How do you set the timing on 1984 Honda 250r 4 stoke?

Answer 1

There is no such thing as a 250R 4-stroke!!! They are all 2-strokes. yes there is xr250r or cb250r there should be two holes on left side of engine one big in the middle and one small just above it the small has the timing marks in it spin the motor over till it is on comp stroke top dead center look though the small hole to see your timing marks there will be two t and f i think from memory you line it up with the f mark if its out you need to slip the timing chain a tooth or two on the cam so you need to take rocker covers off to do that and loosen timing chain tensioner
