Hot off the fax machine from Honda Canada (thank you for your cooperation!) is this chart of revised valve clearances for the V4 bikes. In all cases, intake and exhaust are set to the same clearance. Note that these values are used in conjunction with the special tool! See elsewhere on my home page for that information. MODEL VALVE CLEARANCE IDLE SPEED 1984-85 0.16 mm 1400-1500 rpm VF500C Magna VF500F Interceptor 1985 0.14 mm 1000-1100 rpm VF750C Magna (*) 1982-83 0.15 mm 1200-1300 rpm VF750C Magna VF750S Sabre 1983-84 VF750F Interceptor 1984 0.15 mm 1000-1100 rpm VF1000F Interceptor 1983-85 VF1100C Magna 1984-85 VF1100S Sabre (*) SPECIAL NOTE FOR 1985 VF750C Magna The ring of the special tool should be re-installed so that the notch faces down. The special tool should have the notch in the ring facing up for use on all other models.
