ZachBreck Posted September 15, 2007 Report Posted September 15, 2007 I know I have been asking alot of dumb questions but I am trying to build my bike back right. What does all the number and degree mean on heads, like 71 BORE, 21CC, 12 DEGEE ANGLE, I know CC is the dome size for compression, but what does the bore have to do and the 12 degree angle. I just got my bore .40 over a mile dune port with boyseen and stock cards...would this head work for me? Quote

locogato11283 Posted September 16, 2007 Report Posted September 16, 2007 are you buying an aftermarket head or what? so you just had your cylinders bored to 40 over? if the domes on the head say 71mm bore, then no they will not work for your application. we need some more information. Quote
