Tried to make a video clearly showing how and where to adjust the valve clearance on a Honda Grom. Hopefully this video helps some of you out there save some time and money. If you have any questions feel free to leave a comment or search the threads on

Valve Clearances should be:
Intake: 0.10mm +/- 0.02mm (0.004 inches +/- 0.001 inch)
Exhaust: 0.17mm +/- 0.02mm (0.007 inches +/- 0.001 inch)

Hey I was attempting to adjust my valves last night and it seemed like I had to back them out WAY to much to fit the feeler gauge in there. I woke up this morning and started my bike and it sounded like it was loose and kinda rattled. Any help would be very much appreciated!
