Yamaha Banshee 350 Dual 34mm PJ-Type Carburetors – Custom Tuned Pair
Upgrade your Yamaha Banshee with this pair of 34mm PJ-type performance carburetors, custom tuned specifically to provide a strong baseline for modified Yamaha Banshee YFZ350 engines.
This listing includes two custom-tuned 34mm carburetors plus spare tuning jets. No throttle cable or intake manifold is included.
Ideal for Modified & Big-Bore Banshees
The larger 34mm bore provides increased airflow and fuel-delivery capability, making these carburetors an excellent choice for Banshees that have been modified beyond a basic stock setup.
Great for applications including:
- 421cc big-bore/stroker builds
- Other big-bore cylinder kits
- Ported cylinders
- Aftermarket performance exhaust
- Performance reed valves
- High-flow intake systems
- Open airbox or pod-filter setups
- Dune and aggressive trail builds
- Drag and race applications
The 34mm size provides an excellent balance of throttle response, midrange power and increased top-end airflow, making it a versatile carburetor size for many performance Banshee combinations.
Custom Tuned Banshee Baseline
Rather than receiving generic out-of-the-box jetting, this pair is custom jetted and set up with a Banshee-specific starting baseline.
Main jets, pilot jets and needle settings are selected to provide a solid starting point for a performance Banshee application.
Spare Jets Included
Additional main and pilot jets are included for fine tuning your particular engine combination.
Jetting adjustments may be necessary for:
- Engine displacement
- Cylinder porting
- Exhaust changes
- Reed and intake modifications
- Air filter setup
- Fuel type
- Temperature and seasonal changes
- Humidity
- (2) 34mm PJ-Type Performance Carburetors
- Custom Banshee baseline jetting
- Spare main jets
- Spare pilot jets
Throttle cable and intake manifold are NOT included.
Fitment
Designed as a performance carburetor upgrade for:
Yamaha Banshee YFZ350 – 1987–2006
Because these are larger performance carburetors, appropriate 34mm-compatible intake boots/manifold and throttle cable may be required depending on your existing setup.
Important Tuning Information
These carburetors are supplied with a custom tuned starting baseline, but final jetting should always be verified for your specific engine.
Displacement, porting, compression, exhaust, reeds, intake, air filters, fuel, temperature and elevation can all affect the required jetting. Spare jets are included to make additional fine tuning easier.
These are aftermarket 34mm PJ-type carburetors and are not represented as OEM carburetors.
