well guys this fall i want to rebuild my motor. Its a tak. 106 old style super head. I want to replace the piston, rings, gaskets, check valves and go through the motor. The bike runs awesome with no smoke but it will make me feel better to get it done. So where can i get a rebuild kit for this motor. If they don't sell one then i might to to a tb117 bore but do i need a new crank. Also what should the intake and exhaust valves be set at? Please help
