If you want a simple solution for your 1989-2001 “Prebug” Yamaha zuma / Booster here’s a great solution from Polini. This full kit includes the “Big Valve” performance intake, Polini 21mm CP carb, remote choke cable kit, and air filter. Also included are the 90 degree cable fittings to make an easier fit.  You will need to cut your old oem cable, and slide in the new inner cable. 

You save over $100 with this bundle, as you don’t need a motion pro cable!
