Bikes are rolled of the trailers at first daylight. A cold but sunny day, perfect for off road riding. The frost had made the sections slipery so we where going to have an challenging ride....
It turned out to be to challenging for my ride, I had to give up halfway. I lost power and could not get the engine to rev.....I suspect the mag timing have sliped on the taper.
Bikes lined up in "park fermè", not allowed to be touched until ten minutes before starting time.
A Jawa rider splashes thru a small stream.
Lucky I had to give up halfway.......not so much washing....
I went home early so I don`t know the results.

When we started with old bikes for more than 30 years ago, we often stumbled across parts for bikes we had never heard about.
There were still some farmers, blacksmiths and repair shops with old timers who had a different attitude to stuff than we have now. Nothing was wasted, this was before wealth and oil money had changed the view of things.
We went around asking for old motorcycles and bits; often we pulled a lot of “scrap metal” home. The bikes and engines where skillfully identified with the help of a copy of “Illustrated Encyclopedia of Motorcycles” by Erwin Tragatsch. But some bits remain a mystery to this day…..
Some of the parts we found puzzled us, they were not supposed to be here…..bits for bikes never sold in Norway. We had heard of sailors bringing bikes home, but why make a Rudge multi gear compressor with a FN four cylinder petrol tank….
After a while the mystery was solved….Just after the WW1 a local shop owner had bought two or three train wagons filled up with mechanical stuff. The story I’ve been told are that there was auctions held by the English army. They sold of big lots of damaged vehicles and parts collected from the front and nearby villages.
A big auction was held at the train station at arrival, and a lot of homemade farm devices were created.
Most of the parts we dragged home have found good homes all over Europe, but I still have some of these parts in my workshop. I like to have pieces of history to look at.
Can anybody identify this engine? WFW it says in the casting. I have been thinking of Wanderer but I have not found any proof…..Would be great if anybody knows…..Please send me a mail if you do.

We have already got frost in the mornings.....Motorcycles in Norway seems like a stupid idea now.
This is the time to relive some holiday memories, so here are some photos from Musèe de la Moto in Marseille, France.
I am in the mood for some Chianti and pizza....That's why I only look at Guzzis today......and I have this thing for drum brakes, scissor dampers and racing bikes.....

I have been working on a Ariel HS engine this weekend. Been meaning to do it for a long time........and now I have some plans for it.........
Ariel HS, made from 1954 to 1958. HS stand for Hunter Scramble, Ariels moto cross model. It`s a 500 cc push rod single with aluminum head and cylinder.
This is howe a HS engine look like.......
Now I need a fast engine.........Well, they where fast fifty years ago....
Some of the work was done years ago.....
The crank needed a good wash and polish....The big end bearing and small end bush had to be replaced.
This engine had only ball main bearings (3). I use two rollers and one ball bearing. Takes some time to shim up the crankshaft.
I have got an new liner in the cylinder so it`s back to standard (81,8 mm).
The pistons from left to right: HT (trail), VH standard, HS high comp.
I used the high comp one.....
NOS Hepolite piston rings, comes with warranty slip.
Filed the gaps to racing spec......
The important cam shaft. Ariel singles use only one single lobe (from 1951) for both valves.
The left one are HS MK1 the right are VH standard.
Apart from the grinding the HS cam have a hole down the centre of the shaft and a smaller hole through the base of the cam.
You can use the HS cam with standard cam followers, but I will use the HS type for more performance.
A good start..........Have to order some bits from Dragonfly motorcycles.

The best thing you can do on an Saturday afternoon is to visit a friend for some coffee, cake and motorcycle talk. A look in the workshop to see the work progress is a must. Especially in this work shop......Just some random pics to give you an idea:
Manx Norton, NSU, Wandrer, JAP........I think I had kept them in the living room....
An AJS 7R engine installed in a road frame. Will make a hell of an desert racer. Norton Dominator engine behind the bike.
V twin JAP engines waiting for some TLC.........

Olav have put his race face on......Is it badger fur on that jacket?
Blue comb and rolling tobacco......Only found on experienced racers!
I think Olav have to visit the Harley dealer on Monday......"high lift cams and a pair of WR cylinders, please...."
