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 PANIC 13" by OLDCRACK CYCLES, Jakarta, Indonesia

"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.
