Valve adjustment time. This is done dead cold or after parked 8 hours
Remove the plugs, shifter lever and left engine case cover. Grab the rotor and turn CCW till the cast pointer at the top of the case is pointing at the T mark. One cylinder's valves will have some play, those are the ones you're adjusting. Intake = .004" Exhaust = .006"
Loosen the adjuster nuts, insert the correct feeler blade between the adjuster and top of valve. Using 2 fingers, 2 not 3 or 4, on the screwdriver tighten the screw until it stops turning, now snug the lock nut down. The feeler blade should slide in and out with a slight drag/resistance. Slides easy/no drag felt or it pull out but won't go in? Readjust until it's right and move on to the next valve. Once the first side is done turn the rotor again 1 full turn to the T mark and repeat on the other side.
