    I'm looking to do this with my 1980 mr50. Where did you buy the oil seals set? And which bearings. I think it's the same engine

    Can be dangerous to flatten a RD M piston. The top of the piston is calculated to stands against ignision pressure. It can blow a hole in the piston, damage the new coating and presses metal particles into the cylinder head. DX can reach 11000 rpm, which brings a lot of heat. Pressure and heat. DX need a proper piston.

      You raise a good point. It ended up not working anyway with this piston. More on that on the next episode.

    the crank bearing on the flywheel side was very slack fit ?? ,, heat alone woldnt have made it expand enough for the crank to just slip in , vertically split cases like the rd and fs1e normaly require this side to be pulled into the bearing with a puller .

    • @VintageGarageYT
      @VintageGarageYT  11 หลายเดือนก่อน +1

      They have been like this for both the fs1 and the Rd. Never had an issue with them like this.
      Also I heat up the cases, but the bearings themselves have been in the freezer for a couple of days. So the cases expand and the bearing shrinks enough to have it this way. Worked everytime so far.
