Guzzi gearbox conversion

[TwistedPatience]

This is pretty much sorted now so if you want to change your reliant gearbox for a moto guzzi one I've almost finished the final design.

This version will be based on the casting used on the voyager but will be fabricated so it's cheaper to make.

This is a dual offensive.

The Pointy Helmet UberHelmet Department has already flown a number of sorties (below radar)
and is in the company of Mr. Twisted Patience.

We WILL DEVELOP EVERY ASPECT OF WHAT IS FEASIBLE.

WE WILL COST IT ALL UP AS A CAD EXERCISE.

AND BE ABLE TO PRODUCE IT.

This MMM forum will keep you informed on progress.

This is going to slow down and send the costs soaring for my trike.

But this has ALREADY sucked in ALOT of diverse WOULD LIKES from THE CLUB.

I have already, at 5.55am today, dropped off paperwork for my fabrication engineer.

I will hopefully get some feedback today.

Around twenty e mails have bounced to and fro, on this already.

Please post your thoughts on any aspect of this.

IT

WILL HAPPEN.

Depending on what people would like out of this concept.
We will build this into the project.

Been up at work all night....Lined up today's offensive already.
ACHTUNG BABY!
We're on the case.

Time for some zzzzzzzzzzzzzzzzzz's

A ****ing QUASAR!!!!

A small world eh!

So ...what are we talking about here? An adaptor plate to fit a Moto Guzzi auto gearbox to a Reliant engine? If so that could be hugely beneficial to a lot of people -I'm thinking disabled guys especially. If it works, that'd be a big step forward in the triking world. So which Guzzi box does it use & how readily available are they?

[TwistedPatience]

Seems that all guzzi gearboxes are the same, well for the large ones at least. Am not a guzzi specialist so if anyone know any better PLEASE let me know ASAP.

This project is a manual 5 speed to reliant engine, it uses the Guzzi Gearbox Flywheel and clutch thus giving you a constant mesh 5 speed.

Not found an automatic but if someone needs one and can find it I see no reason why it can't be adapted to suit.

Looking to build a DIY kit at low cost ie you find the guzzi parts, we will do the rest.

Doc.

"I would like to take your point - and drive it home!"

COULD ALL MMM WEB FERRETS
KEEP YOUR EYES PEELED FOR AUTO BOX INFORMATION THAT WE COULD UTILISE.

It looks highly probable that we can produce a very pretty polished or satin finish, stainless steel adaptor.

Yes.

In answer to the idea put forward.

A RELIANT BOBBER BIKE is one of THREE concepts squirming in the box.

I am cataloguing this project as-

FZ 142


As with ANY design project. We will meet with some blind alleys.
Part of the game is to tick them off and develop the best options available.
At every stage we will be costing AS A FEASIBLE bit of kit.
We are not looking to wheel out something shiney and prohibitively expensive.

All I can say is...
All options are looking VERY POSITIVE.

Doc is nothing but on the ball.
At my end I am in direct contact with my production Dept.
24 hours a day.

SHOULD BE AN INTERESTING SUMMER!

[morrag]

Yup, just as you thought, still UGLY!!! with a capital UG.

[The pointy helmet]

Forget the old Ug Voyager.
We are still moving along with the gearbox conversion.

Reliant trike.
Bike gearchange.

You can STICK yer stick !


The CAD exercise is on the back boiler.
The cost of the billet aluminium is so prohibitive that few people would consider the option.
It would cost a certain amount to program the details.

I am spending money all over the place, so have to duck out on spending on this for a week.
Working out a channel to obtain the Guzzi parts required.

As my trike is the first one to sport the GuzziPig set up.
We will update with photos as it happens.

[morrag]

I am trying to fathom this project, Guzzi 'boxes are like 'hens teeth' to obtain, the conversion plate is expensive to make, and you don't get a reverse gear even, wheres the point, other than a dubious value foot change? and I have no doubt if your energies were expended on that as a project you would come up with a passable Reliant foot change conversion! so there may be a more practical way forward, oh and its still ugly!! Morrag

[TwistedPatience]

Moto Guzzi gearboxs don't seem to be that rare now except the auto of course, have found several ranging fron £75 up.

