Bon, en attendant qu'une production spécifique LCBC se mette en place.
Dans l'esprit du partage des infos quand on les cherche et les trouve... Tout le monde connait "ET" ... l'animal d' la piste a trouvé une filière... le sujet a été.. est traité depuis des lustres par les courseux.. Kedo a produit aussi des choses... juste une question de "sous" selon certains... ha ha ha ...
Je ne dis pas que ce qui est en dessous est la solution pour le LCBC.. non... je dis juste que les choses peuvent être faites selon des pratiques déjà en cours... comme ci-dessous :

Hello from France
My racing XT/SR 500 began to be fast and the engine has a pretty high rev power.
As my winter project is to fit a modified 500 SR frame with clip ons, I think to the next major evolution ... I still have the genuine 33% first gear and I want to fit a close ratio gearbox.
Kedo were selling a close ratio gearbox by the past at an unaffordable price.
I am sure that we could fit some gears from recent Yam dirt engine, but wich ones, anybody have any ideas ?
No friend want to let me his YZF engine just to open

brgds

Hi,
I have done a close ratio gearbox for my SR racer this winter, and its in my engine already. Will be testing this Saturday Feb 26th. All gears but 4th re designed and newly fabricated. Taller 1st and shorter 5th. Will post ratios and pic later.
Let me know if you are interested. Price around 1000 Euros plus shipment. Based in UK
Cheers
Hans

Folks
I have done nearly a season now with my close ratio gearbox. Just to say it works phantastic. Starting is easy now you just give it the stick when the lights go out. With the standard box you had to be very careful about unwanted wheelies. Now the 1st is useable for hairpins, and downshifting in any gear is not causing blocking rear wheels any more because of the smaller revs gaps between gears.
I am going faster on each racetrack with more or less the same bike as in the previous season.
Cheers
Hans
