What is your budget.
To have a shop do it all the way with parts will run over $10,000.00.
What are you thinking of, a full tear down and rebuild, or just make it work?
There is $2000 to $4000 in just consumable parts (gaskets, seals, bearings, shocks, chains, bushings, tires, pistons, valves, guides, fluids, coils, rubber parts)
plus parts found to be worn or damaged.
Not to mention parts to replace or recondition, usually replace fork tubes, seat cover.
Plus there is Paint, at least $1000 for tank and sidecovers.
then there are the upgrades, new carbs $400, ignition $200, head steady $200
Then there are the niceties, Corbin seat $400, Laansdowne dampeners $350,
How far down the rabbit hole do you want to go?
