This very night. Wife asleep. Sky dark. Traffic nil. Time to ride. Backed the GT out of the garage. Went back in to grab togs. Oil pool the size of a dessert plate. Went back outside to roll GT back in. Grabbed MagLite, paper towel, glasses. Swept floor, laid down on same. Wiped down underside of engine and inspected towel for oil. Found drops hanging from filter screen bolts. Cleaned up oil, tightened bolts. Blew off ride.
I have about 500mi. on it now, took it in for the first oil change at 328mi. In the interim I have averaged 35mph with a few slow revving runs up to and maintaining 55mph for short distances. Each time I've parked it there's been no oil on the ground(rode a 69 Triumph, you kind of look for that), and nothing on the rear worth noticing. The only reason I found this leak is the GT has set for 5 days since my last midnight skulk. A slllooow leak here, folks.
Us fresh RE owners might check our drain plugs 'n' such after each oil change; ride for a while, and re-torque after the bike is cold. Just like doing a re-torque on a reassembled motor. I recall on the old forum a thread on drilling the bolts/plugs for safety wire, a damn good idea.
