(E3) Hellcat Raptor dirt tire install, BAD vibration super easy fix. Honda Grom VS Clone race!

Bought nobbie dirt tiires and installed, they work great! Developed a bad vibration from the engine when revving, even shook the footpegs so bad it hurt my feet! The repair was so simple I missed it and checked the timing chain slack, exhaust leaks, pulled off both side covers looking for anything! Then I saw it, hidden in plain sight....
My Samsung Galaxy actually focused properly this time on full zoom! Yay

It goes pretty good for a 125cc bike (55 mph after tune), suspension is nice, braking is good. 0-50 mph in 19 seconds

Frame bolts: The ones on a bike or metric but 5/16-18 or 24 (preferred) 5" long will work. I'd get grade 8, Grade 5 minimum. (https://ebay.to/2zdtG8a Grade 8) (https://ebay.to/2L5sCWq Grade 5)
