Zero Clearance Side Seals

[afgmoto1978]

Barry,

Neat idea, but what about Apex seal clearance, assuming you had more clearance at the apex seal (two faces) you would see unwanted binding at the side seal from the apex seal rotating at the point of peak combustion pressure. Only one way to find out, and that's to test it out.

If money was no object, zero clearance on everything after Nikasil coating, or something of similar low friction properties. Ceramic coating......

i was thinking the same. cant really avoid it(by cutting out more space to move) and keep the seal tight, so if theres any rotation of the corner seal it may cause binding and eventually wear the broad surface of the side seals.
