Thanks you all for the nice comments.
I'm quite happy of the result. There is a bit more in the engine, but prefer keep it like that and don't push the rev too high as I use simple HD springs.
Lot's of torque for a small cc's, drive like a stocker up to 3000rpm and make some good power until 5000.
This gearbox is a blast on highway, but a bit long on back road. I believe 4th gear is a 0.89. It's not a racer, more a driver, so it's good to me.
To Fabian, really sorry dude, I've been busy all the time last past months with a lot's things to do, and with cold time coming, you know that I will be even more busy
You met my friend Jean-Philippe at DDday and he also said me that I miss you
