I designed a Clutch Designed Rear Set Shifter.

I was thinking along similar lines Paul. I suspect there's a spring between the pivoting heel-toe lever and the actuating arm that connects to the pushrod (can see the end of something poking out between them). So that when foot pressure is applied to the pedal it loads up the spring, then when you take the power off the gear train (by closing the throttle and pulling the clutch) the spring chucks it into the next gear.
 
So its a spring loaded shifter lever, assisting the gear lever movement. Bit different to what I expected, any chance of overloading the detent, or blowing past it.
 
NO - For Paul- The shifter doesn't assist the gear movement with a clocking spring; however, the spring is located around the foot peg does assist in centering. The shifter, itself, is threaded and mounted on a thread or worm gear peg shaft  The pressure of the spring is horizontally around the Peg Shaft against the threaded shifter mechanism and does not apply much of a clocking force but does have a very stable delayed rebound effect like a clutch.

Doesn't mean you can't use asbestos with 1" washers around the peg shaft between the spring a threaded shifter but I've found 2 or 3 modified high quality steel washers stacked with embedded grooves packed in say 90 weight hypoid gear lube with posi-trac limited slip additive is much more sturdy and reliable.

The shifter is not necessarily rear-set specific but more likely at home in that location.

I played with Tommaselli & Tarozzi rear-sets over the years - You know why I design my own.

It does have a habit of not missing a shift even if you are not deep enough into the clutch ;o)

Considering it's mechanical and considering all the modern electronic paddle shifters today - Is there a market for such device today?

It is completely different in design from any rear-set shifter I've come across. It's simple and works.

Should I bother drawing up a set of blue prints and patented it?

For you information I'm off med's and strictly into Irish Whiskey. Turning 69 in June - Broken about every bone in my body, blind as a bat, still alive, have sonar after some 55 years of riding motorcycles with many riding stories that would bore the shit outta you.

Owned many rides but I kept that SF - The only bike I bought NEW.

Ah a man of my own heart Irish Whiskey with an "e" is the only way to go much better than those poor imitations without the "e" IMHO

I can kind of picture you set up for the shift sounds like a neat way of improvisation.... me I mostly only use the clutch when getting going or at traffic lights ,,, though as I have to make sure I find the sweet spot when changing.. so can understand why you have gone the route you have as it wouldnt be as dependant on finding the sweet spot for the change.... oh at least you will be saving on clutch cables.

Oh and I like the use of asbestos washers.. .especially even in today's "politically and environmentally " friendly " climate...  :D :D

Now tell us when are you going to pull the cover and take some pic's for everyone who is not getting what you are saying  :o maybe you can charge them a bottle of single malt whiskey per viewing..

 
Brett: Fuck the "e", my Canadian spell checker took over. I'm  tired of editing tonight and doubt Aussie's can read what I wrote  - LOL.

Is there or not a "e" in "Wisk*y" ? And if you're Irish or Scott it should be spelled Whiskey.

If no "e". You are American and drink Bourbon Jack Daniel's Corn Wisky (Definitely not Barley).

Blows my mind why Americans use a "u" in Bourbon ;o)

Not the spell checker... Irish Whiskey is spelt with an "e" ...so you are 100% correct young man...

The imitations such as Scotch etc.. are spelt without the "e" Whisky... they cant make decent Whiskey and they cant spell... that is my take on the world anyways...

Have another Whiskey and fuck the editing.. I am just settling down to a nice glass of Red Breast myself as it goes......
 
Nope just a mighty fine pot still from county Cork !

I believe you had some just a few weeks ago out of my flask if I am not mistaken
 
So Ron has found a solution to a problem that has yet to show itself... wow!?  ::)

Still don't see what it has to do with a clutch in any way. ???

Maybe a quart or two of Bourbon will help me understand. :D

Blame the French Ron! It comes from a French family name in the USA.

In the UK we generally use French infuenced spelling (Colour) etc etc.
Paradoxically Americans adopted the old English way (Color) just to be different (because they can).

Simples?
 
Concourse Crap, Breganzie Enthusiasts build rides to fit us - That is to say we ride a Breganzie striving not to give up that 1/10th of a second edge to the competition.
 
Hi Ron

I am still confused, and I am just not getting it......  :-[ :-[

I am usually an "early adopter" for great ideas, but in this case I can't recommend whether it may be worth patenting as I do not understand it. Patenting something is not an inexpensive process, but if you are convinced you have a design of general motorcycle application that may sell, go for it! Lots of motorcycle quick shifter setups out there selling well  8) 8)

Too, late, I've Worked it out and have listed it and it's now Patent Pending.

I've given some credence to Ron though.

Soon you should be able to google COCKS, (Canadian Old Coots Kool Shifter)
Catch cry: Grab our COCKS and you'll soon be holding your own.
 
Paul, my understanding so far (aided by copious quantities of ethanol). Apparently it is a heel/toe rearset shifter with a spring fitted to stop it rattling. I still can't figure out if it actually does anything else.

 
Question from somebody who doesn't know much at all; on a toe/heel set-up, shouldn't the toe section be the long arm and the heel bit the shorter one?

Personal preference...

Many are equally long, the item Ron used looks like an original Laverda part, just don't know from which model.  The 125 Sport and some GTLs had such a lever, but with splines to fit directly to the shifter shaft.
