I am looking for some advice on my go kart that I would alike to part ways with. It is a late 90’s (that really doesn’t seem like it was almost 30 years ago) Comet Mach 1 EXP dual engine frame. It is clean and straight and was only races a few times when it was new. It comes with a Briggs Raptor 1. Can anyone help me identify what it’s worth and where a good place to post it for sale would be? Thank you for your help.
