And just a friendly peace of advice. If and when you split the case be careful cuz the top case has I think 4 little pins that hang down to hold the bearings in place so they won't spin while the motor is running. And when you put the motor back together lay out 2 blocks of wood and take the top case and lay it upside-down on the 2 blocks of wood "making sure the little pins are in place" and lay the crank in the top case and making sure the BEARINGS LINE UP or FALL INTO PLACE by moving the bearings around till they lock into place. Then the bottom case can lay on top of that while still upside-down. I learned the hard way so I want you to know.
RIDE IT LIKE YOU STOLE IT...!!!
