The AVL forks are the same as the G-5. As I look at the manual, it looks like a real PITA! There are some special tools called for, but not having done it myself, I'm not sure what is really required and if the job can be done without them!
Their manual is rather confusing. It looks like the lowers can be pulled and leave the rest of the forks intact. If that's true, the job won't be bad, and you don't need any special tools. If you have to take the rest of the forks out of the triple tree then it's a pain, but looking at the drawings, that doesn't appear to be true. It looks like that once you drain the oil and take that big cap off the bottom, the lowers should just slide off complete with the seals.
Not quite as easy as good old Tri/BSAs, or is it?
When mine start leaking, I'll give them a shot!
