Been looking for a Z for a while now. This one was the best I've seen in the area. Needs a complete tune up tho. The owner said he was getting out and didn't do it at the end of the season. He has a bunch of stuff for sale. Quick question. How much oil does it take for the hydro? I'm going to order a filter and drain the system but not sure how much Mobil 1 to get also any one know where the best place to get new front tires at a good price? I might go with the foam filled.
