Replacing kick start mechanism on Baotian Comfort Scooter GY6

Strange noise from engine when idle and rev the engine...
Includes change of bushing, kick pinion and kick sprocket. In this video I'm troubleshooting my Chinese scooter. Needs new bushing and washer and I replace kick start assembly sprockets.
Checking and try to find the problem with strange noise / sound from the variator side. Scooter is an Baotian Comfort from year 2014. See my other videos when I acquire it and fix it. Series is availble.
Video inclue Starter Lever / Kick start and Idler Gear. Also spring for kickstart shaft, the same style as GY6 49cc or 50cc. Lifan Scooter I believe is the same, also Moped 139QMB and 139QMB.
Compatible with P139QMB engine, 4-stroke.
