Front wheels hopping/shaking at high speeds

I noticed on the street when I’m at higher speeds 30mph and up it seems my front 2 wheels wobble and hop a little kind of shaky. It is felt thru the handle bars. I’m not sure if it’s out of alignment but it’s nothing like a vehicle smooth on road which I don’t expect that especially with the mud tires but was wondering if something is probably off toe in or alignment maybe

That could be. Could be wheel balance also. These no not have super refined steering systems to start with. If you do not run a steering stabilizer, a little twitching is not out of the ordinary. I would check the alignment and check for a bent wheel.

Oem front end geometry needs more castor, it is not very stable at speed and definitely not meant for on-road use. You can lower/widen the front to help or add a steering stabilizer. Fireball racing front ends have more castor and handle much better at speed.

Okay I will check to make sure everything looks to be in spec and I also do have plans on the future to maybe widen stance just a tad bit, this thing feels very top heavy and I’m only 130lbs

You can add caster buy moving the lower a-arms forward or move the top a-arms rearward. Trimming the a-arm bushings slightly will allow the placement of washers to move them.
