Gear Linkage Pivot
Hi,
Trying to think of an easy neat solution to connect the pushrod from my paddle shift to the pushrod connected to the gear lever selector on the
bike.
Best example I can find and closest to what I am looking for is from Ox's photo archive.
Anyone any ideas or suggestions?
Cheers,
Pat....jpg)

Just thought though, if I could buy a steel gear arm, I could do it like this:

Can you buy steel gear lever selectors separately so I can extend it and have the pushrod vertical?

If I could get the thing vertical, it could pivot easily on the shoulder of a bolt between two brackets.

Hi Ox,
That's the aprillia bit is it?
Does it just pivot on a bolt?
If I can extend the gear lever selector (by hopefully buying a steel one) I can do it like that.
Cheers,
Pat...

What about welding an extension arm onto your selector lever?

What selector lever have you got at the mo' Pat?
There were two types fitted to the early blades.
893cc use a simple alloy lever which is approx 5" long. Could you not drill out the toe peg and replace with a rose joint?
919cc blades use a 'rear set' type linkage (as the gearbox runs in the opposite direction to the 893cc) with a short stubby selector.
(I'm not sure if this is alloy or mild steel but it seems heavier than the alloy one, so may be able to extend it?)
I've got it fitted to my engine, so if I get chance, I'll nip out to see if its magnetic or not!
Andy.

Where can you buy ball joints or pivots like those on your pictures OX and Pat? How much?
Ta,
Chris.

My arm isn't long enough and is a small alloy item with a kink in it. I could extend it, but I can't weld alloy!
It just needs a straight piece of flat bar to extend it.
I'll get a pic shorlty, but F1 is about to start.

Chris - I can do those ball joints for you, just need to know how big. They come with ball & socket.
Best Regards,
Steve.

This is the older blade one - might do the job.
Can you weld alloy?

So is that one still not long enough, then, Pat? (That's the one I thought you may be able to drill out the rubber covered peg and replace with
a ball or rose joint.)

Dunno...not too hot on welding techniques..Others to answer that one!
However, I've got the same gear lever in the garage somewhere.
I'll find it tomorrow and measure it.
Do you know what length you actually need?
(I bought both types of lever on ebay (do a search for 'fireblade'
Expect to pay about a tenner each inc. postage.
Andy.

Hi Andy,
This makes a change me asking for advice!
I've just won one of the longer ones on ebay for £4.99 so will compare the two when it lands and then work out what to do.
Just go to work out the top pivot/arm now and how best to make it slip/twist.

Right, after a waffle with Ox (cheers), I'm now looking at something like this which looks ideal for the top mount and would be dead easy to
mount with two lugs and a bolt through the lot.

Obviously I'd loose the two rose joints, small bar between them and the splined gear lever bit.

The lever I used for my lower link was a steel one I picked up from a breaker.
It started life about 6" long, bendable and weldable to shape, see pic here (just)

The honest answer is no, but I would guess a small Honda 125 type thing, though i'm sure there are many bikes with the same spline
