John Turner's project is slowly progressing in the workshop of Jake Robbins Vintage Engineering (Hastings)



Mats Olofsson has solved the mystery of who built it and what became of it... Built by Tim Ball:

Matchless SS80 engine; home made frame that contains the oil; single-sided Triumph 959 swingarm and rear wheel; Gilera Nordwest fork stanchions; home-made yokes, handlebars and internal controls. Front wheel = Gilera back wheel! Harley ghearbox; seat from an Indian; Promo starter and pimary drive; bus starter button; panniers carry batteries.

HOT NEWS! I have just spoken on the phone to Colin Butler, the new proprietor of Blackburne Engines…

The idea was to design an engine for people building Morgan-type three-wheelers who could not afford the £27,000 price tag for a new JAP engine (e.g. from Cameron Engineering)
The objective was to make a v-twin that would be available for less than £10,000 complete with ignition, carburation and clutch. 
The top ends ARE Ironhead Sportster, since these parts are easily available new or second-hand. The bottom end needed to be angled to allow a carburettor room to fit behind the heads – hence they chose 55 degrees – which will also look right.
The bottom end will look quite like a JAP, but a bit “fatter at the front” (i.e. on the timing side) – in other words, sticking out about an inch more – since it will have 4 cams. 
The crankcases have been designed, and mocked-up. The first batch is currently being machined. They have decided to machine from billet since, with all the CNC machines set up, it will be more reliable (no duff porous cases) and so more economic.

The engines will come with non-adjustable electronic ignition (since Morgan racing specifies this) but this can be changed to adjustable – and will have a more reliable oil pump from later Sportsters such as the 883.

There will be three price options: 
1. Complete engine with carb, ignition and clutch: about £9,000
2. Crankcase kit for about £4,000 and buy new Ironhead Sportster components from USA for about £2,500: Total: £6,500
3. Crankcase kit for £4,000 plus buy second-hand Sportster engine for about £1,000 and transfer components. Total: £5,000-£5,500
4. Even cheaper for motorcyclists, since they will probably need neither the clutch (and can just put an engine sprocket on) nor the S.U carb.

The first examples should be ready to fire up in May; the first batch should be ready by August, ready for the Morgan show at Malvern in September.
He will keep me updated, and may send some pictures or put pics of the mock-up on the website. http://www.blackburneengines.com/

Brian Shackleford has been in touch with pictures of the progression of his special that uses Harley, BSA, home-designed and machined parts plus.... intriguing!

DOUBLE MAC - Allen Millyard's 698cc 50-degree Velocette v-twin special progresses:

BUT... here's something odd: An Argentinian artist by the name of Patricia Couto of Buenos Aires has produced a drawing of an apparent Velocette prototype from 1948 that is almost identical. It is labelled "Punto alto Velocette 698cc v-twin-1948" meaning "Velocette's high point" a mystery ... did Allen reconstuct a prototype? No, the drawing was produced about 3 weeks after Allen posted his picture, and is obviously copied from it, with altered lighting. Mystery solved!: Patricia Couto's page

"This interesting 'special' consists of a 1927 James 500cc overhead-valve v-twin engine purchased, mostly complete and in very good order, around 18 years ago in Harrogate. The only part missing was the rocker box cover, which proved so difficult to find that a new one had to be cast in aluminium. The frame is from a James single but has been modified, the top tube being lengthened and a 'U' shaped bracket fitted at the front. Forks are from a heavyweight Levis; the front wheel from a Velocette; and the rear wheel from a heavyweight Triumph. The fuel tank and three-speed gearbox are James. Other noteworthy features include custom-made exhaust pipes; original 1930s James-type silencer; and an oil tank copied from that of a 1931 James v-twin. All other parts date from the 1930s. We are advised that the machine has not been run since rebuild was completed.

The build has gone incredibly quickly, as he posted daily updates on his Facebook Wall: https://www.facebook.com/allen.millyard In only a MONTH (Oct 18th to Nov 19th 2018) Allen built this complete one-off engine!. Staggering quality and beauty! Crankcases are welded rather than cast.

Siannu in Rusutjarvi, Finland created this machine. Clck on piuctures above and browse Flickr archive for more pictures.

Adbertised on ebay in August 2018, for £9,500 it was unsold with NO BIDS. Let us know here, if you buy at and I will cover any future modifications.

Here is the accompanying info:

If you are searching original or museum piece this is not for you. I do not have any papers or documents for the bike but engine has run about 3000km  within last 5 years. 
Frame is Norton plunger modified to take big V-twin engine.Gearbox,wheels,tanks,toolbox,and clutch is from Norton as is oilpump which is Norton inter/Manx type.Front end is unknown but may  be from Horex S8.
Cylinderhead castings(iron) are MFC made as is aluminium cylinder barrels and timing cover.Rockerboxes and oilpump housing  are home made.Magnetos are from BTH and with manual advance.
Engine is one off made by me with Harley sportster evo crank,british type drive side bearings ie. ball and roller bearing,timing side is HD needle bearing.
Pistons are 85mm HD ones.Compression ratio is modest but still "adult" is needed to kickstart the bike.I have added photo of the longer conrods(with omega pistons) which with you can increase compresson ratio over 9:1.Last foto shows similar timing gears and roller followers as this engine has.There is many homemade parts on the bike so expect to have some work time to time but main construction should be ok .Paint work is not good.
Reason why i am selling this as a project is that there is several oil leaks and rear plug needs cleaning more often than front one,reason is maybe piston rings.Carbs are Dellorto 32mm and best settings still to look.All gears are selectable and clutch is working,engine runs.
Will sell worldwide but buyer to arrange freight.More fotos on request.
Thanks for looking!



Brian Shackleford is building another very similar engined bike using a Harley/BSA combination of parts. Brianb sdays he has now ridden the original SHACKLEFORD 1200 miles with no problem - not even needing adjustments!

"Don't Panic13" by Oldcrack Cycles, Indonesia.... Source: http://naikmotor.com/77914/ini-motor-kustomfest-indonesian-attack (press translation button)

Motorcycle Name: Don't Panic 13 
Name Builder: Rudi Siswoko 
Concept: Old Tracker

(HD WL750 1948)

The motorbike to be brought to Japan was inspired by the motorbike era in 1920. Besides its old-fashioned appearance, this motorbike was intentionally built to show engine performance. Taking the base of the 45ci HD engine, Oldcrack modified the engine using Japanese car parts combined with Triumph gearboxes.

"The manufacturing process takes a little time and energy. The engine base that we use is only a side valve and the rest is overhead valve, we have to make our own using components in the Indonesian market, "Rudi opened.

Some of the engine parts made by Oldcrack include burring (barrel?), cylinder head, rocker arm and intake. The rest use motor parts or cars such as pistons from Mitsubishi cars, valves from Japanese cars and Mikuni 28 carburetors.
