GPZ900R Coolant Leak Repair

Without removing the carbs! Thoughtful design that allows maintenance… or so I think (*´ω`*)

Like everything else,“it’s a pain to remove when it’s seized up”
I’m not sure what comes next,but I want to work with “the future in mind.”

Drained the coolant. Bikes with drain plugs are the best, right? ♪

Bikes without them do exist, so I find myself thinking… wow.

Once removed,it was in “oh wow” condition.

Even with this, it doesn’t leak… I was genuinely impressed as a cautionary tale (*´ω`*)

I’ll replace the thermostat too since it’s probably going anyway.
Man, it’s dirty…

It’s probably not an O-ring… some other material?
Liquid… whoosh…

It doesn’t leak! (Amazing!)

I’ll gently finish each part and assemble them.
By the way, even if I clean it up, the performance won’t… really improve. Probably.

It just feels better when it’s clean. That’s the only reason I do this work.

I’ll also replace the parts around the carb heater.

The hose clamp is a masterpiece: “Norma”

It’s better to avoid ones with grooves as much as possible.
With lots of grooves,“excess material”gets into the intake manifold, and you sometimes see people like that…

Oh!“For irrigation”they’ll say! So be careful.

With Norma, it’s harder to damage the other side, and it prevents groove breakage and torque loss from deformation.

After that, a test ride and invoice, and we’re done.

(*´ω`*)Here’s this time’s hose clamp.
