Actually, the bearings are unique to the individual engine. The bearing sizes are determined during the manufacture of your individual engine. Those numbers are used with a formula to determine which bearing (Pink, brown, etc.) The numbers on the block are combined with the numbers on the crank to determine the correct bearing for the particular journal. The calculations for the balancer journals and the rod journals are similar. It is best explained in this video that is available from this link http://www.venturerider.org/forum/showthread.php?t=84030. $20.00 I ordered them and I can tell you that they are invaluable if you are planning on going into the engine. Damon explains everything in great detail and in a very understandable manner.

 

The videos are of the reassembly of a Vmax engine and the complete rebuild of the Vmax Karber-8-ers. They are quite concise and are altogether about 7 or 8 hours. Of course it is for VMax/1st Gen but I'm guessing that most of the procedures for the 2nd Gen are similar.

 

The best 12 bucks I ever spent was on VR membership. The best 20 bucks was for those videos.

 

If you order them say "Hi" to Damon for me
