Hello all. I'm new to the forum but have been watching for awhile now. I am in the process of rebuilding a blaster motor and noticed something I found rather alarming. The Counter Balance shaft seems to have trenched itself a small area on either half of the case. Has anyone ever seen this? The shaft itself doesnt show any signs on damage. There are a few pics attached. I have rebuilt a few sled and ski motors but not a dirt/street bike engine yet. Any info would be greatly appreciated. Thanks, Ryan
