Porting Tools: Cylinder wall scratch & scoring - Stopped in 5 Easy Steps

Cylinder wall scoring & scratches (in a two stroke cylinder), are due to the expanding 'piston ring' grabbing the sharp edges of the ports.

A set of tools and cutting grit (Port Toolz™) have been designed specifically for converting the sharp port edges into 'load bearing surfaces'.

The tools shown in this video can be purchased for € 20 from

Transport costs range from € 3 to € 8 depending upon your choice of service

Carburettor tuning software is also available for € 8, when purchased with the porting tools.
