I have a 1986 Venture that I purchased last fall. About two weeks after purchasing the bike I pulled a boneheaded mistake by driving off of what I thought was about a 5" curb (that turned out to be more like 8" tall) at a very slow rate of speed and basically dropped the lower crankcase ontop of the concrete curb. I noticed a pretty significant oil leak under the bike when I got home. At first I thought I had cracked the oil filter cover but after hauling it to the local Yamaha dealer to have it checked out it turns out that the crankcase itself was "bent". They gave me two options...turn it in to insurance as totaled (I don't have full coverage) or "JB weld" the oil cover on semi permanently until the next oil change at 10 or 12,000 miles. The "JB weld" idea worked pretty good last fall with just a few minor drips but this spring it seems to be getting much worse. Any suggestions on what else I can try?
