I have a freshly rebuild engine top and bottom new bearings piston and everything. My question is how cold is too cold to break it in effectively? I live in Michigan and its about 25 degrees right now. Im very impatient and don't wanna wait till spring.
before last spring i had KOR cut my head and port my cylinder and i wanted to bolt it back together and start breaking it in right away and he told me don't do it your gonna wanna go out (i had snow on the ground yet) and do doughnuts and mess around and be sending it right back to him blown up it was worth the wait let the temps get back above 45-50ish
