After some twists and turns, it’s finally complete.
We started from a Z1R that looked good on the surface but was basically a restoration base.

I spent quite a bit of time on the final touches with the original VM carburetor, air cleaner, and original muffler, but now it’s finally become a spec I can enjoy riding anywhere (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

So that’s the final episode.
After riding 200 kilometers, it’s become an excellent bike. <\/p>\n\n\n\n

The drain bolt wouldn’t come out by hand and wouldn’t go back in.
Forcing it wouldn’t be good, so I’ll tap it just in case. It’s M20-P1.5. <\/p>\n\n\n\n

After investigating, the bulb socket on the headlight side was deformed, so the bulb wasn’t going in all the way
and was tilted.

This kind of thing happens, so it’s best to check with a headlight tester when replacing bulbs. <\/p>\n\n\n\n

This is a plan that minimizes modification, has high versatility, and keeps costs down. <\/p>\n\n\n\n

I’ll use a fairly large tie base.
The wider the surface, the better.
Lightly sand the adhesive surface with Scotch tape or similar, then degrease thoroughly for reliability.

VR2 is the one with aluminum tape applied.
Use aluminum tape to gain surface area and fix the tie base to the tape.
This way, when you want to remove it, you won’t get frustrated peeling off both sides.
For VR2, I use 3M double-sided tape like what’s used on ETCs.

Fix it securely, and if you want to remove it, do it smartly.
