I'm looking to do more of my motorcycle maintenance myself, and am wondering what I should be investing in, when it comes to tools/devices. What are the basic tools that I'd need when starting to do more of my own maintenance on my motorcycle?
If you buy a 3rd party maintenance manual for your bike (Clymer, Haynes) it will include a list of tools. They usually have a general list and a specific list.
Don't go out and buy them all at once. Before you begin a new procedure, read through it carefully. Clean your workspace and gather the tools you will need. Plan a shopping trip for what you're missing. Be prepared for a second (and third!) trip when you realize something else you need. Having a way to get to the tool store without your motorcycle is a must. (I had a second motorcycle. But it was often in pieces, so then there was the third bike...)
There are two questions only you can answer for yourself:
For example, you can do a lot with an adjustable crescent wrench, but a good set of combination wrenches will be easier to work with and is gentler on the machine.
Snap-on vs Harbor Freight?
Working with a good quality tool is a joy, and having the right tool for the job makes things go more smoothly. But a large toolset is also a burden, as you have to organize, sort through, and maintain all those tools.
A 3rd related question is about your threshold for doing work yourself vs. taking it to a pro. Start with something simple, like an oil and filter change.
