Low speed shaking/shuddering (finally got a video)

Was hard to take video to try to capture this but this is the best I could do....hopefully somebody can help me diagnose this shake...

Current set up is stock muffler stock everything...#65 jet and needle clip 2nd position from top...

I was thinking this was a wheel issue but now I'm going back to a performance issue causing the shaking and it mostly felt in front end because it's way closer to the engine and it's lighter up there versus the back...

I'm 200 lbs and top speed I got was 29mph....I believe that was with air filter off and maybe a little down hill....I'd say my average top speed is 26mph
