I'm tearing down a cb550f motor. i got tadpit cover, valve cover, the jugs, and the cylinders off, but now it seem like the lower case doesn't want to come apart. I've unloosen and removed all the screws holding the case together. I've been at this for the past two days with no budge... I'd been searching for 2 hrs now and cant find a thread to help demonstrate "how to take the lower case apart?" am i missing something? am i doing something wrong? is it to cold? i couldn't find a prey gap, i even whacked it with a rubber millet and still no give. I'm literately pulling my hair at this point... please shine in, all helps are welcome.
