Old bike woes and workarounds, radiator hoses

"That part is obsolete. Good luck finding it."
If you have an older bike, then you have surely heard this from parts houses. So what does one do?

Adapt and persevere.

My 1987 Yamaha FZR1000 is now 33 years old and the original radiator hoses were showing their age. I needed new ones. Here's how I did it:

The hardest part of this step is finding a parts house worker or manager that can either allow a customer to do one's own search or be willing to do it for them; take your hoses and search for matching or near-matching bends, and matching hose diameters, to the original. I went to a local Auto Zone, during a slow period, and got the help that I needed.

Two hoses were found, that matched bends of the original hoses surprisingly well, Dayco E71986 ($23.99) and Dayco E72081 ($9.95). carefully measure and cut the hoses longer than you think; it's easy to trim it shorter and impossible to lengthen it later.

The radiator cap was original and the rubber gaskets were cracking. From the selection at the store, I located a perfect-fitting cap with the proper pressure rating of 0.9 atmospheres (~13psi); Duralast 7513 ($8.99).

The end result; good as new!

Sure, the water pump seal may be the next thing requiring attention, but that's old bikes for you.

Nice work! Sometimes research like that is fun... that is if you dont have to have those wheels to get to work the next day. ;-)

Cool project Dave.

Adaptation and Perseverance, is always preferable to endeavoring to persevere. With the former, you keep a cool bike running cool. With the latter... Well let's just say your poor FZR might of ended up in Kansas pulling a Radio Flyer for the Union.

And, they don't have any curvy roads worth a damn.

"What's the part number???" is another one...so many clerks are plain helpless without one. A very few have their eyes light up and ask about what I'm working on (customized mc parts) and are more than happy to help, I love those guys.

Did mine about 10 years ago only I used the local NAPA parts store. I agree with the parts counter guy needs to want to help. Let's keep our FZR's running forever. (I bought mine new!)

Dayhum! An old bike that has a radiator. I'm so old I that it was almost 10 years after I started riding that there was such a thing as new bike that was anything other than air cooled.

I am the second owner of this one. The original owner crashed it in 1989. He seldom rode it, as it was no longer pretty, and decided to sell it in 2014 (it had been sitting since 1992. I rebuilt all of the brake and hydraulic clutch assemblies, rebuilt the carburetors, adjusted the valves, mounted a handle bar on it. . . It's living life as a street fighter these days. I still debate on whether to turn it into a tasteful bobber, but all the existing, original components are still unaltered, stock. It now has almost 30,000 miles more on it than it did when I bought it.

We should talk sometime. Mine has undergone some "upgrading". I have a few extra stock components laying around like a set of forks complete with racetech gold valves and springs for 170 lb rider.
