Frequently Asked Questions
Q: Is this a complete top and bottom end rebuild kit?
A: Yes. This is a comprehensive kit that includes the crankshaft, piston assembly, main bearings, transmission bearings, water pump bearings, oil seals, and a full gasket set for a total engine refresh.
Q: Are these components matching OEM dimensions?
A: Yes, every component is engineered to standard stock dimensions and meets or exceeds OEM specifications for performance, structural tolerances, and long-term durability.
Q: Do I need to buy anything extra for a standard case split rebuild?
A: This box includes almost everything needed for a standard overhaul. However, always inspect your transmission gears, shift forks, and oil pump components during disassembly to check if separate replacement parts are necessary.
Expert Pro-Tip: When splitting the cases and replacing your entire bottom end, never use a hammer or a pry bar to separate the case halves or pull the new crank into place. Doing so can easily tweak the flywheels out of true or nick the sealing surfaces, destroying your new parts before they ever run. Always use a proper crankcase splitter and a crankshaft installation tool. Also, don't forget to clean out the internal oil passages thoroughly and apply a high-quality 2-stroke assembly lube to the new bearings during the build process to guarantee a smooth first start.