As for the conversion plate being expensive, I have just redesigned it to be cheap, as the original was a cast alminium part and as such expensive, you could use a CNC on a solid block (which would cost in the region of £100-200 alone) but at about £100 per hour for CNC that's out but there's always more that one way to do a job.

Hiya Morrag.

Trying to fathom your posting.
We are not using a Guzzi Convert auto box.

What's UG?
Voyager is hyperuggliness on an effin stick.

We are not wheeling out a Voyager.

We are using the concept of the Reliant engine linked to the Guzzi box.
Me mate saw these flying round the Isle of Man, years back.
They went like stink.
We are taking the one part of the Voyager that made sense.
Shedding the ££££££££s and lbs.

Going in the right direction.

I don't see "dubious value footchange" wanting me to change MY mind.
Never rode any ov me Harleys with stick between me legs.

This is phase ONE of what we are thinking through.

Please reply Morrag. We welcome your criticism, as it hones down the conceptualisation.
I just can't tie up with the reference points you are citing.

Cos I am making the trike I WANT, first and foremost.

The first thought in my mind was

"That ****ing stick!"

It throws out the balance of what I want to build.
It's ergodynamically part of a fri**in car.

As I said. You can stick your stick (where the sun don't shine)

[morrag]

Mmmmmmm,appears I have struck a raw nerve,sorry about that......oh, the bike flying around the IoM probably had a Guzzi single attached to that Guzzi gearbox...ho hum....

[The pointy helmet]

 
No, not at all!

I welcome any constructive criticism if it can lead anywhere positive.

The ex had a Reliant trike in 1993. I wouldn't piss on it if it was on fire.
But now I'm deciding to have a go at knocking something up.
We have billions of trikes in Thailand and the kids really love em.

What We are pushing is, and pardon my expanse of ignorance, is a "biked" Reliant gearbox.

There may be a number out there.
I feel sure Chris Ireland could fashion something out of a draw of cutlery, that would fit the bill.
but
This is the product of two MM members getting their arses into gear and Drawing, emailing, surfing,
costing, revising, drawing........

The end result could be of GREAT benefit to disabled triker/bikers.
It provides a good DESIGN OPTION for those chopping a Reliant.

It is hardly a new or original idea.
We never claimed it as our own.

We are developing it as a current and reasonably cost effective OPTION.

The Voyager used a soddin great lump of aluminium as it was part of the constructional strength of the machine.

We are offering (one day) a fillet that sits 'tween engine and box.

Already Doc and myself are firing off at different tangents on this.

The GuzzPig is the first look at where this can go.

It is the FZ142.



Doc is legally allowed to use the registered drawings of the Voyager box.
It seemed, and still seems, a healthy option in a marketplace
that is not knee deep in motorcycle shift Reliant boxes.

[Manky Monkey]

I actually quite like jockey shifts, (hand gear changes). Changing gear is all part of the experience of riding a trike -I like having to put a little effort & thought into riding -it's what makes it fun for me. It also means one less lever on the bars. I can see how a lot of people, particularly those used to riding bikes, might prefer a foot change though. Shifting up & down through a bike type ratchet box would be faster than going through an H gate with a stick, but then I'm not personally into racing that much.
If you can fit a Guzzi box, that then opens up the possibility of fitting an auto box, which would be of great benefit to disabled riders, but even the manual bike box could work with the "Klicktronic" power assisted bike gear change developed by the National Association of Bikers with a Disability. So although it may not be to your taste, this could help a lot of people get on the road on 3 wheels who might otherwise not do so, as well as simply widening the range of design possibilities.
How about a Ural gearbox? That'd give you a Reliant with a bike style gear change & a kickstart!
