you guys probably know all this, but in case another fool like me looks in with problems
try this and the engine runs so sweet and starts 1st kick
30 degrees BTDC INLET
25 degrees ATDC EXHAUST VALVE FULLY CLOSE
POINTS START OPENING ON FULL ADVANCE
1/2" BTDC on compression stroke.......... yes 1/2 inch.....not 7/16"
BIKE RUNS COOL AND SMOOTH AND IS FULLY RESPONSIVE TO THE ADVANCE/RETARD LEVER
