R1 Gear change
Could someone quickly confirm which direction the gearchange of a 1999 R1 engine goes?
When mounted in a car and if you where sitting in the car is clockwise on the gearbox output shaft for downshift and vice versa for up?
Cheers,
Oli

Hi Oli
The picture on this page (3/4 way down) would suggest that
anti-clockwise is up the gears. This assumes that Im right in saying that a race shift layout is one up, 5 down, but I wouldnt rely on this as they
might even have changed something inside the box to reverse it, rather than mod the linkage.

It is 1 down 5 up I think. The linkeage length is how u change it.
So - looking at the shaft, anti-clockwise is first from neutral.

Yep but is race shifting not t'other way round, so they can upshift whilst canted right over in a left hand corner (its very tricky to lift your
toe upwards to change up on a road bike when leaning right over Ive been told)

Yes but you make a race shift by extending the linkage - nothing more so the shaft shift pattern stays the same.
And yes a race pattern is MUCH easier in a corner!!!

That doesnt make sense (in my head anyway  ) - if the road bike is 1 down 5 up, the linkage needs to be reversed at some point in order to make it
into a race pattern of 1 up 5 down doesnt it? The pic I was posting about said it had a race shift pattern which would lead me to think that pressing
down on the pedal would turn the shifter arm anti-clockwise - shifting up the box?

the actual shaft does the same movement but by lengthening the linkeage you change the way the pedal goes (some bikes need a whole new linkeage unit)
but the key is - the linkage is changed NOT the gearbox.

On a standard the 'pole' would go to in front of the footlever pivot point and be shorter.

The actual lever in the car I would setup as Soopy says

You could aways put the lever on, put it in neutral (light will come on) and then shift the lever.

Thats the bit you didnt say about in the first post which was confusing me, cos just by "extending the linkage" doesnt change it around,
you need to change the pivot point or put the linkage on the other side of the pivot 
So, after all that, the above pic shows a race shift of one up 5 down (am I correct, Im still not sure? ) - if so then to answer Oli's
question, clockwise movement of the selector shaft changes down, anticlock changes up on a stock bike?
As to the shift on the car - do you guys really like push to shift up? Feels totally alien to me, as you accelerate everything is pulled back by
g-force so pulling back feels natural, and likewise changing down your body shifts forward under g forces, so pushing the lever feels right. No right
or wrong way tho, just remind me never to let you lot have a go in my car if we're using the opposite direction!

Good point on the lever direction - may do that myself as it seems common sense!

This is a picture from the workshop manual...
 
R1 gearchange
If you push on the lever to get the bike into 1st the rod will be pushed to the left and the shaft will be rotated clockwise.

Mark

i'm with you on this one Chris, braking hard into corners i would find it impossible to pull back on the lever, i jumped in a Stuart Taylor BEC
that was other way round, i got back out pretty quick before i crunched the box too bits.
If it aint been soted yet, surley you just need to find nutrual, then see wich way it changes gear more than once, thats got too be "up"
the box, or am i missing the point......

The majority seem to side with us, but as Jon said, ST put them the other way as do a couple of other smaller manufacturers. That probably sways
people's decision when setting their own cars up, and once you've tried one way its probably hard to change.

As a slight aside... where would I get a shifter thing that clamps on to the selector splines? I've just paid 7.50 for a sprocket lock nut and
washer so I'm not that keen on asking mr yamaha again. Are there any breakers that anyone could recommend?
Thanks,
Mark

They all seem to use the same spline from what I've seen. I found an old one lying round at the local bike shop. He said I could have it as they
didn't know what it was off. It fitted My ZX9R spline.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

yes chris ,you are right,racers change the pivit or gear change layout out so that pressing down on the gear lever(the one by the foot) to go up the
box.
On R1 turn the gear selector shaft anticlockwise to go up the box
