Re: Cylinder Kit - BGM or SIP GS
Harry's piston 68.0 and 68.5 uses wire rings ( Rik) from an old spec of cr250 honda, they are 1.2mm thick and the pistons were made to suit these rings, all the rest use cast rings.... which will not stand a wide exhaust, max around 44mm, approx 64%, wire rings allow wider approx 46mm, 67% for road ...

Re: barlow stage four set ups
The piston Harry uses is 68.0mm Taiwanese high silicone content, has 1.2mm thick Rik wire rings ( from CR250 Honda ) this allows a very wide exhaust port to be made 44 to 45 mm is reliable (66%), the 218cc version has his own 60mm crank that closes the inlet at the original closing point, approx 55 ...
