Overheating possibly Mech Seal?
Took a long trip to NY on the bike and she rode great with the exception of it pegging at the last white line on the temp gauge on the way home, luckily the fan stayed on most of the ride home so I never seen it get to the red. I did notice on the way up, the bottom swing arm up was a little wet. I'm thinking it was coolant but didn't think anything of it at the time. Also the back of the rear cylinder had what I thought was oil. I read that if oil is leaking from the rear weep hole it was the spark plug tube. I luckily had the spark plug tube o-rings on hand so I swapped them out once I got to where I was going, but still seen the rear part of the engine wet on the way home. Is it possible if the mechanical seal is bad, it allows coolant to escape out of the same weep hole? I'm thinking my issue is here as I got the 89 accord fail safe thermostat and swapped that in last night and bled the system but she was still getting too hot idling. So I'm thinking its something with the impeller/mech seal. Any thoughts of what to try. Nothing shows a leak anywhere else but the rear cylinder under the manifold and swing arm.
