Re: Predator 670cc V Twin bike
Get the frame and engine, and I'll be happy to help you find the other stuff to fit it. Basically you will need wheels with brakes and axles, swingarm with bearings and bolt, forks with triple tree and a handlebar. And a gas tank. You can get a new plastic tank intended for a KTM 50 for about $35.
All the used parts I just listed are very readily available, so you don't have to buy everything at once.
