Hello, does anyone know if there is another crankcase that the same as the Protek 321B v2? My case is damaged but I want to still keep the motor.

I think a case from one of these would work. Think it’s same engine besides carb and head. 321b was based off this. 321b has 21j carb. 321bv2 has 22c carb.

I think this should work but I’m not 100%. Better off trying to find a used old engine from someone for a case

Can we use xz-b spec 2 crankcase with v-spec 2 internals? Does anyone know?

Vspecs and 321b are short stroke.
xzb spec 2 is long stroke
my guess is no stuff wouldn’t line up in case
