Good news all I got the kart back from Joe ! Spent Sunday accesing the final details to finish the build. I had to purchase a 2' length of 1-3/8 thinwall tubing to connect Joe's pipe to my silencer. Wrapped up a few odds and ends last night such as coolant, trans oil, and the clutch cable. It was a real chore trying to get all the coolant into the system, gravity is not the greatest with a kart cooling system. I hope I didn't get the system airbound, we will see I have a coolant temp sensor so i'll know right away.
