The GPZ900R had a long production run, didn’t it? (84\u201303, up to A16)
When you think about it that way, the ZRX also had a long production life (97\u201316, up to the Daeg).

The base is similar too… Products with long breath build loyal users and deep affection!

There’s something nice about things with lots of compatibility.

This is a clean GPZ900R job. It’s reassuring and much appreciated. <\/p>\n\n\n\n\n\n\n\n

I’ll check the tire manufacturing date.

Sometimes even with tread, you know. It’s something to reconsider during maintenance. <\/p>\n\n\n\n

On the other hand, each part is a cauldron of tension, so to speak.

I’ll check the tire and wheel runout.

For example, if the handling feels off? Air pressure is important, but sometimes the tire bead isn’t seated properly and you get a wobble.

One by one, check one-two. <\/p>\n\n\n\n

There’s no manual, so we proceed by understanding the current state.

The spark plugs are clean, so we’ll reuse them.
Only the #4 plug cap was rusty and loose, so I’ll replace that. <\/p>\n\n\n\n
