What ring gap?

[fish_19]

I have an 82 250r 70mm bore. I bought a new piston and discovered I bought a 71mm piston by mistake. So I figured I would bore it to fit the new piston. However. What do I need to set me ring gap to and is there any other things I need to change? The shop asked me what my ring gap and piston stroke (or something like that) needed to be. Any help?

Top of page 2 (The page is for a Harley, but the chart is the same on my 200x weisco 10.25x1 high compression (66mm bore = 2.598 In X .004 (Top ring) = 0.01 ring gap, bottom 0.0129). Yours should be 0.011 for the top and 0.0139 for the bottom with a 71mm bore. Bottom is always larger to prevent ring float.
