Hey everyone i just pulled the head and sump off my RB30ET and i have a couple of Q's 1. Looking at the crank its all been machined and there are drill marks in the bottom and in some of the rods, does this mean the rotating assembly has been balanced? 2. Trying to find out what pistons i have (rods appear to be standard) underneath them they read N1 on one side and BM0031 on the other side of the bottom? 3. Lastly i want to know if its a standard cam or not and im not sure how to tell, i couldnt get the cam seal off but is it behind there on the start of the cam? Cheers, Scott

Pictures! And maybe measure lobe heights on the cam if you have a decent micrometer
