Cost alot unless you were doing the labour.
$4k is alot to spend on a bike that requires a break-down to get it back to 100%
1/2 that amount would be reasonable. Spending more isn't increasing its value !
Link below will give you individual component cost for gearbox bits as a guide.
Item #5 and #14 appear to make up 2nd gear. Cogs need to be replaced in pairs else they wont last.
You wont know what parts you'll be up for till you have the thing apart
