Rabbit holes are me BMW R50/2

Yes, BMWs come with wonderful tool kits. It's said you can take the whole bike apart with one, lol. The pin wrench, I believe, is for adjusting the swingarm pivot pins? Pull one of those alloy caps off the swingarm pivot and you'll see. One of the handiest wrenches included in the kit is that flat double ended 12 pt. box wrench. The 10mm end is needed to access the 12 sided driveshaft attachment bolts.

Even BMW cars used to come with proper industry quality DIN 895 standard spanners, a very good set of channellocks, and other tools. I had an E12 5-series, then an E30 3-series. These had a very nice tool box/ tray on the inside of the boot lid. Later, I had an E46 3-series estate which had a tool roll instead. I really liked BMW cars and their tools

BMW tool kits are very good. I have used their tire irons on the side of the road when fixing a flat. Much better than nothing but not something I used if at home.

The tire irons are rather short, yes, but may do the trick on original equipment Continentals. They had quite flexible sidewalls and were pretty easy to change. Yes, the tools were very high quality, the Heyco brand, and later kits even included a feeler gauge .....

The four normal "blades" were for the spark plug gap, points gap, and valves. The funky looking one with the "U" shaped notch was for setting the correct freeplay on the under-the-gas-tank mounted remote MC. There was a groove machined into the plunger for it to fit into .....

Not may they will work and on Continentals and other tires that were put on years after the originals wore out.

I doubt I'd get a Dunlop, new or old, on or off with them, lol. Those tires are veeeery stiff.

You would be amazed at what you can do when you are 500+ miles from home and no towns big enough to have a bike shop any where close to you.

when you are 500+ miles from home

Well that'll be a while........
Project update. I'm still in that going backwards, more issues cropping up stage, but hoping I've rounded the corner.
The easy project was the tool box door lock. Some aluminum rivets from China, a bit of begging from my neighbor the locksmith, he rebuilt, re-keyed the lock, a little fab on a 16P nail to replace a missing hinge pin, and done.

Then the head cylinder saga continued.
The head with a dropped valve seat went to be rebuilt.
Lapped the valves on the "good head"


then decided to pull off the cylinders and see how they looked, was thinking; make sure the rings were free, new gaskets and done.. HAH!

Pulled the side with the dropped valve seat, that looked great, go figure.

But the rings were SERIOUSLY stuck, busted the oil ring trying to get it freed up.
So My local Mr. motor did a light hone, vapor blasted the outsides, and jugs will be fine.


A new set of standard size pistons and rings ordered. WTH sent the other head that I did the valve lap off for an overhaul too. the hive had been warning; do em both, I finally caved, in for a penny, in for a pound.
The oil pan was making a puddle, so that came off and got massaged last night. Primitive Pete had really reefed down the bolts to stop a weeping gasket, that never goes well.

I'll find or make some washers to spread the bolt loading to avoid re-warping the steel pan. then some Hylomar blue on the new gasket and back on.
Doing all this to get the Beemer off the lift for a bit so I can put the TX650 on it and see if it will be the ride for the Slimy Crud and maybe the Ozarks rally. Those efforts will be detailed elsewhere.

Wrist pins included with the Pistons ??
Other wise it can help a bit renew -- Should the old ones have some wear as the small end conrod

@ 9K miles wrist pins small ends looked fine, big ends "feel" tight.
The hive is whining: as long as you are this far, strip it down and clean the "slingers"
The thing is no oil filter, just a pick up screen (sound familiar?) and slingers in the crankshaft that use centrifugal force to capture metal debris.
Very effective at catching metal (even aluminum is heavier than oil)
SO effective they tend to be full. But I'm not going that deep, at least not this go around.
Paint on the jugs, and oblong washers "crafted" (butchered?) for the oil pan bolts.

I never had any issues with the swingarm bearings on my old BMWs, but I kept them well greased. And, I would loosen them before greasing so the grease would go into and fill them easier, then re-set them to the proper torque.

The later bikes do not have any effective access to the pivot. It's a PITA tear down to get to it, so it;s usually fubar before anyone goes in.

I’m liking your valve lapping tool.

Wish I had thought to use the little dewalt gyro activated driver. it makes going back and forth slowly a breeze.

but I was pretty careful with the VSR, kept speed WAY down and swapped direction constantly. Need to use a bit heavier fuel line for the flex coupling, some braided fuel line would be fine.
Little BM out in the shed, TX650 on the lift. Swapping threads LOL.

that is an amazing device!

 

[gggGary]

Handy tool for driving smaller screws etc.

 

[Jim]

I want one.

 

[gggGary]

Mentioned elsewhere, but put on; the new pistons, honed jugs, rebuilt heads with new valves guides spark plug threads etc. Gave the carbs a scrub and go-through and bingo bango it's runner, more to do but it's a rider.

Bombing around our hilly fenced pasture I started thinking "The Great Escape"!

The idea passed pretty quickly
