Hope this helps bud! let me know how it works for ya!
Timing a YTM200(or any Yamaha 3-wheeler according to the damn Haynes manual)
(Two Stroke Motors)
Remove the cover from the left side of the engine. Locate the timing mark on the AC generator rotor and carefully fill it in with white paint to aid visibility when the timing light flashes.
Connect the timing light according to manufacters instructions.
Start the engine and point the timing light at the mark on the engine case. The timing is correct if the rotor mark aligns with the case mark at the specified rpm.
(Four Stroke Motors)
The procedure is the same as for two-stroke engines, but the mark on the rotor is exposed by removing the timing window plug from the upper surface of the left engine case. The "F" mark on the rotor must be aligned with the notch in the window when the engine is running at the specified rpm.
Ignition timing check(rpm)
YT60/175:1600 +/- 50
YT125:2000
All four stroke models: 1400 +/- 50
