Just put a fresh top/bottom end in my 08. At about the 1hr mark (3rd moto of the day) it locked up while entering a corner. I knew it didn't stall as it came to an abrubt stop. Kick start wouldn't move. Last night I pulled the right side cover to get a ratchet on the crank primary gear bolt. It was locked up but broke free and rolls over now. I'm guessing I seized the big end rod bearing; I'm just curious as to why at 1hr after a rebuild. Some things I checked: Cam timing was right on Engine oil was drained through a auto paint strainer - Nothing in there Oil filter had no trash in it Plug color appeared to be gray/ashy Any ideas or thoughts?
