9.10) Technical Specification (within the engine seal) for ROTAX kart engine 125 Mini MAX (10 kW):
For the engine configuration 125 Mini MAX, everything that is not specified below, latest technical regulation 2013 for engine configuration 125 Junior MAX is valid.
It is the responsibility of the competitor to check his equipment (all componentsoutside the engine seal and mentioned below), to assure that his equipment is in line with the technical specification below!

9.10.1) Squish gap:

a) 125 Mini MAX 1,20-1,80mm

For the United States:

-125 Mini Max 2.80 mm minimum

To achieve the defined squish gap, a spacer (ROTAX part no. 626 420), plus the different required base gaskets must be used. The squish gap must be measured with a certified slide gauge and by using a 3 mm tin wire. The crankshaft must be turned by hand slowly over TDC (top dead center) to squeeze the tin wire.
