How much should this motorcycle repair cost?

It's an easy job to do. You should have had a go at fixing it yourself really. If you can maintain your own bike then it will be a lot cheaper. Garages cost a fortune in labour and most work by hourly rates. Thus an hour and ten minutes will probably be charged as two hours! Nobody here can give you an accurate estimate, because every garage varies, depending on where you go. Hope it's not too expensive for you though!  more
