Stage6 High-Flow Fuel Valve – 34 mm Adapter

When you fit a carburettor bigger than stock, the standard fuel valve can't keep up: at full throttle the engine runs lean and risks seizing. This Stage6 high-flow fuel valve guarantees enough fuel supply whatever the conditions, and fits directly on many machines (Beta, Sherco, Fantic, Vent, MBK Booster, HM, MRT, Yamaha DT), with or without an adapter depending on the model.

The 2-hole adapter (34 mm hole spacing) allows fitting on models that need it.

The pack includes:

• Stage6 fuel valve alone
• Or fuel valve + 2-hole adapter

Compatibility with adapter:

• Beta, all years
• Sherco, all years
• Fantic, all years
• Vent, all years
• MBK Booster, before 2004
• HM, all years

Compatibility without adapter:

• MRT
• Booster Stunt / Nitro, after 2004
• Yamaha DT

Benefits:

• ⛽ Enough flow even at full throttle with a big carburettor
• 🛡️ Engine protection against lean running and seizing
• 🔧 Direct fit, with or without adapter depending on the model
• 📈 Suits the most demanding tuning setups

Note: the 2-hole adapter's hole spacing is 34 mm, check compatibility with your model before ordering. Fitting with gasket sealant strongly recommended. Without selecting the option, only the adapter is supplied.
