Hi gabszab (sorry, I don't know why I have the urge to say it backwards)

Any chance of a photo, I'm considering something similar too.

Dave, probably it is because of the way, you are used to saying names, first names first :) Call me Gabriel, that is the same over here or in the rest of the world :D

I will get you some pics, once I am back at home, in the meantime this is the bar riser, I have bought (funnily enough the price has risen since by two dollars) - https://www.aliexpress.com/item/Anodized-2-Inch-Pivoting-Motorcycle-Handlebar-Riser-For-7-8-22mm-fat-handleBars-Clamp-Universal/32963182766.html?spm=a2g0s.9042311.0.0.190b4c4dP1OIy6 Do not buy this however, as it is not precisely machined, and the hole distance is 1mm or 1.5mm off, I very nearly stripped the threads on the triple tree trying to bolt it on. The seller was not helpful at all, at the end aliexpress had to step in as he was getting aggressive, strange behaviour from a professional seller...

Hi Daveson, finally I managed to be next to the bike equipped with a camera, so here are some pics of the setup...

The valve cover was wet the last few times I walked past the bike. First I thought maybe the gasket was letting oil seep through. I found a few drips hanging in the edge of the tank, so I removed the tank to investigate where the gas leak is leaking out. There's seems to be a pin hole somewhere in the tank. I just can't seem to find it. It leaked enough to create a puddle of gas on top of the motor.

What a mess.

There are ways to repair that. The most certain way is to coat the interior of the the tank but if you can find the leak, other methods might also be effective.

Here's a thread that describes several methods.

Today I learned the hard way not to poke one's phone into a nearly full tank to video the return line. The video is OK, the phone is soaked with petrol and the display became somewhat discoloured. Fortunately it is accident insured :)

The reason I have gone into such antics was to see why is there the loud hissing noise that annoyed me for a long time. There is no return line down to the fuel pump and the petrol from the solid pipe end is hitting first the 'burrito' and the wall of the tank. I was just wondering, if anybody cut that line shorter, as it is not connected to that collector thing (the burrito) it is facing sideways and there is no barb at the end? See the video, sorry for the shaky end, as that was the moment I have realised, the top of the phone is taking it's petrol bath :)

You don't want to do that because it helps with the fuel mileage.

Oh wait... This could explain, why I did not succeed with the other attempts to lower my dreadful fuel consumption?

That groundhog Phil is full of crap ... snow and freezing rain here, so a good time to lube/check DS/FD splines and swingarm bearings. Not perfect teeth on the shaft, but good for a couple more season's of reasonably sedate motoring.

Strictly speaking, Phil only violates his contract if winter doesn't end before March 20. If weather starts moderating before then, you'll be down for rodentslaughter.

OK, freely label me as a "rodent-ist", as I don't distinguish between groundhogs, marmots, or whistle-pigs .. they're all Union with a super lucrative collective bargaining contract that let's them get fat and lazy. They have bad teeth too! ;)

My K bike is in about the same situation as yours, though I went all the way to the clutch. I also took the opportunity to clean up and grease the needle bearings on the clutch lever back there. Happy to find my splines as square as ever . . . but not so happy to find gear oil in my swing arm. I did the pinion seal on my final drive a few years back, but have no appetite for doing the one in the nose.

Couple days ago, not wrenching on the Brick, but visiting several of our Maryland Senator's, Delegates, and Chief of Staff to promote safe multi-modal transportation (especially SB804, SB354, SB787). This also includes the awareness and safety promotion for motorcyclists as roadway users at risk from caged vehicles. Banding together!

Got new monkey nuts from Euromotoelectrics and installed them tonight with helpful directions from this thread:  http://www.motobrick.com/index.php?topic=3009.0

I found the hint to use a transmission alignment bolt to be helpful, also lubed them with 3M silicone paste.

I've found that Torx bits can sometimes be used to remove stripped out Allen screws.

I used to have about a dozen of those pivots that I got in a bunch of parts from a breaker.  After several years of giving them to anyone I could get to take one I shitcanned 3 or 4 of them not two months ago.  Damn!  Isn't that how it always works?

There is a bunch of them on eBay for 15-20 bucks.  Search on BMW K100 swingarm pivot pin.

+1 with TMG idea with Torx bits, penetrating oil, and walking away from it for a day to let it soak.
I've also extracted a stripped FD fill plug with a coarse thread screw extractor, after drilling out the plug head to size. Lot's of penetrating oil.

Not a brick, but I broke a 5mm stainless in a lug, No Bueno! Oiled it, walked away, complained I hate Maryland, and returned hours later to surgically cut a slot, and ooze the bolt out like 007 defusing a Nuc. Then dance around the workbench like a savage, all happy that "I Am Da Man."

Well hell. Anyway, to clarify, it's not the thread that's stripped, it's the socket for the Allen key. Don't know why they make it so soft, and I really have to get more careful about seating the Allen key in there -- this is the second time this has happened to me IIRC. Also, it's not a problem of pulling it, I only discovered the stripped situation when I went to torque it up re-installing it.

Not finding so many of them on Ebay (lots for Airheads for some reason). For $40 (including shipping) I can get a used one from England, or for $60 plus tax I can get a new one from Max. Thinking it over.

Maybe I'll try cutting new fitting in by driving a Torx bit in there. It's not like I'm taking if off more than once every year or two.

Is this what you're looking for?  K75 and K100 use the same part as far as I know.  The part numbers are the same.

I found one for even cheaper. Or rather, it found me.

Installed the Reynolds Rack, purchased right here on MB shop-o-rama.
Take away: The rear bolts are a pain, as the spacing to install is very tight and mounting a Z-bracket means making custom length bolts. I only wanted 1 sidecase, so it was only a 2 day job. Super heavy duty once installed, and I would not hesitate to belt the baby seat carrier to it and run errands at highway speeds.

Seriously considering a smoke array for the horrible tailgater's here, 4 on each side would do. I also have a small metal tube to deploy a phosphorous flare spread that could cover about 2 lanes, not much, but attention getting. Has anyone done this mod without cutting the rear loop, or interfering with the rear gunner swivel?

Fired it up after a 3 month hibernation in the back of the garage.  Cranked over twice and ran perfectly, didn't even smoke.  Tires only lost a couple lbs each, took it for a quick couple mile spin.  Felt really weird because (a) I've been riding the Ural the last 3 months and it is a prehistoric Flintstone's contraption, and (b) I just finished a 20 mile stint on my drop bar gravel bike before I hopped on the K, the contrast going from a 20lb pedal powered bike to a 500lb motorbike was, well, a bit of a shock.  Gotta say, this K is freakishly reliable, I think the trick is not letting anyone with a sawzall get near enuf to loop it.
