I found a very cheap 2004 Volusia and while I don't need another bike (or project), I am very tempted. The owner states that the issue is in the transmission: "There is a problem with the transmission. Bike starts, you'll hear a lot of clanking when the bike is turned on." I found a 2002 Volusia transmission for sale for the price of a Chipotle meal for two. How difficult would it be to swap it? Would I need to pull the engine or can it be done in place?
