Cracked H2 Head

On stock H2 s the heads crack after a while if you use max HP a lot.
On tuned H2 they will crack a lot quicker.
The H2 is the only triple with this problem. Have never seen a head crack on a S or H1-model.

A thick weld on the inner side of the two outer heads (those are the ones that crack) will prevent them cracking.
Be sure to TIG-weld the heads and not MIG-weld them. When MIG-welded, they will still develop a crack.
