Scootertronics does carry and install many types of velocity stacks. These can be installed on GY6 CVK carbs from 50cc to 150cc as well as the 250cc CN250 engine and Linhai engines.

A Velocity stack will work best when adding big bore kits as well as exhaust and carb upgrades.

These will not work well on stock set-ups. UNI Dual Layer Air Filters work best on stock engines.

These are used on the SRC scooters that we race with on OKO 21mm-28mm PWK carbs as wellas the Mikuni TM24.

The 250 CN250 Engine found in a lot of scooters these work well on stock engines.

All Velocity Stacks have screen to keep dirt and trash out. The use of velocity stack should be considered during other mods. Stock engines should use UNI filters.

All high performance air filters take the place of stoc air box.
