    Hey guys, I've come back for more help. After several months, I'm finally in a position where I can tear into the engine and troubleshoot a severe coolant leak on a freshly rebuilt, triple-bypassed 1982 GL500 that had only ran long enough to begin the tuning process. here's that last post if...

    Finally got the bike started after a year of rebuilding. I'll have pictures soon. She looks great. Bike ran before the teardown. Runs now too, but was spewing oil out the oil pressure switch. It is new. Bought from 4into1 but something doesn't seem right to me. After pulling the rubber...

    The coolant pipe on my 1980 custom had a split, horizontally, that was leaking water and coolant down the side of the engine. I understand the o-ring is the normal issue and I believe the last owner changed o-ring hoping to solve the issue. So, after purchasing a used pipe from ebay and...

    I'm in the process of restoring a 79 CX500 and while changing the oil I noticed it was milky. After some research I saw it would most likely be the mechanical seal. I used shep's method to replace it. The one that was in there was in bad condition, and so I left everything sit for a few days and...

    Hello everyone, I have a 1981 GL500 that's been giving me a headache because of a coolant leak and I am looking for expert advice (and maybe piece of mind) that this problem can be fixed... Here is a little bit of background on the motorcycle... It started with a small drip out of the weep...

    My '81 GL500 is "weeping" coolant from that typical place, at the back of the motor. Not a lot, so I am not sure if this is allowable. I read on the Triple By-pass page (please don't tell me I have to do that!) that the weep hole is there to allow spillover to weep out, and this is stated as if...

    Hello everyone I am very new to these forums and I hope I am posting in the right section. I am about to purchase a 1979 Honda Cx500 Custom from one of my very close friend's family friend.

    The answers to these questions may be posted somewhere else, but I couldn't find them, so please forgive me if they are. A little background first. I did a"double bypass," I guess, this past winter. I replaced the cam chain and tensioners and the mechanical seal. After getting it started up and...

    I have reviewed other threads, relative to internal coolant leaks, but I'm still not certain as to the likely specific source of the problem. I have a 1980 CX500 Custom, bought through a dealer (likely with (1) owner) in early summer 2015, with 9,000 miles, having been apparently well...

I have stripped down the waterpump and found 2 potential causes. 1 The rubber gasket is very compressed but as the leak was coming from the vicinity of the weep hole I decided to check the mechanical seal. This...
