i hate you for your warm winters in florida. i live in pa and its going to be in the low
40s and raining for the next few days!
a slow leak like yours i wouldn't worry about. its easy to just keep an eye on the oil level, but if dmike can get a pic of that gasket and its easy to get to, it could be a worthwhile fix.
on a side note to one of the earlier posts, the side rails do support the fender. they provide a connection between the front part with actual structural supports to the back where the passenger rest is (on older ones anyway). take that rest off and you can watch the fender flex between the rails. you should be alright without them as long as the passenger weighs less that, saaaay, 250lb? and dont try to land any jumps with her on there either
