Does it do this every time it is accelerated? If you keep it at higher rpm does it continue to bog, but also guessing since your limping home may not want to find out right now

Little update running fine when i very slowly accelerate only seems to happen when i get on it, could this be belt slipping??

Don't think so right now with the motor shaking like it was, I'm thinking fuel issue. In most cases a belt would start to squeal

Ok ill check the filter when i get home i just thought it looked like it was slipping in the video
