How do you set points for a 1974 yamaha 500 - 1974 Yamaha DT 360

walmart has the for 2.69

.018"-.022" if memory serves. If you have a dwell meter to dial it in once you get it running 18 -20 will get you started

gain access to the points, behind the side engine case. once you can see them, turn over the engine slowly, till you see the points at there biggest gap, top dead center. loosen the one screw that lets the points pivot, and adjust to the correct gap, about 14 thou, or a cardboard buisness card is the correct thickness also

Hi Cowboyx16The timing on your DT250 is 1.0 mm before top dead center.
That means you will need a dial indicator to insert in the spark plug hole to measure the piston travel.
You will also need a buzz box or a test light to know when the points break.
Set the gap on the points @ 0.016" then adjust the backing plate up or down to get the points to open when the piston hits 1.0 mm before TDC.


I hope this what you were looking for
