I oughta make copies of the one that is so well thumbed the pages are falling out.
That price is not uncommon for that book.
See that red restoration book by Barrington?
It's in print. I bought one a year ago. $117 shipped.

Busy week, too little time for the bike.
Trying to get the tank mounted properly, collecting hardware & etc.

Control perches coming along. The throttle cam cover belongs on a twin. Covers for singles are NLA.
Today a guy on VBMWMO mentioned he had a spare
I believe the left perch shown here belongs on a R69S.
I recently sourced a correct R27 perch from S. Meyer. It needs paint.

Promise I'll clean things up better when I get some time.

That would be more likely an R69. when they became the "S"in 61 they ditched the advance cable.
To the right restorer or collector, that perch is coveted.

Thanks wire, good call. I was just reading up on that in Slabon's book.
It's good getting this all out in the open.

Wes also included this Hella spot lamp.
The switch actuates and it may not need much to make it serviceable.
Richard at BenchMarkWorks recommended Lakeside Custom Plating in Ohio for the re-chroming, after dent work.

The mirror needs re-silver-ing(?)
Also the bezel needs reforming, which I'm tempted to have a go at but don't want to make matters worse.

I'd like more information about these. Also restoration suggestions.

I gather they're not very practical, but the bling factor is out of sight.

parts...

... I've been chasing them.
The IPC is indispensible, can't imagine trying this reassembly without one.

This pic shows the hardware count for mounting the gas tank, /2 vs. /5, aka '60s vs. '70s.
From a manufacturing perspective it's a leap in inventory reduction and assembly time.



And bad news if there's a part shortage.

Speaking of which: right below the long bolt, see the two small (rusty) tubes end-to-end?
These are stand-ins for the tube I failed to order earlier which should be here soon.

This bracket in the foreground holds up the tank's aft end.
Far more complex than that of the next generation airhead.



The angled flange attached below connects to the cylinder head and is isolated from the tank bracket by a rubber donut in the conical area.

I can't speak to the origin of all that dust, definitely not OEM.

One of these?



Mein Gott im Himmel! When do you start?
Happy to help with the R27 business if I can.

Do you post info regarding your track days, where & when?
I'm thinking your airhead must sound at least as good as it looks.

any video?

Keep the information and photos coming. I recently brought home a '56 R50, quite similar to your R27. I have two other projects in the queue before the R50 but I am compiling information and references and some parts too in preparation for getting it on the road.

Thank you for taking the time to post and document.

It's complicated. My garage just got crowded again. A 71 R75 and an R80RT rolled in by accident. The R80 gets fixed for a friend and goes away but I'm falling for the R75. The R27 is in the back of my buddies garage, he's not in a hurry and the Montesa is hidden near Lake Elsinore. It isn't as zoomey as the one pictured, more like their version of a Metralla.
Corsa Moto Classica is the end of April at Willow Springs. Come out, sniff motorcycles, drink beer and camp.
No video, I'm superstitious. Too many people have crash videos.

That sounds like a lot of fun, will definitely get up there if I'm free that weekend.

Omg...

You reminded me that I have a copy of that book on the shelf above above my desk, thats in Mint/Mint condition, except that I penciled Slabon's phone number in, along with a time to catch him at home.

Well, I guess it's going to get tossed onto Ebay!

(And as soon as I do, I'll fall into an unpassupable deal on a /2! )

tools

Projects such as this provide prime opportunities for obligatory tool purchases.

Here I'm chasing polymer out of threads with a new M10x1.0 tap.



And in the pic below more thread chasing, this time with a fresh M8x1.0 tap.



It appears the PO powder coated every possible part. Personally I'm less than enthusiastic about it.

I want to remove the powder coating from the air filter cover as it's obscured the stamped text which details filter maintenance intervals, etc.



And the frame serial number is nearly impossible to read.



Apparently benzyl alcohol will do the trick while being less toxic than the alternative, methylene chloride.

powder coat

Xylene will also soften powder coat, at least the stuff I have dealt with. It is a pretty commom solvent.

thanks Icebox.
I was hoping to get a helpful response or two, haven't attempted removal before, other than with cutting tools

I've not worked woth obnoxious powdercoat before, but my first thought would be to thin it down with a soda (or other media) blaster and then polish it or hit it with a thin coat of glossy enamel (or lacquer). Of course you'd have to mask off the frame number.

My 2 pence.
