Hey guys, I may have goofed, but I'm hoping somebody can shed some light on what happened. I'm in the process of dropping my blaster engine into a hardtail street bike frame and had to modify the front of the engine mount to do so. Basically I just needed to trim down the front mount 13/64 on each side but in the process of doing so, thinned some metal underneath to where a hole formed on each side. I assume that this is just a void in the casting of the front engine mount and doesn't actually go into the working portion of the engine block. If somebody has a block split in half that could verify this I wold greatly appreciate it.
