Preparing a two-stroke engine involves worrying about improving the top end of the engine and more particularly the piston, its segment or segments without forgetting the circlips and the piston pin which can seize in the connecting rod foot. How to prepare your piston to optimize the operation of the segment by modifying the segment groove and the segment itself on several important points to avoid any alteration of the cylinder, seizure or engine tightening. Find out how to avoid tightening your two-stroke engine due to ignorance of the very simple modifications to be made, which would be a shame... so we will tell you the things to do and especially not to do to boost the performance of your 2-stroke engine for ever more power and torque at all engine speeds. We will talk about the forged piston, the cast piston, the segmentation and the different types of L and rectangular segments, single-segment (monosegment), two-segment (bisegment), beryllium pistons, the flat piston, the convex piston, the conical piston as well as the influence of the piston shape on the squish band of the cylinder head; the control and measurement of the clearance at the segment cut in order to check the gap between the two beaks of the segment and ensure that it does not cause a tightening or seizure during the expansion of the segment during the heating of the piston and the cylinder.
