    Resleeving & sleeve sealer

    Is there any idea to coat cylinder sleeves before installation to block for example VHT copper coat?
    Purpose would be to obtain better heat transfer from sleeve to block.

    When cold the interface is an interference fit. Anything coated on the cylinder would get scrapped off during installation.

      When the block is heated and sleeves freezed the sleeves drop in.

        I don't know man, pretty sure no manufacturer bothers with thermal paste or the like in that application. There must be a reason (other than maybe money). I think most of the heat goes out through the head not the cylinders, so even if there was better heat transfer with the paste, I don't think it would have much if any affect.

          Ok. I?m resleeving GS 1150 block with GSXR 1127 sleeves. It?s going to get Hayabusa pistons.
          1360 cc engine with about 10:1 comp is going to make a lot of heat.

            The sleeves need to go in with nothing between the metal to metal, interference fit. You will need a big oil cooler. Electric fans on it will help also if your climate gets hot in the summer.

              Ok, thanks! It?s going to get a big cooler with stat. I have 1327cc supercharged GS which is running with E85. It was sometimes difficult to get the engine in normal running temperature.
              That other bike I?m building is going to run with gasoline, so the heat can be issue in summer time.
