i bought my project for 500 bucks. but it was a complete bike beat to hell and back.
i did top end rebuild, clutch, all new bushings bearings, pipes, chain, sprocket. basically everything needed replaced but it was a completely bone stock banshee.
i already have about 2500 total invested into the bike, but its built the way i want it to be.
just saying some projects you really need to think about what all you need and what its going to cost you.
IMO i would just buy a bike that needs a fresh top end for around 1000-1500 dollar range and start from there
