2006 rm250 rind end gap

I just got my cylinder re niked and a new piston and rings ready to instal. What should the ring end gap be? The manual has a service limit specified at .8 mm but no starting point? Should I not need to file them at all?

Maximum of 20 thousandths, ideal is 14 to 17. Set the top ring 2 thousandths tighter to prevent ring flutter. Hope this helps

could you translatethis to mm?

how does the top ring flutter? honda 250 uses 2 identical gaps, why not suki?
