I have heard of Givi luggage systems…..I have also heard of bag in box wine, mobile phones and GPS…..Probably overrated.
Slightly modified Husqvarna/JAP, nice!
Check out this video from Skagenløpet:
I don`t usually follow men into the toilet…….But I got invited to see a paper roll holder that I would like….
I think my friend tried to shook me…..He knew that I was going to visit him. I don`t believe that this is the normal storage for the engines. Well I hope so…..
We could not go to Sweden just to pick up an exhaust pipe. We had heard about an auto jumble In Örebro…..The saying was that it is a god place to find motorcycle parts…..Luckily I had made some appointments and deals before we went. The only thing I bought on the market was a cup of coffee. But then again you never know….
Some interesting engines.
A “cable remote” Lotus made me stop. I managed to tear myself from it when I saw the price tag.
The trip took 24 hours…..4 hours on a ferry….12 hours driving… 4 hours sitting/sleeping in the car….3 hours at the jumble….1 hour eating…
Last time this Speedway bike was feed with methanol was in the winter of 1982. My brother and some friends took it out for some ice racing. They ran out of methanol at high revs and caused a valve to burn. So the bike went into the cellar…..
Sorry state....
Well, don`t time seem to fly when you have fun? `Nearly thirty years later my friend Speedy Gonzales Gunnar starts to bug me for JAP and speedway parts. I don`t want to part with stuff I might need so I had to get the bike together.
So where did I put the seat and mud guard?
And guess what, the valve is still burned…
Methanol tanks for my Staride/JAP speedway bikes, ca 1950. Will post some pictures of the rest of the bikes later....
Some more photos from my old albums….
In the early eighties a few of my friends and I got hold of some speedway bikes. Used, or more or less used up speedway bikes was going for little money. I paid for a running Staride/ Jap 500. - NKr (£ 50, $ 85.)
A friendly farmer let us have a field for practice. But complaints from neighbors and a campsite made him go back to growing potatoes.
The bikes were also used on a lake in the winter time.

This is Arild trying to broadside a two valve Jawa…..

Home in the cellar……spanners flying…..probably did more damage than repairs….
The Staride/Jap.
I still got this bike….If you notice the rear tire: Dunlop TT100, we were probably going to do burnouts in the street…..
None of us made it as proper speedway riders. But I bet we had more fun on the bikes compared to the PlayStation boys are using nowadays….
Some photos from a English bike rally, early `80`s.
We were impressed when a local man arrived with this homebuilt bike. First time the special was out, and straight for the rally.
If I can remember correctly he was running the bike on methanol, burning one liter per kilometer......Not made for touring.
"Total loss" speedway type lubrication is rarely seen on the highway, but there are nothing like the smell from Castrol R40......

The frame are Ariel, probably WD, JAP 500cc speedway engine, forks from Norton, Suzuki tank, Burman gear box and a "banana" seat to top it of.
I don`t want to be accused for writing an interior blog….So here are some JAP engine photos.
My friend “Speedy Gonzales” Gunnar is deeply involved in his speedway project. He phoned me up and told me that that they had discovered that the cam in the JAP engine was too hot, probably some kind of “long track” cam ore special grind.
I told him that the whole point of a speedway engine is to get it hot. The whole idea of putting an methanol burning engine in to something looking like a lady`s bicycle frame……….Well , we are not talking “health and safety” here….
But I do have some cams. There are to my knowledge not produced any touring cams for speedway engines but in a box marked ”Cam for cubby middle age man, just a little bit fast” I found what he was looking for…….(I am joking…..He is not that cubby…)
The engine is overhauled by a very skilled mechanic….
This is my JAP/Ben air compressor. Used by Shell to pressure test petrol tanks in the `50`s and `60`s. I use the compressor on race meetings and rallies.
It`s important to have period air in your vintage bike….

My always enthusiastic "build for speed" friend Gunnar are at it again ......Speedway! And Jawa won`t do, only JAP are good enough for connoisseurs....
The lucky lad have got himself a late `60`s short stroke 500...
So when he was supposed to help me at Kala raceway....Of he was with money burning in his pocket ...... He found exactly what the needed......
"An offer You can`t refuse".....Looks like Gunnar are offering a to low bid. The seller and buyer are both embarrassed.......
The future`s so bright, I gotta wear shades........
Keep it like this..........safest!
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.........
I have been working quite a lot on the Ok Supreme. My first plan with the engine was to overhaul the magneto and check the cylinder and head. I wanted to leave the bottom halve alone.
But it is not supposed to be easy, so when I saw the state of the cylinder and head I knew that the crank cases had to be opened…..
The engine has not the usual main bearing set up of ball and rollers. There are long rollers straight on the shafts. So when you have worn shafts……you have trouble…..
The shafts has too much damage for grinding and “spray” welding don`t work well with rollers. New shafts are the only solution.
The JAP speedway engines have the same set up but not the same size…..So where can I find new shafts? A Swedish friend pointed me in the right direction…..There was a place that could help…..After a phone call we agreed that I took the crank apart and sent the shafts and bearing rings to get the everything to the right sizes.
Need some pressure to keep the crankshaft in place when unscrewing the big end nuts.
Time for wood and mallet.....Hit me baby, one more time.....
There were more problems…….The rollers of the big end bearing had “eaten” a 3mm groove in both sides of the crank weights…..Another phone call and everything are on their way to Sweden.
Need a good washing.......
A new JAP V twin engine......I think I can find use for a few somewhere.
There are different options of heads and ignitions.

I think I can spot some oil on his thumb, trustworthy on a engine manufacturer.

A modern Brough Superior?
A BSA with a single JAP engine. Supermotard by the looks of the tires.
Throw out the HD engine and install a 95 bhp JAP instead.
This Featherbead/JAP will wake up the nigbors all ower town.
