The shaft from Bito is excellent.
Electroless nickel really is the best… I’m genuinely impressed.<\/p>\n\n\n\n

It’s so refined and delightful.
It’s for the GSF1200, but I’m thrilled that they have such niche models in their lineup~<\/p>\n\n\n\n

When the shaft and bolts are beautiful, it feels right (*\u00b4\u03c9\uff40*)<\/h2>\n\n\n\n

Conversely, when they’re shabby, it looks pathetic.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It must be machined to M20*P1.5. Please be aware.<\/h2>\n\n\n\n

Now let’s assemble the fork smoothly.
I love non-cartridge forks… the ultimate in simplicity (*\u00b4\u03c9\uff40*)<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Inner tubes are perfectly straight. Good condition (*\u00b4\u03c9\uff40*)<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Cylinder bolts (just plain M8) replaced every time. The smoothness of the threads needs to be checked.<\/h2>\n\n\n\n

We vacuum out the last tiny bubbles.<\/h2>\n\n\n\n

*I don’t think it makes a big difference. It’s the thought that counts.<\/p>\n\n\n\n

The Inazuma 1200 STD is 0.7 kg\/mm.<\/p>\n\n\n\n
