Description
Tighten up crankcase volume and boost reed performance on your Yamaha 62T 701/760 with R&D Crankcase Stuffers. These precision-molded, high-temp plastic inserts reduce dead air space around the reed valve, increasing pressure and vacuum for sharper throttle response, more torque, and stronger power across the entire RPM range.
Performance Boost Explained
- Reduces crankcase volume for higher air velocity and pressure
- Increases vacuum over reeds for quicker opening and better cylinder filling
- Delivers stronger low-end torque and crisper response at any RPM
- Direct slip-in fit for 62T OEM reed cages only
Stock 701/760 crankcases have excess volume that dulls reed efficiency. These stuffers optimize it, making the engine feel more responsive and alive – especially noticeable in hole shots, mid-range pull, and freestyle maneuvers.
High-Temp Durability
R&D uses heat-resistant plastic that withstands crankcase temps and oil/fuel exposure without warping or breaking down over time.
- Improves overall engine breathing and power delivery
- Simple install – no tools or mods required
- Great complement to reed upgrades or pipe kits
- Proven on stand-up racing and freestyle setups
Unlock hidden snap and torque your 701/760 deserves.
Fitment & Install Tips
Access crankcase, clean area, slip stuffers in around reeds. Confirm 62T cage compatibility (not 61X). Inspect reeds during install. Pair with high-flow reeds for max gains.
