP3 or Voca Rookie exhaust, a 24 or 28 flat slide carburetor, and an Iridium spark plug

It is advisable, when installing this cylinder, to change the crankshaft and use a more reinforced one.
