    what piston to wall clearance for Wiseco?

    Hi,
    I have some 80mm Wisecos and the matching Bigblock for my GS1100. What clearance should I have it honed to? Actually it is already honed, I just want to double check. This thing is going to be a (pretty wicked) street only engine, no NOS, no turbo.
    So what piston to wall and what ring gaps do you run under which conditions. I found instruction for the ring gap on Wiseco's page, but nothing about the wall clearance.

    Give Wiseco a call, I'm sure they can tell you.

      Ring gap: 0.012 ? 0.015 (mfgs. changed ring gap to 0.020 the start of 2006, not sure how old your parts are.)
      Piston to sleeve: 0.0025 ? 0.003?

      Hope this helps.
