long bladed flat head will pop the oem copper gaskets out. use a dab of grease or vaseline on the back of the new ones. that way when you push it into the head, they will stay. if you dont, they will fall out. the grease or vaseline will burn away once they get up to temp.
if you are using brand new gaskets and torque everything correctly, you should not have to use high temp silicone for exhaust leaks.
if you think the yosh is the only system that gives people problems, think again. most full systems are a bigger pain in the ass on this bike versus others.
Being right is bitter-sweet when you're ruled and surrounded by morons.
