Stock SX 250 2024 cylinder base gasket?

insertinfo

Hey,

Doing my first top end, it’s a 2024 MC 250, old gasket is 0,53/0,51/0,55 depending on where i measure it, i can do 30+25 so 55 or 40+20 that is 0,60…

Can’t find anything on the repair manual.

Thanks in advance.

You want X dimension set level with top of cylinder bore. You tube ktm X dimension…piston should be level with top of cylinder bore…using a straight edge across top of cylinder…the base gasket stack sets the dimension…
