It’s suddenly complete (*\u00b4\u03c9\uff40*)<\/h2>\n\n\n\n

My heart is set on the Zephyr 550 though…
Let me jot down the details briefly. <\/p>\n\n\n\n

The engine is an overhaul-completed engine from Bright Logic from quite some time ago.
In other words, it’s a used engine, but we’ve disassembled it.

We’ve done gun coating and lightening work.
The displacement is unclear, but it’s probably 850cc?

The spark plug has been replaced with BR8ES. <\/p>\n\n\n\n

<\/div>\n\n\n\n

<\/p>\n\n\n\n

The carb is a Mikuni BST36\u03c6 from a GSF1200.
Since I was planning to ride it myself, it’s been cleaned up beautifully with wet blasting. <\/p>\n\n\n\n

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

The forks are standard 35\u03c6
Overhauled with wet blasted bottom cases
Checker Flag KYB for that authentic look.

The calipers are also overhauled, and the caliper bolts are Yamaha OEM. <\/p>\n\n\n\n

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

The turn signals are repro GS-type units.
They’re a bit smaller and it’s a classic swap mod from back in the day. <\/p>\n\n\n\n

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

The lens is a multi-reflector (Raybric)
Not some sketchy Chinese knockoff. <\/p>\n\n\n\n

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

Unfortunately, the meter is a GS550 unit.
Since it’s from a different year, the gear position won’t light up. <\/p>\n\n\n\n

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

It’s in miles, so please write it in by hand or apply a Z conversion sticker.

The tachometer is a bit temperamental ( \uff1b\u2200\uff1b) <\/p>\n\n\n\n

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

A quality master cylinder that someone had thrown away has been given a second life.
It has a lever adjuster <\/p>\n\n\n\n

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

The bodywork is relatively high quality (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

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

I’ve bought line stickers for the bodywork, so feel free to use them if you’d like. <\/p>\n\n\n\n

The rear master and rear caliper are also overhauled. <\/p>\n\n\n\n

The rear has new pads and pins.
It also features a nostalgic Yoshimura Speed Flow. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Advantage aluminum swingarm. <\/p>\n\n\n\n

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

The rear suspension I bought at Kari-Ten is brand new (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

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

The battery is a brand new Pro Select Battery GEL.

The harness has been rewired with a repro harness. <\/p>\n\n\n\n

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

The regulator has been upgraded to a modern heat-reducing voltage control unit
The turn signal relay has been swapped to the usual Daytona unit

The tube fuses have been changed to mini blade fuses. <\/p>\n\n\n\n

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

It’s subtle, but most of the itchy spots have been taken care of,
so you should be able to enjoy it with confidence. <\/p>\n","protected":false},"excerpt":{"rendered":"
