Well, here we go with the continuation.
Turns out we didn’t finish it after all★

Finally got what they wanted to install.
YRP Easy Clutch Kit

Now that’s brilliant thinking

I’m a bit worried whether it’ll stretch that much and cut cleanly
Replaced the stock clutch wire with a new one and it’s gotten a lot better
Once we install this next, it’ll feel light, or more like a soft, squishy feel
Test ride and report back later

630→530 conversion along with
“DID ZVM-X & Sunstar Service Kit (+)” oil-cooled

Since it’s 630→530, the outer diameter changes so the tooth count will differ.
Plus they asked for the front to be about 2 teeth shorter in ratio★
In cases like this, it’s better to set it so the final drive can swing both ways
Maybe a bit shorter after all! Or maybe a bit longer
The chain length balance comes into play too, you know

Oops
