The Rusty Brick - '92 K100RS

[MaraudeRS]

Another big kudos to Laitch for recommending I pull the fuel pump and check the sump...it was full of crap.

While I had the pump out I cleaned it up real pretty and cleaned out the screen. It had a bunch of gunk built up around it so I scraped it clean.
l
I also replaced the fuel filter. I blew thru it and it felt a lot more restricted than the new one that came with the bike. The PO must have intended to replace it and never got around to it.

Stupid question alert! Can I run the motor without the fuel cap completely sealed? I'm still waiting for the seal to arrive but I'd like to run the engine asap so I can order anything that I'll be needing.

You can run it but I wouldn't ride it unless you want your nether regions soaked in fuel. :hehehe

:hehehe Ok thanks. Hopefully I'll have some time to get the spark plugs replaced tomorrow then I'll fire it up :clap:

Throw half of a bottle of Techron fuel system cleaner in the tank with a couple gallons of no ethanol gas if you can get it.  If there are a lot of miles on it you might want to dump a bottle of SeaFoam in the crankcase to clean the sprag.  Then fire it up and let it run about 5 minutes until it's hot and shut it down to cool off.   Do this a couple times a day while you are working on it and you will go a long way toward cleaning out the crap that may have built up in the injectors and fuel pressure regulator. 

Once the bike is on the road, run it about 20-30 miles and change out the oil with the SeaFoam in it and replace with good synthetic and a new filter.  I like to use Shell Rotella T6 full synthetic SAE 5W-40 that I get at Walmart for $21 a gallon.  I use a Carquest filter #85348 that is less than $5.  Another good filter is the AC PF-53.

I had a friend in the Peace Corp who served in the neither regions. She said it was almost impossible to find good fuel but it was still enjoyable down there.

Depending on how much time you've got....


I pulled the tank off my stinking K1100, white vinegar (6Litres) for 2-3 days and wiped / scraped it out. Then I got the hose to it and flushed grit and crap out through the fuel sender (sensor) hole. Then in the sun to dry out. Then I vacuumed it. Clean result.

Your fuel pump and screen look reusable. Had to bodge my screen (some fine brass mesh laying around and some tie wire twisted tight). Fuel filter off Holden Commodore (utilitarian Australian equivalent of a chevy). Just want to check if the bike will run... when I get round to it.


Like i said before: internals on our bike seem good, externals well salted.

The bike has 41k miles on it. Do you think I need the SeaFoam? I already put the new oil filter in and Mobil 1 oil so can I do the SeaFoam at the next oil change?

Yes, I did the vinegar treatment for a few days and the inside of the tank looks great. Got the spark plugs replaced yesterday
but I forgot to pick up some gas on my way home so I'll hopefully be able to do it this morning before our Thanksgiving festivities begin.

Happy Thanksgiving, fellow Americans!

Don't do the SeaFoam in the crankcase now that you have the good oil in there.  I wouldn't leave it in there for more than an hour or so of engine running time before doing an oil change.  Wait until a day or so before the next oil change. 

I would still do the Techron in the gas.  You don't know how much varnish has collected in the fuel system and you want to get it out of there.  The auto parts places around me have it on sale now, buy-one-get-one-free.

Sounds good, thx. Funny story, I bought a bottle of the Techron at Autozone when you first told me about it and I think it was around $10, then I go to Costco about a week ago and they had a case of 6 for around $20! Needless to say, I now have lots of it.

Careful, K bikes have special needs when it comes to fuel filters.

Can I replace my tires myself or is it like a car where I should have a shop do it? I saw some wheel protectors on eBay for like $7 so that made me think it was something guys do themselves.

It is possible to replace tires on a motorbike wheel using a couple of tire levers.I have refrained from doing this myself for years because of the risk of damaging the seal of tubeless tires to the wheel rim.Our tires,here,cost a fortune and the vendors include a fitting and ballancing service.All the best,though.

Thx, Dude. I'll take them to a shop to make sure I don't mess anything up.

I'm currently trying to start the brick and it won't fire up. I can't get the neutral light to come on so I'm wondering if that's the cause.  I know how to put it in neutral but the light doesn't come on. Am I doing something wrong or is something wrong with the bike?

Re: tire changing.  I do my own, been doing them myself since I rode dirt bikes 40 years ago.  Not sure I would recommend learning how to change tires on a good alloy rim. 

Some places will charge up to $60 to mount and balance a tire, while others will do it for free.  Ask around.  Buy the tire from the shop where you have it mounted.  Bring your wheel in so they don't have to do the removal/installation.  I had a Shinko Tourmaster installed on the front of my K75RT at a shop in Salt Lake City while I was touring last summer.  Total cost was $75 for the tire, mounting and balance.

Sounds like your gear position indicator switch is not working.  Does the starter motor turn?  Or does the engine not fire?  Will the starter turn when you pull in the clutch?

i wil just pre empt the next couple of posts from the kaumatua of our site.


we need details
turn the key on, what have you got? lights on dash? fuel pump primes?


push the button, what happens? does it turn over? cough? almost start? etc


Kaumātua are elders in Māori society. Male elders are also known as koroua (or koro for short), and female elders as kuia. Whether a person can be considered a kaumātua depends on age, knowledge of tribal history and traditions, and the presence of other potential elders for younger generations to turn to.

am enjoying your thread. as you learn, we all learn

The starter motor does turn when I pull the clutch but the engine doesn't turn over. All I can hear is the starter trying to fire up the engine. I'm thinking it's a fuel problem, in my limited knowledge. The spark plug ends on my new plugs don't match the ones I pulled out so I went to Napa auto parts and bought some that did. Here's what I mean
Could that be the issue?

Here's what the dash does:

Headlight comes on, neutral light does not come on. I hear a clunking noise in the fuel tank but it doesn't sound like a car fuel pump coming on. Is that a problem?

Yes, that is one possibility of many. See if the knob from the Bosch will fit the NGK. It's almost 2017. Post an audio file of the sound you're hearing.

[The Mighty Gryphon]

When you say the engine doesn't turn over do you mean that the starter just spins without turning the engine or do you mean the engine turns but won't start? 

If the engine is turning but not firing, are the plugs wet when you pull them out?  Assuming the engine is turning we need to determine if the failure to start is fuel or spark related. 

[The Mighty Gryphon]

Just noticed you have a 1992 RS.  If the engine isn't firing it might also be a problem with the sidestand switch.  You don't have the sidestand down do you?

This thread is starting to get exciting. That shows what kind of day I've had.

The starter spins without turning the engine. Theres a little bit of oil on the plugs when I pull them.

No, it's on the center stand right now.

Yes they fit so I'll start removing them from the cheap plugs and installing them on the NGKs. Thx
