My question is for the folks who've got the R6 forks on their bikes. How difficult is it to change out the oil -- are there any special tools required for pulling the forks apart? That's really my question. I've got a copy of the R6 manual and they show a couple of special tools in use but I'm wondering if they're absolutely necessary. I just don't want to start unscrewing the top caps and have something come shooting out...
