Hi Guys, I’ve recently purchased my first banshee after wanting one for years. It’s road legal but it handles terrible it shakes like crazy at high speeds, I have to hold the handlebars about 25 degrees to the right to drive straight, sometimes the bike just pulls itself to one side whilst I’m just driving straight. Something is just not right with it and I would love some advice as I’m a complete beginner lol! the person I bought it off had it powder coated and fully rebuilt it (I think by himself) he said he’s replaced every bearing and bolt, +2+1 A Arms wheel spacers probably about 45/50mm renthal bars If anyone has any advice on how to fix these problems I would highly appreciate it if not I will have to take it to a professional but I’m worried how much they will charge me.
