For Sale: Jim Cranston R69S

This 1962 R69S (61 production) belonged to the late Jim Cranston, a long time MOA member and passionate owner and rider. This bike was meticulously maintained its entire life. Unfortunately, we were not able to secure the owner's documents from Jim's estate. The bike is in wonderful mechanical condition and runs extremely well and rides straight.

Scottie's installed a new wiring harness, and performed a full fluid service and tune up, including valve adjustment.  Some new cables and spark plugs and safety inspection.  The bike starts easy and runs nice.

Asking $12500 obo.

Replacing cam follower bores (and followers).

Replacing cam follower bores (and followers).

I really do not know how this type of damage occurs!

Looks as if it was squeezed in a vice or something. 

In any case, new follower bores and followers will be required...

A new follower bore is cut on the lathe from bronze bushing material.

The case is heated to over 250'F and the chilled bushing is inserted.

The bushing is honed to the final dimensions. Here I am using a fixed hone, however the final hone may be done with an adjustable hone and/or a brake hone.

Final fitment is done using the new followers.

Cylinder Boring and Honing Services

Scottie's Workshop has a full service motorcycle Machine Shop specializing in vintage BMWs.

One does not remove engine cylinders everyday; normally it is part of a major engine overhaul. So we don't just bore and hone cylinders; we refurbish them.

First, push rod tubes are removed and the cylinders bead blasted to remove all rust and old paint.

The cylinders are then bored and honed cylinders in the time tested way: on a boring machine or engine lathe based on the measurements of the new pistons.  Honing is done using Sonnen style parallel stone hones and cylinders will be cross hatched with a ball hone.

Pistons are weight matched and we can lighten your wrist pins about 14 grams for an additional $75.

Piston skirt clearance is determined by the piston manufacturer. When possible we prefer to use new KS pistons (many of which we have in stock).

The cylinders are then taped up and painted with high temp semi-gloss black and baked in the oven to cure.

Pushrod tubes can be cleaned and reused if desired, or we can install new ones made from stainless steel.

Machine Shop time to bore and refurbish a pair of cylinders is about 2.5 hours. We can provide services individually if you like.

When shipping cylinders to us, DOUBLE BOX each cylinder and insure them for damage.  They are quite delicate!!

We will only bore cylinders if you ship us the pistons to be used. 
We hone based on the measurement of the piston.
Even pistons from the same manufacturer vary; we do not recommend boring/honing "on spec".

We can bore your cylinders with the push rod tubes installed, if you wish.

Your cylinders and pistons will be shipped back to you cleaned, oiled and ready to install.
