Expert Pro-Tip: A total engine rebuild requires absolute cleanliness and attention to detail. When splitting your CR250R crankcases, never use a screwdriver or pry bar to force them apart—always use a proper crankcase splitter tool to prevent damaging the mating surfaces. Additionally, ensure you freeze your new main bearings and gently heat the case houses prior to installation; this thermal expansion trick lets the bearings drop into place smoothly without galling the aluminum journals.
