GPZ1100 (Air-Cooled) Whether it has an F or not.
It’s complicated…
Well then The tires are rock hard <\/strong>and the forks are completely soggy <\/strong>in condition.

Since the carb is now sharp <\/strong>we have a refresh request for the moving parts (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n\n\n\n\n

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

So let’s get to work.
Since it’s a custom bike that’s been in long-term storage, I’ll check each part as we go. <\/p>\n\n\n\n

Looking up for a moment… they’re rebuilding the stem shaft (non-hollow).
We don’t usually use a front racing stand, but lifting the front for long-term storage can be problematic. <\/strong>*Like painting and such… <\/p>\n\n\n\n

Michelin POWER6 (New) <\/span><\/strong><\/p>\n\n\n\n

Basically, I’m a Michelin fan.
They’re light, soft, and have good durability, so when people ask for a recommendation I push Michelin. <\/strong><\/p>\n\n\n\n

We’ll assemble it with the recently popular Gale Speed 11.5\u03c6 air valve. <\/span><\/strong><\/p>\n\n\n\n

Make a pipe with a diameter that fits snugly onto the air valve and secure it firmly. <\/p>\n\n\n\n

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

Hmm… I’ll put it back (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

Each part is looking a bit tired.
When you polish things carefully during work like this, they should come out looking sharp.
The usual no-touch glossy finish ~ (*\u00b4\u03c9\uff40*) <\/a><\/strong><\/p>\n\n\n\n

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

The inside of the wheel is spray wax FW-1 <\/a><\/strong>to give it a nice glossy finish. <\/p>\n\n\n\n

That’s how I polished it.
<\/p>\n\n\n\n

I also polished the end section after removing the adjuster. <\/p>\n\n\n\n

I also oiled the speedometer cable. The torque rod bolts are a bit worn, so I’ll replace them. <\/p>\n\n\n\n

POWER6 has a gentle round shape with high expectations (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

120 horsepower on an air-cooled bike from this era is amazing (*\u00b4\u03c9\uff40*) <\/h2>\n\n\n\t\t
