clutch pedal or not
just wondering if anyone has mounted their clutch lever onto the gear lever, and if so, how you got on with it? Im thinking it would be perfect for
footwell space and left foot braking. cheers.

Not a bad idea but wouldn't it make for a slower change aka old mod scooters??

I'm not sure I'd go for it....
I tend to quickly grab the stick, shift it and get back to holding on for grim death.... Having to hold on to the gearstick for long enough to feather
the clutch might be a pain.... You'ld probably also have to have quite a longish gearstick (other the clutch level will be so short it will be
viscious (BEC clutches can be a bit like that anyway) which might slow down shifts...
Then again, it might work if you get the hang of clutchless shifts.... I'm still too chicken to do it!!!!

I can see there being an advantage or two, as the clutch was originally hand operated, so you could still use the orignal stuff, and have the clutch
working as it was intended. As for changing gear, it doesn't take that long, although getting two hands back on the whell may take a moment or
two longer than desired, compared to just banging the lever quickly.

my reasoning is basically the car will only get used on track, so up the box will be clutchless (got the hang of it in my last motor) and down is a
matter of bang bang bang into the corners. It will be easier to raise the revs. Also, i dont like paddle shifts, i dont think the position lends
itself to clutchless changes, i find the arm motion nice when its over the tunnel. I also dont like the gearlever to change angle much as i pull it,
so i will pivot it at the bottom of the tunnel. The gear lever will be tubular and rose jointed, and in an 'h' shape over the prop shaft
to double as containment in the event of prop failure. So this set up lends itself ideally to locating the clutch there. However, as some of you point
out it might be awkward to disengage before hammering on the lever. Will definately take some getting use to! Its not my idea though, im sure ive
heard of someone else doing it, hence i thought id ask!
The reason i ask today is that the mounts for the gear shifter link up to the seat mounts, and its all getting cut today!

I know you've said you don't like paddle shifts.. but would it be any use putting the clutch on a steering wheel paddle so it could be
operated by your right hand whilst still steering?

i may be wrong but i think that would leave no hands for steering (gears in left and clutch in right)

Not locost, but I am going to use a trickshifter with my R1 engine. You only need the clutch to pull away, plus less risk of damage to the gearbox
etc.

Hi J,
I saw one in a kitcar mag time ago - they had used the bike clutch lever on the shifter which was just a piece of round section.
Aparantly worked really well.
All a matter of co-ordination I guess.

Noo! ment a like a gear change paddle that you would operate with your fingers whilst sstill holding the wheel!

clutch lever can work well, but better off using a paddle on the steering wheel

I am also considering this. However, I think I have to do upshifts forward and downshifts rearward. If the clutch handle is in front of the gear lever
it could be easier be used for downshifting...

What about mounting the bike clutch lever in the bottom of the tunnel, facing upwards? Extend the gear lever down through the pivot point, past the
push pull cable for the gear change to a roller bearing at the bottom. This bearing would act on a U shaped bit of ally transfering the fore / aft
movement of the gear lever into an up down movement of the clutch lever. That way it would put the clutch in if you pushed the gear lever forwards or
backwards? Sitting in traffic, just keep the lever pushed forwards?
By carefull working out the ratio you'd only get the clutch in for when you needed it, ie exactly when changing gear.
Perhaps I'll sketch it out tonight, or I might go and have a lie down!
Cheers
Mike

not a bad idea that mike, cunning use of springs to ensure it only operates one way, would still work for neutral to first too!
Have the gear shifter as a V at the bottom of tunnel, with the bit you press leaning against the back leg and the clutch lever squeezed in against the
front leg, pushing forwards first squeezes clutch open then changes gear when pressed further, fast gear changes you could just click it through the
final part of the movement. Clutchless gear changes compulsory going up the box! Would be difficult getting it into neutral again though
