All this stuff is easier without the Top airbox part, but the big air tube coming from the front is "welded to the plastic", if i apply force, i'll breack it, for sure.....any tip on removal?
i guess it's impossible the change the fuel regulator hose without removing the airbox right?
This part of the design, doesn't brings an easy going manipulation....
Any tip?

I've the tank removed, the 90 degrees pipe, doesn't want to be free.
I need to apply force and i'm affraid to breack it....anyway, i can buy a replacement and continue with the fuel hoses as you describe...
txs!

When you put the air filter back in if you put some Armor All in the groves around the perimeter on the top and bottom of it then it will slide in more easily.
Proper air filter installation:

You've already got the air filter off but for future reference the easiest way to get the air filter out is to apply some leverage to lift up
the rear of it.

i used the little shovel with patiente and i fill half oil filter case with dirt. A lot
Then i use a vacuum, and paper towels, and little brush to arrive to something "close "to ok, along with a degreaser.
Tomorrow new fuel lines, and vacuum one, along with a stronger degreaser , withgout touching any rubber.
The Pressure regulator has a bit of old ( 6 years) fuel, wtf, how it smells, ugly!

If you insert a spring inside the line, yo can even go far more than 90 degrees maintaining the diameter.
I went to “la casa del resorte” ( house of spring).
They didn’t have the exact one to fit into the 13x8 fuel line, and the guy propose to me to build one in stainless steel. He build an exact one in 30 min.
I like this things.

Looking for a solution to make a 90 degrees in a fuel line ( the one that goes from the regulator to the fuel tank), I read the spring tip.Usually the spring is placed on the outside so flow rate and pressure aren't affected like these (https://www.google.com/search?client=safari&rls=en&q=unicoil+hose+bender&ie=UTF-8&oe=UTF-8). I'd be wary of your method.
Post by: foliver on January 26, 2022, 12:11:38 PM
I've seen a vid that use this method for injectors, so i thought that for return, is less problematic...

But you are right anyway.
As my line is not original, so not bended, i find this solution a compromise.
Thanks for your opinion!
Now, i'm fighting with the big water hose, the one that passes into the engine......

I'm sure I will be corrected with many horror stories, but in 30+ yrs ridin', wrenchin', readin' about these bikes, and having owned a "few", I am having difficulty recalling ANY coolant hose failures. Purdy sure those on the '85 Big Red are original.
I have one. I did a 50K complete service on my 94 K1100RS at my dad's place in SoCal. Instead of using the drain plug to drain the coolant I disconnected the big hose that goes into the water pump. A few hundred miles later after filling up in Carmel on my way home up the coast I noticed a big puddle of coolant under the bike. There was a hole in the coolant hose down near where it enters the water pump. Being a BMW part, it had conveniently decided to fail on a Monday - when the dealers are closed. It's a long sordid tale involving a ghetto repair in a vacant Santa Cruz parking lot but I did manage to "limp" the bike to a friend's place in Sacramento without overheating the motor. He lived near A&S who luckily had the hose in stock when they opened on Tuesday morning. Ever since then I always carry a roll of Rescue Tape when I ride. And I also drain from the bottom of water pump, not the hose.
But that one instance is the only coolant hose failure I've ever had owning many K bikes over hundreds of thousands of miles so I agree with your assessment that K coolant hoses are, for the most part, highly resistant to failure.

Hi Laitch, i'm with you on that, nice solution if you have a little space arround, but i was thinking that the diameter of the spring ( the interior) is the same that the ouptut plug on pressure regulator, so, my thinking was, is as the pressure regulator was 5 cm longer...so i accepted this method...
I've seen a vid that use this method for injectors, so i thought that for return, is less problematic...

Regarding the radiator hose, warm it up with the hair dryer, fold it lengthwise and slip it through the hole in the crankcase cover.
Post by: foliver on January 26, 2022, 02:27:49 PM
thanks for the tip , i'll try.
I remember last time, with the same hose in 2009, i was perspiring like an attached pig.

I was the victim of a vehicular assault that totaled my K100RS that had 128,000 miles as well as the KIA sedan that attacked me.Your relatively intact survival from the encounter was astonishing. A photo of that wreckage should be posted here under the title, The Case Against Slowing Down. :laughing4-giggles:
Post by: foliver on January 26, 2022, 02:50:17 PM
Great, great idea. I even bring soap to apply and it was not necessary.
Thanks!
I am even able to go to a ball without taking a shower. Dry.

I hope not!

I was able, somehow, to walk(actually limp) away. Lots of sprains but no broken bones. Still have stiff neck and sore shoulder after 3 years.
despite everything, a lucky man.
So, the hoses and you survived.

And I also drain from the bottom of water pump, not the hose.
What a surprise, it's a pain in the ass to loose water, and for that cause, 1 in 3.000.000
The hoses that were my the bike when i bought it in 2009, were ok, but one has a little crack, and i change all of it.
Waiting for the original parts, i've found here, the same hoses, with the sames shapes....amazing.
So i used the ones i bought here, until today, that they were ok, but i'm dismantling all the stuff, so i decided to install the original ones.
I guess if i don't have an accident, they will last for ever ( for ever me, ja! )
