Both engines were in excellent condition.

I never had this happen to me in three years time.

The only fundamental thing I changed was that i ran the Sirio 2013 exhaust on both engines. Normally I run the Novarossi 2052 exhaust all the time.

Do you think the exhaust can cause such breakage ? Because two engines in a couple hours time is a bit far from bad luck.

Or do you know of other reasons why a liner would break in half ?

Best regards
I broke two cylinder liners on a 35 plus 21 over a 4 race period. I have no idea why they broke.
