Carburetors (carburetion, carbs, carburettors) jet kits for motorbikes (made by Dynojet - USA)

Dynojet carburettor kits increase your engine's power and acceleration.

The difference in performance is due to the patented Dynojet fuel needle, which thanks to its sharper shape and provision for adjustment generates better fuel flow to the engine.
The first thing you'll notice after installing a Dynojet kit is that your engine revs up must faster than before.

Kits contain graduated fuel needles, different series of jets, washers, cotter pins, springs and drill bits for cases where the hole on the slide assembly must be enlarged.
The kits indicated thus (**) also include needle jet cap nozzles.
Depending on the needs served by each kit, fuel needles may be aluminium, titanium or steel.
Clear instructions (Italian and English) are included in all packing for easy setting.

Dynojet carburettor kits are available in 2 stages.

Stage 1
To be used with the stock engine and air-box.
Designed with different calibrations (all included in the kit) for stock air filters, K&N air filters, stock pipe, stock manifolds with racing mufflers or complete racing exhaust system.
Power increase is approximately 5%.

Stage 2
To be used with a modified air-box and a stock or mildly tuned engine.
Designed with different calibrations (all included in the kit) for stock manifolds and racing mufflers, complete racing exhaust systems, stock air filters or K&N air filters.
Stage 2 kits are designed for applications where individual filters cannot be installed and for applications where air-box modification improves the engine's performance.
Power increase is approximately 8%.

For higher efficiency, we recommend that Dynojet carburettor kits be installed with the associated K&N / air filters.
