[QUOTE="Gary Gittleson, post: 95991, member: 3625"] It's time for me to post an update. I just took a ride of about 90 miles and the bike shows no signs of oil leaks! Kicking my heels! So I thought I'd post the modifications. 1) I made a "carb slide" gadget similar to David's out of copper pipe by cutting a one-inch piece lengthwise in half, working the shape to fit around the return block in the oil tank and soldering a flat piece to one end. I then drilled a hole for a screw to fasten the device to the block at the metering screw hole. I used a short screw from an old Monobloc carb to hold it down. 2) I obtained a non-breathing oil cap from Coventry Spares 3) I drilled and tapped an old valve inspection cap to take 1/8" US pipe thread (npt), cut a short length of threaded brass pipe, opened the cut end with a drill bit and soldered a piece of brass tubing into that. I installed the modified cap and pipe over the rear exhaust valve. With that in place, I ran a piece of 5/16 rubber hose connecting the chain oiler outlet to the valve cap. 4) My bike is a D, so I already had the valve-cap breather setup. I have it over the intake valve on the front cylinder. I think it's supposed to be over the exhaust valve but I wanted it to be as high as possible. 5) The breather cap is connected to a one-way valve which in turn is connected to a long rubber hose which exits behind the rear axle. So far, as I mentioned, everything is dry. Even the breather-hose exit is dry. So is the valve lifter cable area. [/QUOTE]
