Frequently Asked Questions
Are Replacement Throttle Balls Sold Individually or Only in This Kit?
Small selection sells solely as a kit. Swiftly stacked shades: assorted sizes sprinkled. The answer: replacement options are packaged together, not offered individually, so users choose from included throttle ball sizes within the Holley 20-2 assortment kit.
Can These Throttle Balls Be Used on Motorcycles or Small Engines?
They may fit some motorcycles and small engines if throttle bore and linkage dimensions match; compatibility depends on application. Motorcycle compatibility and small engine performance should be verified by measuring bores, linkage geometry, and material suitability before use.
Do the Throttle Balls Require Lubrication Before Installation?
Right off the bat, yes: a light coating helps. He recommends proper lubrication methods — thin oil or assembly grease sparingly — and follows installation tips like full range movement checks and avoiding over-lubrication that attracts grime.
Are There Color or Finish Options for Aesthetic Matching?
No — the kit offers no color options or finish alternatives; it includes the standard zinc plastic throttle balls only. The reviewer notes appearance is functional rather than customizable for aesthetic matching purposes.
Is There a Recommended Storage Method to Prevent Corrosion?
Yes. Store components dry in a sealed container with silica gel; apply light oil or corrosion inhibitors to metal parts; use foam padding to prevent scratches; label and rotate inventory periodically to guarantee preventative measures remain effective.
