Essential for any motorcycle/scooter workshop, this BIHR jet box brings together a selection of jets designed for PHVA/PHBN carburetors. Ideal for carburetion adjustments in urban settings, it allows for fine-tuning of fuel flow during maintenance or preparation operations, from idle to full throttle.
Designed to replace or complement the original jets, these jets facilitate the adjustment of the air/fuel mixture and integrate with work on the needle, float, and mixture screw. They are suitable for urban applications and are commonly used in 50 cc scooters equipped with PHVA/PHBN carburetors — for example: Vent Derapage 50 RR, Honda Camino, Vent Derapage 50. Check your carburetor reference before intervention to select the appropriate flow rate.
Practical in the workshop, robust, and easy to handle, these jets form a basic kit for carburetion preparations and diagnostics on scooters and small-displacement motorcycles.
