Wrench it:
- Get comfortable with taking the seat and tank off. This allows you to see how the machine is put together.
- Start with simple things, like brakes, tires, spark plug, oil/air filter and oil change.
- Don't worry about breaking things yet. Once you become more familiar with how the machine is put together, and knowing how to navigate this site, you'll be in a good position to know how not to break things, and, how to fix them if you do. The most frustrating problem is snapping a bolt off. It can be fixed, with patience and finesse.
- Not wrenching this motorcycle will probably lead to more problems that wrenching it. If your turning the bolts on this thing, it's probably going to be done right...eventually
- You'll probably never have to take the engine out, or apart. You may have to take the carb out once.
- Most motorcycle wrenching is to inspect and adjust things. Have a camera ready so you can ask "Is this thing 'sposed to be bent like this?"
- You will get oil leaks. They can be fixed. And, unless it's gushing oil, that work can be scheduled for the off season.
So yes, wrench it. Take your time. You can accumulate the tools you need over time. The cost of the tools is usually cheaper than shop labor, and, you don't have to figure out how to get the bike to the shop and back.
