Look under K100RT,  Fuel Supply,  Fuel tank attaching parts,  Line item #5

P/N 16 13 2 307 467    AIR ACCUMULATOR  $2.66

Postage will be about $7

[Laitch]

£7 for the part, £45 shipping to the US. I guess it works both ways!

Postage will be about $7

I just checked. It said $2.66 and free shipping when I filled out the order.

Holy Mackerel!!!  I've spent more than I like to admit there, and never got free shipping.

Then buy an air accumulator and get a thrill!  :yippee:

All my bricks have one already.  I am in that Nirvana where none of my fleet needs anything.

lol. Mine needs to run properly!

Time to buy another brick.

Ahh that time, when one has a properly working bike without ANY ailments. For me this kind of a nirvana is dangerous as it usually means a slow degradation of the love... At least according to the wife, who thinks, I'll get rid of any bike, that does not need any more TLC :) In my opinion it is just the compulsory small ads scrolling that takes over from the 'reading up manuals all night long and asking stupid questions all over the internet' :)

No such thing as stupid question, just stupid people that don’t ask to find out...

Hi.
Report back from the injector cleaning place.
One never worked!
Now all working and within 2.5% of each other(?).
I’m guessing that’s good?
The guy said that they will be fine.New oil in gearbox and final drive,today, just waiting for injectors to arrive. New ‘O’ rings and clips are here. Quick question...
Getting it all back together... pulling the injectors out took a fair bit of pulling.
Do I just put them back on the bar, connect them to the electrical plugs, then tighten up the 2 bar bolts and let the bolts do the work? Or do they have to be pressed in? I’m guessing the new runner o rings will make it difficult...

[The Mighty Gryphon]

Put a little Vaseline on the o-rings and in the bore where the injector goes. 

As far as Nirvana,  Ilsa still needs a couple things; a lower fairing bracket needs to be installed, and I have a bad connector in the driving light wiring.  I also want to look at the monkey nutz and service all my starters. 

The good news is that I don't need any parts to do any of the jobs.

Hi. Got the rear drive off.
Do these look ok?

No.  How the pluck did this thread get 8+ pages of posts?

The driveshaft socket splines are close to failing, depending upon how aggressively the moto is ridden. The final drive input shaft splines do not look as severely worn. Another photo of them illuminated more clearly is needed.

Yikes!  That drive shaft is not long for this world.

[Soggz]

Hmmm...you got a spare one?

[The Mighty Gryphon]

No.

You think I’ll get many miles from what you can see?

Here you go, sir.

What makes the splines do this?
Is it from sitting long periods of time?
Where does the lube go?
Confession, I never looked at them on my first ’85 K100RT and I sold it with 100k miles.
Valves were not checked until 80k miles and in spec.
Maybe I got a Wednesday motor?
Debating if it is worth all the work to check on the current ’85 that only has 23k miles...

[The Mighty Gryphon]

It works better if you orient the part so the light reflects off the top of the splines.  The width of the flat surface at the top of the spline is the easiest way to gauge spine wear.

Having said that, your final drive doesn't look all that good either.  It looks worn enough that putting a good shaft on it will prematurely wear the shaft.

[Chaos]

I'm guessing bad metallurgy or engineering. Seems that if the splines are not lubed about every 20-30k with a good moly based lube they can wear out.  Perhaps the one biggest K Achilles heel. Replacements are scarce and repair is expensive.

Idleness is not the cause.  When the shaft rotates, there is a very slight change in the relationship between the parts of the universal joint that results in a very small linear motion in the end of the shaft at the final drive.  The splines are designed to allow this linear motion, but they need to be lubricated with a lubricant capable of handling extremely high pressures.  Molybdenum is one of the best and is why brick owners use high moly content lube on their splines.  The normal lube interval roughly matches the tire life of the rear tire, so that is when conscientious owners lube their splines.

That you didn't lube your splines for 100,000 miles probably means the next owner of your old K100RT probably had a situation similar to what you're facing now.  I hate to say it, but karma comes to mind.  As far as valves, depending on how hard the bike was ridden, it isn't surprising that they didn't show a lot of wear.
