The GPZ900R sure was everywhere back then!

I have the impression that Kawasaki bikes had really loud exhaust notes. Maybe in today’s world you can’t even warm them up properly?

Wasn’t there a vibe back then where it was kind of okay on main roads?
Everything was pretty laid-back and had a certain charm to it.

Let’s start by taking off the cooling system parts. <\/p>\n\n\n\n\n\n\n\n

The owner said they don’t need the oil cooler, so we’ll remove it. <\/p>\n\n\n\n

Such a great item is available for purchase.
Oil cooler-less bypass pipe kit (for GPZ900R) <\/a><\/p>\n\n\n\n

Since it’s a pipe, it’s perfect for those with tight muffler layouts! You don’t have to worry about aluminum fitting deterioration, so it looks really good. <\/p>\n\n\n\n

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

The drain is also avoided, making it super simple!
The part quality is good too,
and I find myself thinking what a great era this is. <\/p>\n\n\n\n

A bit too much came out and some gravel got in, so we’ll make a call on whether to top it off or replace it. <\/p>\n\n\n\n

We’ll take this tube off too and clean it up while we’re at it.
We’re a bit short on parts, so we’re ordering more. <\/p>\n\n\n\n

I’ve gotten pretty good at removing the upper cowl lately. <\/p>\n\n\n\n

That’s all for today! <\/p>\n","protected":false},"excerpt":{"rendered":"
