First, my re-sleeved cylinder can't do competitions, because the sleeve, not allowed. So i have to build another 12hp+ engine. I still can use my resleeved engine for traning days.
So, for the new engine, a fresh milled pair of reed cases.
New cylinder will be ready in a few weeks.
Better disc brake, Galfer 260mm, 4 piston caliper. Have to make a custom adapter to fit the caliper.
