20 Feb 2013: Musket 998 Out on a road test!! Turn up the volume and boost the bass, says Aniket.

6 Feb 2013: Australian engineer Ian Drysdale has a history of building unique motorcycles: Dryvtech - a 2-wheel drive, 2-wheel-steering off-road design, a v8 alpha-romeo-engined machine; and his own design of 750 and 990cc 32-valve quad-cam v-8 bikes, using Yamaha heads and pistions; he was also involved in the development of the Carberry Enfield v-twin. Now he has developed the American-style cruiser engine, called "Godzilla". It is still an air-cooled pushrod engine, but has some unusual features. It is a 50-degree v-twin with a dry sump. The design incorporates features developed in an aircraft engine the Pratt and Witney 72,000 cc - yes - 72 litres! - "Corn Cob" from 1945 - a 'master and link" type con-rod arrangement; a camshaft with conical or tapered profiles, driven at 90 degrees by bevel-drive. It will have an integral supercharger with adjustable boost. Here is a pdf article: http://www.eurospares.com/graphics/engine/DrysdaleGodzilla.pdf

Allen Millyard's creations:

This is the "SS100" made from two Honda ss50 engines...sounds incredible!...like a much bigger bike. Allen Millyard has made other incredible machines...a 4, 5 and 6-cylinder Kawasaki 2-strokes, a 1600cc V8 made from a Z1000; a 2600cc v12 made from 2 z1300s

Article: http://www.telegraph.co.uk/motoring/motorbikes/2728341/All-his-own-work.html

Published on Youtube Feb 4th 2013; "This is the first test run of my 5 litre V Twin engine based on two Pratt & Whitney R1340 aircraft cylinders, all other parts are hand made including the crankshaft, con rods and crankcase wooden moulds, the crankcases were then cast in aluminium. The engine runs a dry sump with twin pumps, twin SU carbs, points ignition with manual advance / retard and twin plugs per head." The 1340 refers to cubic -inch capacity of the 9-cylinder aircraft engine, which equates to 21.96 litres - see Wiki info http://en.wikipedia.org/wiki/Pratt_%26_Whitney_R-1340 each cylinder thus displaces 2,444.44 ccs, ...Two of these cylinders together displace 4,889 ccs.

Here is a build blog for this v-twin engine, http://www.warbirdinformationexchange.org/phpBB3/viewtopic.php?f=3&t=47546

Dominic created this 140cc v-twin from a Honda CT70 Story: http://chalopy.blogspot.co.uk/2011/06/ct70-v-twin.html Allen Millyard's SS100 sounds ten times better...see above.

It accelerates amazingly!

21Jan 2013: FANTASTIC NEWS! Only a month and a bit after getting the engine running, Aniket Vardhan has completed the prototype 998 Musket! What a fantastic piece of work ! Congratulations to Aniket for his persistence in producing this dream engine! Just look at it:

As of today, this is just up on Aniket's Facebook page...so new it's still to be announced on the website! http://www.musketvtwin.com For a quick summary of Aniket's story, go here; http://cyrilhuzeblog.com/2013/01/04/the-all-new-998-cc-musket-v-twin-engine/ see below for the video of the engine running without exhausts.

16 Jan 2013: Yippeee! Aniket Vardhan has completed the development of the 59-degree 1000cc double bullet (Musket) V-twin engine http://www.musketvtwin.com

This (variously either 700cc or 750cc) 90-degree v-twin presumably made by Herbert Ammon, is formed of two modified 350 top ends - from a Horex Regina, with specially-made barrels, on a 1955 Horex Resident crankcase, inspired by the original Albert Petith creation below

V-Twin Horex. This shows Alfred Petith's original special (with a smaller angle between the cylinders) built in the 1960s.. He put two 350 cc top ends from a Horex Regina onto Horex Resident crankcases, to make a 700cc v-twin.

"Alfred Petith also for his "Büffel" 700 special. Petith was a former employee at Horex, working in the research and development center, and had bought many spare parts when Horex was absorbed by Daimler-Benz in 1960. For his "Buffalo," cylinders, heads, and pistons came directly from the 350cc Resident. Centercases are from the Resident, but are heavily modified, rewelded for the accommodation of two cylinders. It has a homemade crank with a crankpin for two connecting rods. To cool down the rear cylinder, which is blocked by the forward cylinder, Petith installed a multi-step oilpump for more flow. The clutch is originally from a Resident 350 and was a weak point, as it was overstrained with the power that has been increased to at least 40HP. A complete new frame was designed, but the result was worth the effort, since the frame nestles so nicely around the elegant engine. This one-off motorcycle reminds us that there were still dreamers and motorcyclists of conviction in West Germany during the 1960s when most manufacturers had abandoned the two-wheeled market." .....from http://www.motohistory.net/news2008/news-mar08.html

ROYAL ENFIELD ARE CONSIDERING DESIGNING A V-TWIN

Following the success of the Carberry v-twin and the interest in Aniket Vardhan's v-twin enfield designs, Royal Enfield is considering designing its own model. This is bad news for Anikhet's Musket V-twin...and we have heard nothing from him for several months now (since March 2012).

Two videos have recently appeared showing yet another home-made v-twin based on Royal Enfield parts: "The motor, in a beat-up looking old Bullet frame, runs and sounds great. It's fascinating looking at the solutions to such knotty problems as how to route exhaust pipes and where to place the carburetors."

"Builders Anand Bhalerao and Dean Fernandes of Mumbai spent four years creating this 45-degree V-twin from Royal Enfield AVL motors. It has wet sump oil circulation and rocker adjusted pushrods."

700cc MATCHLESS V-TWIN MADE FROM TWO 350s by Henk Wierenga from the Netherlands:

PAUL BRODIE BACK-ENGINEERED THE 1919 OVERHEAD-CAM EXCELSIOR 1000cc V-TWIN BOARD-TRACKER. SIX WERE ORIGINALLY MADE IN 1919 AND ALL DETROYED BY THEIR DESIGNER WHEN HIS FRIEND WAS KILLED ON ONE.

In 1919, the Harleys and 8-valve Indians were circuiting at 100mph (with no brakes, clutch or gears) and the Excelsior OHC machines were going 120 m.p.h. plus...

Brodie first made a mock-up sohe could cast the parts, then made a working model, and will make 10 working models, tnat will be for sale at around $130,000-$140,000 each, since they will each take a year to make.
