Eh? What kind of shops? Do they know you're working on a 200cc bike? Did you leave the chain in the motor? As long as the chain is still on the sprocket inside the motor, you should be able to join the new chain to the old one with a piece of wire or something & very carefully pull it through. (Twist the wire so that the spacing between the new chain & the old chain is the same as the link-to-link spacing.)
Z1 Enterprises lists a master link for a 219H chain. Might be worth calling them to see if they can get you a 219T link.
If the chain is off the sprocket inside the motor, it's a different story. If that's the case, you will need to split the cases.
