Pretty close, but it is a 1956 BSA B33 500cc.

EARL! How the heck have you been? Haven't noticed you around here much lately. How is Jean doing?

The OP posted the link where he bought it on his first post.

For the thumper fans.

1988 Harris Matchless G80. http://cybermotorcycle.com/gallery/harris/images/Harris_Matchless_G80_1988.jpg

Almost bought this bike, when I was young and dumb.

It's difficult to pin down the year, but I am going to say it is a 2006 Yamaha XJR1300. http://1.bp.blogspot.com/_St8PvhYLC4c/TQinI--Hz5I/AAAAAAAADT8/SicCkouTd60/s1600/Yamaha_XJR1300_2006_motorcycle-pictures_4.jpg

Here's my offering for a guess. Note that I didn't have to do any editing to remove badges, etc. That's just the way it comes from the factory. Well, almost. The seat is not stock.

Here's another V-12. A bit better looking. http://motorcyclephotooftheday.files.wordpress.com/2009/02/engelskqe32.jpg

And it's a V-12! http://www.blogcdn.com/www.autoblog.com/media/2007/09/jagged_edge_front.jpghttp://www.carpictures.com/pics/640/07J9A224325958A/Custom-V12-Twin-Turbo-Motorcycle-2007-07J9A224325958A.jpeg Right now, while you're reading this, there's a scion of Dr. Frankenstein out there somewhere, digging, chopping, cutting, welding, twisting auto parts into entirely new combinations. The man behind the UK shop Custom Mettle is one of them. Having a 5.3-liter Jaguar V12 with nothing to do, he added a few drinks (for himself), and go the idea to build this: the Jagged Edge. But the V12 alone, obviously, wouldn't be enough -- so he swiped two turbos off of a Peugeot diesel engine, and bolted those on as well. He threw in the middle gearbox from a Yamaha XS1100, clutch and pressure plate from a Land Rover 110, release bearing from a Land Rover Freelander, and the front and rear wheels from a Kawasaki GPZ1000RX, the the The result: 400 BHP and 400 lb-ft. On two wheels. Or, in other words: freakish madness. It's for sale in the UK, it needs some work, and it's not registered, but it's only three thousand pounds. That's pretty cheap for the chance to indulge your Road Warrior fantasies on Frankenstein's monster. Check out the gallery of images below.

In fact, Steve, just so you don't spend too much time on this ugly bastard, here's another hint: it has a French car engine in it.

We go from a very attractive bike to a very ugly machine. It is a homemade one-off, so don't worry if you can't figure out the year. LOL

1951 Mondial 125 Tourismo http://www.flysfo.com/sites/default/files/01_motorcycles.jpghttp://b296d35169b22ec514a7-3f0e5c3ce41f2ca4459ddb89d451f8d9.r21.cf2.rackcdn.com/wp-content/uploads/2013/03/FB-Mondial-125-Turismo.jpg

Jeez, Steve, I thought maybe you had quit the game. You haven't been on for a day or so. If I had known you were stumped, I would have given you hint earlier. The Hint: It is Italian.

Perhaps this CB Installation Manual may be useful: https://drive.google.com/file/d/0BwLuLxb8qHwMWVROVTc3Z25uaGc/edit?usp=sharing

Since the 1983 Venture Royale did not come from the factory with a CB, the CB unit you have on your bike is added. It may be a factory CB from a later model Venture or it may be an aftermarket CB. Either way, it was not "plug and play", thus the cobbled wiring you are finding. Perhaps you could post a pic of the CB so we may identify it? As to the "Control Unit Switch", I haven't a clue. I can not find anything labeled as such on my wiring schematic.

Doug, both of your bikes are Royales. All Royales came with CLASS. A CLASS equipped bike will not have any Schrade air valves. All First Generation Ventures (Standard and Royale) have a rear shock dampening adjustment knob; the Standard also has a Schrade air valve mounted on the same plate as the dampening adjustment adjuster, the Royale will not. Is the rear shock dampening adjuster still on your '85? Is the cable still connected to the rear shock? If not, perhaps someone has removed the stock rear shock dampening adjuster; maybe even swapped out the stock shock for something else entirely? Is the Schrade valve near the ignition switch connected to the rear shock or to the front forks? If a PO was having difficulties with the CLASS, he may have installed a non-air adjustable shock on the rear and also disconnected the CLASS compressor from the front forks and utilized a Schrade valve to manually air up the forks. Is the CLASS compressor and solenoid valves still installed? (Look under the black plastic cover under the trunk carrier.)

Did ya know that?

Thunderous.

'Monster'

Kawasaki mock-up, Project T103. Precursor for Z1. https://www.z-power.co.uk/merchantmanager/view_information.php?pId=21 The mock-up was completed in October 1968. However, Honda announced a new 750cc single-over-head-cam (SOHC) motorcycle at the Tokyo Motor Show held the same year. The Kawasaki management staff realized it was meaningless to come out with a similar model after Honda had already introduced theirs, so all development efforts on Kawasaki's 750cc model were stopped.
