Busa gear change

I hope I have enclosed an image/drawing of the proposed gear change on my Gen 1 Busa engine.
I would like to pull the leaver back to change up, can somebody please have a quick look to see if its ok or will I have to alter the pivot point to get the leaver to work as I need.
Cheers
Phil
PS if the image is not shown I can email if needed..

Looks right to me. Easy way if I remember correctly - its toe down on bike to go down gears and toe up to go up !

I think you have it the wrong way round, when you pull back you will be changing down not up! you will need to move the rod to the engine above the your pivot point so when you pull back you move the gear selector arm up/to the right.
On my Busa the gear selector arm is at 3 o'clock (yours is at 6 o'clock) so you pull the arm up to change up and down to change down.
hope this helps

Yes, that is the wrong way round.

Many thanks, so to change up the leaver on the box has to turn anti-clockwise ?
I can either change the pivot point on the gear leaver or as you said put the leaver on the gearbox at 12 o'clock
Like this ?
Cheers
Phil

You won't be able to do it on the engine end as the engine gets in the way!

I just looked at some pics and can see what you mean, I will make the gear leaver with pivot below the gear rod connection..like in the last drawing.
Thanks again for your help
Phil

Also work out the ratio to see how much travel you need at the lever or make it adjustable , you will be surprised at how short you can make it

Good idea I can make a temp one with different locations for the gear leaver rod then adjust to suit...
