I have contacted la sleeves but they didn't respond now for nearly 2 days.

I am now thinking about casting and machining a zylinder myself with a thiner sleeve that is easier to get.

I was going to use the aprilia rsa port designe. There a a hole lot of people making great power with that port design like alex degenes with his old rotary valve spx producing 23hp at the crank and even his new engine with his home cast zylinder is using the rsa port designe.

The problem is that the stud pattern is way to tight on the engime to fit a rsa port designe (45mm square) i could widen it to 50 mm like the miniarelli am6 for which there a great zylinder like the bidalot rf50 wr. But I have done some work in fusion 360 and tge traditional rsa port design doesn't fit in the 50 by 50mm.

So the bidalot rf50 wr for the am6 must have a somewhat changed port layout. But i haven't found specific port angel and position numbers if anyone knows them please tell me.
