My buddy and I bought this in hopes of making a Paramotor. He ended up getting a great deal on a ready to fly package. So, we are looking to get rid of the engine and pipe. We have the receipts from comet kart where we bought it from if you want to see them. We paid $750 plus shipping for the engine and $172 plus shipping on the pipe from TNR We will take $800 for both and we will cover the shipping. These items are brand new and never touched! Bought 4-5 months ago. Email me at firstname.lastname@example.org. First one with PayPal gets them.
