You doin't have to buy a gasket set .... I've had that clutch cover off better than 10 time and never had a leak.
Get some "ultra gray" form a gasket from the parts store and aply a thin coat to both side (carefull around the top where the oil passage is) then let it dry for about 10 minutes and finger tight only put the bolts in. After it sets over-night tork the bolts on the soft side.
be sure to rub the sealer as you put it on ,,, you will be able to see and feel the good contact , remember just a thin layer on both sides.
Be sure to get the specal washers in the right place , (I use a little grey on the bolt heads where the washers go.)
Wish you could have made the Dragon trip again this year. I've thought a lot about that "top-heavy" load you had , I would'nt have wanted to ride with a load like that ,,, doin't know how you did it.
