G'day men. Have just fit a 50 tooth rear sprocket to my 08 TE450 (replaced standard 47) and now cannot refit rear wheel as chain is too tight. Can anyone tell me how many links will I have to buy to get the standard chain to fit - CZ 520 ORM? Hopefully do not need to get a whole new chain as original only has 700 KM's on it and is in good nick. Thanks for any help.
