I bought this moped a month ago, is a Chinese moped 2 stroke with a vertical engine, same as the Yamaha jog, I bought it with a bad carb issue, I bought a brand new carb called 1pz 19mm, I put it on, and my first stroke was that I plugged the fuel line on the wrong input it did started some how but died like a minute later, then I mask usted the float thinking it was the issue, but it wasn’t, now it Boggs every time I hit the throttle like more than 25%, also if I put my hand in the carb covering must of the intake it starts and revs all the way up please somebody help

I'm experiencing a weird whistle/whine noise when giving throttle on my 09 Yamaha YZF R6.

I just did the valve clearances and never heard this noise before, I reconnected everything the same way I took it off and was sure to triple check I got my timing marks lined back up when reinstalling the cams.

Has anyone experienced this/ have any idea what could be causing this? Main concern is I may have skipped a tooth or something on my timing.

Short video of the noise clearly audible when test riding: ​https://youtu.be/3_altVgHdvI?si=La75g-zG...
