Thanks again for your tips,
I did it again but this time after the intake (in/out) movement. Then move the cylinder up, adjust valve with the 1/6 trick. The bike make some little back fire and stall at high rpm and didn't reatch the third gear.
I didn't see Taffy's recommandation. I notice à white line+ the edge on the ''generator'' flywheel.
If intake valve (in/out) is done, cylinder completely up, what would be the next step?
Should I use a 0.12mm ''shim'' to adjust the valve? If yes, can I use 0.13mm? I may have to bend it.
Thanks!
