If it's not leaking coolant, or oil, and it's not overheating the best you can do is leave it alone. Takeing the pump cover off won't do much for you. All you will see is the pump impeller. Then you will have to clean it all up, get a new gasket to put it back together.

I bought my GT550L new in 1974! I think I only put about 8,000 miles on her last year. 3,000 of those in one week, riding down to Deals Gap and back!! Going to do the trip again this August and put a few more miles on her for her 40th. anniversary!!
Is it oil or coolant leaking out of the weep hole? My GT750A had a coolant leak last year. Turned out to be one of the o rings had a twist in it! A lot of work and aggravation for a simple installation brain fart!!
Ya I no what you mean. Mine was an oil leak from the top seal in the pump. Then fixed oil leak from neutral switch, and then fix oil leak coming from clutch adj cover. Planning on putting some miles on it this summer. Good luck on your trip.

Well after a new water pump, snugging up neutral switch bolts, installed new oil seal in clutch adj cover I think we got it. Took it out for a little spin today, (about 20 miles) parked it on cement floor in garage. Five hours later, guess what, NO OIL LEAKS. Not a drop. Long time coming, but well worth waiting for. Thanks again to everyone who gave me there expertise.
