    New engine- what to do?

    I rebuilt my gs1000 and put in a wiseco 1085 kit.
    I checked the compression cold before I put the
    pipes and carbs on (I know you are supposed to check it hot
    but I just wanted to get an idea before I put it all back together).
    Anyway, I got 135,125,118 and 135 psi.

    On 1 and 4 I got 135psi on 3 turns of the engine and it took
    5 turns to get the 125 and 118psi on 2 and 3 cylinders.

    I put about half a cap full of oil in the 2 &3 and rechecked
    and got 155psi after 3 turns of the engine.

    My ring gaps are within range, could I be getting low readings
    on these cylinder just because I have a fresh hone and my rings haven't
    seated yet?

    Also I remembered after I put oil in them, that most people recommend
    dry cylinders for break -in. Won't most of the excess oil burn off
    when I fire it up? Or should I pull the head and wipe down the cylinders
    to try to get it dry as possible? (I'd really rather not do this unless
    it's really necessary).

    Thanks in advance

      Low readings cause its not broken-in yet, pull the plugs crank it for a few seconds with some rags over the plug holes so oil won't get all over, this will pump most of the oil out, and leave enough to lube it while trying to get it going, dry cylinders are NOT a good thing on a new motor, you just dont want to much oil or gas in the cylinders or you may wash the rings out

          I'll give the rag thing a try.
          Some people suggest dry cylinders so that the
          rings seat better against the freshly honed cylinders.

          Thanks for the hint.
