20MM Carb

The Mikuni "VM" Series of Round Slide carbs are the most popular high performance carbs in the sport of motorcycling.

The VM Series has proven to be the performance standard for use in any single cylinder motorcycle. The VM features increased fuel mixture; flow to match engine modifications with precise fuel mixture metering in any application, at any throttle setting, under any riding condition.

Our carburetor specialist technicians have tested and pre-jetted this carb application for your YSR enjoyment.

20MM Carb Kit

20mm round slide Mikuni Carb, Aluminum Intake Manifold, gaskets, Spacer, K & N Air Filter, Air Filter Oil, and replacement throttle cable.

This carb setup is ideal for street riding, particularly if you want to retain the oil injector.

The Kit is a bolt on and go type of modification. Better mid-range and top end performance than the stock set up.This also works good on the track, as the injector can be eliminated easily.

24MM Flatslide Carb Kit

The Mikuni "TM" series of flat slide carburetor provides significant improvement over older round slide carbs, with air flowing faster and smoother through the TM venturi due to the flat slide configuration and the jet blocks which help create a smooth bore effect.

The extemely high velocity of the air flow means a much stronger vacuum at the needle jet, which provides more precise metering and better throttle response.

Our carburetor specialist technicians have tested and pre-jetted this carburetor application for your YSR enjoyment.

24MM Carb

The 24mm Carb Kit is a great modification.

The Kit contains a 24mm Flat Slide Mikuni Carb, Intake Manifold, gaskets, K & N Air Filter, Air Filter Oil, special throttle cable and 1/4 turn throttle.

To use this kit the oil injector MUST be eliminated! (We also carry an oil pump block off plate part #60-6140)

Eliminating the pump obligates you to use pre-mixed fuel. This may or may not be something you want to do if street riding, although it is not as big a hassle as it sounds.

The benefits of making this modification are: increased mid-range power and increased top end power. The flat slide carb is so efficient it carburates very crisp and clean.
