Yeah...they all seem to leak out of the cover gasket like that. All you can do is make sure your bolts are tight and wait until it gets too leaky. Then it's the famous head gasket job!

Viggy, I've got that slow head cover leak as well, it just looks terrible. But with an old bike (mine is an '84) you take your chances when disassembling for something like that. For my money, I'll just top up the oil. Probably only loses $1 worth per season. Christoph On Tue, Apr 21, 2009 at 9:16 PM, Mr Viggy <[email protected]> wrote: Two cylinders? As in 2 total? :) I don't know about Hawks and oil, but I do have a slight head gasket leak. It kinda sucks, because there's not enough oil to change it, but just enough to annoy me!!!
