New bearings installed

Was time to put the new bearings in to freezer and crank case halves to owen. The bearings spent abot a day in the freezer and the crank case halves were cooked for about an hour at 150 degrees in the owen. The workshop manual suggested 100C for removing the bearings but I thought the warmer the case is, the easier it is to get the bearings in. Besides there wasn't anything that could be damaged with that heat.

Main bearings and lay shaft bearings were the easiest as the bearing being at -18C and crank case half being at 150C the bearing went in without any interference. As a matter fact there was even a small clearance for a few seconds which disappeared rather quickly and the bearing didn't come off anymore. At least those should be straight as they literally hit the bottom.

Gearbox main shaft and timing shaft bearings were much harder and I actually had to tap the outer ring with a socket to get them in. They were also in the freezer but they are so small that the case heats them up so quickly. Tapping still requires probably much less force than just having both in room temperature.

Swingarm bearings and seals are still on the table. Those also seemed to be pretty tight but heat gun and cold spray should do. After that I get to real business measuring the crank shaft end float and required shimms. First I need to find the smallest ones since I'm a bit afraid I don't get any float with the original onces.
