Kolben -LAMBRETTA- Lambretta GP, SX, TV 200 ccm - 66.0mm

I fit this onto the BGM 60mm stroke crank with a 110mm con-rod. Before fitting we realised that the area where the con-rod attaches via the pin and small end inside the piston, it was lacking in access for oil to reach the small end so we had to drill two small holes up inside the piston at either side of the gudgeon pin and small-end for safety. This is something the manufacturer should look at. Apart from that the piston kit is good.
