One shop quoted me $1000- to remove my existing motor-gearbox, and fit another motor-gearbox. They charge a fair bit per hour but I think this is massively expensive. Their argument is that some of the bolts might be binded (it's a 93' GSX-R 750), and they might run into other issues. I still think it's too much. How long should it take a fully equiped bike shop at most? All I'm paying them for is the labour. Thanks.
