I'm taking off everything on my 1986 yamaha venture royale star. New to bikes and builds. Wanting to make it a bare bike. Just the basics. What I'm looking at in this very moment is taking the air shocks out of it. Rear shock is easy but front is in the forks and I'm at a loss at to what I can or need to do. Is there a replacement fork that doesn't have air? A way to rebuild them without air? Any info would be appreciated. Whether just advice or links. Thank you in advance.
