The first thing that I would recommend any new rider who wants to start working on his/her own bike is a
Service Manual. Having one readily available to you at all times, will save you a lot of time and money.
Other things you will need;
A good set of tools (to many others to list, some will be determined by the level of maintenance you will be doing but, a
torque wrench and impact wrench is highly recommended)
Front and rear stands or other type of lift
Small Air compressor
Two
vacuum gauges
Brake Bleeder
Tie down straps
Small parts (start amassing stuff like cotter pins, plastic rivets, well nuts, screws, bolts, light bulbs replacement cables & hoses)
