For the price mechanic asks for his work you can buy all necessary tools and do the work by yourself, then you can use those tools in the future multiple times with no need of mechanic help. You also can do the work faster if you already have all necessary tools than if you let the mechanic to maintain your motorcycle, because of a good mechanic likely already has a bunch of customers he should work with before he can start working on your motorcycle. You also probably will spend even more effort to find mechanic who can fix Buell, figuring out how you can transition your motorcycle to him and how to get it back, you will probably learn the same and will be able to do the work by yourself after you will have spent your time and effort on mechanic.
