Why This Matters
The reason I started doing my own work isn't because I enjoy dismantling bikes — it's because a workshop once quoted me several hundred dollars for a relay and some wire. I bought the parts for under fifteen dollars and spent a Saturday afternoon figuring it out. That session set the direction for everything that followed.
None of what I do is complicated. The MT-03 is a straightforward naked — no fairings to battle, no labyrinthine wire harnesses. What I needed was a solid set of tools and the confidence to use them. This is that list.
Home Session Kit
These are the tools that come out whenever I'm working in the garage. Every item earns its place. The comfort items at the bottom aren't a joke — a good session is a slow session, and slow sessions don't produce mistakes.
On-Bike Tool Bag — Always Carried
This is the separate kit that rides with me at all times, packed into a small pouch under the seat or in a tail bag. It's not a full workshop — it's a get-home kit. Everything chosen to handle the most common failures at the roadside without calling for a tow.
Where to Source
// Shopping Links
[ON JIS SCREWS] Most Japanese motorcycle fasteners are JIS — Japanese Industrial Standard — not Phillips. A Phillips driver seats but doesn't engage the recess as cleanly. Over time, using Phillips on JIS rounds the head. A JIS #2 is the size you'll reach for most often on a Yamaha. Worth having one in the kit.
[ON BUTT TERMINALS] The adhesive-lined heat shrink butt connector does two things a plain shrink tube can't: it mechanically crimps the wires and seals the join with adhesive when heated. A twist-splice covered with plain heat shrink is not a proper electrical connection — it's a contact point held together by optimism. Vibration loosens it. A crimped terminal won't move.
[ON THE COMFORT SETUP] The chair and the speaker are not optional extras. A standing session gets rushed. A rushed session produces mistakes — wrong order, missed connections, bolts done by feel. Sit down, put something on to listen to, take your time. The bike does not go anywhere faster if you're stressed about it.
[ON CARRYING TOOLS] People underestimate how often small issues happen far from help. A nail in the tyre on an empty stretch of road between Johor Bahru and Mersing changes your whole day. A plug kit and a small pump — or even just the plugs and a petrol station 5km ahead — is the difference between a delay and a tow. I carry the kit every single ride now.
