I finished buttoning the bike up tonight after installing the new (Honda, OEM) water pump. I filled the radiator with distilled water, intending to flush it out....and it immediately started leaking out the weep hole.
When I took the old water pump out, it was wedged in there VERY tight - I had to whack it out with a dead blow hammer to get it to come out.
When I put the two new O-rings on the new pump, it slid in there very easily.
Looking at the parts diagrams, the primary candidate for the leak is the large O-ring. I'm pretty sure this did not fold over or kink when I put the new pump in.
Has anyone experienced this? Does the O-ring look undersized in the pictures below?
I guess I will be taking the whole thing apart again tomorrow to try and figure out what is going on. I'm too frustrated and disgusted to do any more with it tonight.
