Once again, I must plead ignorant as charged. I don't know what you mean by pre-fire. 790, 270, 360 are terms I understand when used in the context of displacement and ignition. But prefire, I don't understand what you mean.  Must have something to do with ignition but a duh... I don't know what duh that means duh..... 
that was big ignition  pre fire means made before old Triumph factory burnt in 2002
