Vino 125 very slow at bottom speeds
 

Howdy! I have a 2007 Yamaha vino that hadn't run in about 2 or 3 yrs until today. I finally got around to changing out the shredded old belt, put it back together and started up. She idles like she wants to poop out on me but when I give her gas she wakes up. Then as I get going, even at full throttle, she takes about 30 seconds to get up to 15 mph. Once there she takes off! I had her up to 65 twice today!
Any idea what my next steps should be? Fuel? Clogged carb? Air leak? Clutch? I'm learning still and would love some help.
Thanks!https://uploads.tapatalk-cdn.com/201...c06b999c40.jpg

Oh. Also, she shakes and vibrates like mad until she's up to speed.

Adjust the valves, clean fuel system, 100% gasoline, check the jetting and adjust the carburetor, check for vacuum leaks, good quality spark plug, good battery. Know the limits of your scooter and you should be good to go.

Thanks Roscoe.
