ok I did the radiator flush and rechecked the grounds... I'm at a loss. it acts as if it needs more flowing through it. if i'm on it it warms if I just cruise it runs warm but not as warm and it will cool off to that point even if it was hotter (running hard). so it's got to be a flow issue?? the radiator was flowing fine. (hose on full blast and it just dumped out the bottom!!) I assume that means there isn't anything blocking. I can't find any warm/cool spots either. anything else?
