85 XT600N Oil Tank Leak
I've recently returned this bike to service after a long restoration. It is now my street bike and I'm loving it. But one irritating problem persists. The oil tank leaks from the drain hole. I tried replacing the drain plug and copper washer with new OEM, but to no effect. It doesn't leak until the tank comes up to temperature, at which point it spouts a regular drip that slowly drenches my swingarm and chain guard in hot oil. I tried wrapping the plug in silicone tape, but still the leak persists. As far as I can tell the tank is sound and not cracked. Any suggestions? Has anyone else encountered this problem? I am considering having the drain hole sealed by a welder, on the assumption that I would still be able to drain out all the oil from the crankcase.
Thanks for any comments or suggestions.
