the crank looks like swiss cheese lol, looks like they had to take alot out. that is a lancourts cylinder, i think they are the best in the U.K so i am sure it will be right but i am going to check it any way. crank not welded i dont think it needs it, time will tell. the gasket it a mitaka, no idea of the thickness i will use it for running in, then lift the head to check every thing and set the squish, how is yours going dave, is it together yet
