Actual Displacement = 491.05cc

Notes: This is a budget friendly engine build.  While it is quite reliable it really is only recommended for trail/play riding.  The cylinder skirts are the weak point with the short rod stroker crank.  They hold up pretty good but are not the best choice for someone that races their equipment.  We would much rather see you use a lined cylinder.
