언더본엔진 밸브소음, 시동불량, 타이밍포인트 밸브조정하는 방법 To Adjust The Valve By Setting The Point Timing [바이크브로 중급자 DIY]

How to Adjust Intake and Exhaust Valves on an Underbone Engine Rotary Gear Motorcycle (Knowing how to set the timing points on an underbone engine is essential for accurate valve adjustment.) Applies to underbone engines such as the City 100, City Ace, DD 110, Super Cub, Doris, and MSX 1. Brief explanation of the engine and rotary gear system of the Honda Underbone Doris 125. 2. Tools for adjusting the underbone engine head valves. (An 8x9 megane for valve adjustment and two tab adjustment bolts are essential.) 3. When setting the timing points, always rotate in the direction of the engine rotation! (The timing mark T must be aligned correctly for valve adjustment!) 4. We'll explain how to set the timing points. This is also essential for engine disassembly and assembly! 5. We'll explain the intake and exhaust valves. 6. We'll explain how to set the intake and exhaust valves. (Starting the engine is much easier if the exhaust is slightly open than the intake.) 7. All service manuals contain valve settings. (Experience is important, but working with accurate data is even more important!) 8. Double-check the settings with a valve gauge. 9. After setting the valves, run the engine 2-3 times and recheck the valve settings. (If the valve settings are incorrect when rechecked, the valve is faulty and needs to be repaired.) 10. Always use hand tools for engine repairs and valve work. (Using incorrect tools can cause damage to parts.) 11. When reassembling the valve cap, clean it with a cleaner before reassembling. 12. Start the engine and check for valve noise and whether the engine starts smoothly. 13. If the noise reoccurs, repeat the same procedure to further reduce the valve settings.
