Any motor should mount up. Some may have issues with the front tire hitting the head. I personally would choose the 88 bore kit. It's reliable, can make more power, and parts are easy to find and cheap. Reliability is close to that of the stock Honda if you get the TB kits. See link at bottom for what you need. I bought KT-903 tires for my Z. They are not slicks but a mild scooter tire. I am very satisfied with them.
