Boyesen 538 Yamaha 700 V-Max XT1998-1998 Boyesen Reed Yamaha

REVOLUTIONARY PERFORMANCE Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. More valves equals more power by creating: More Air Flow. The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently. More Air Velocity. The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports. More Overall Power. Dual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband. Quicker acceleration for that all-important holeshot. Crisper throttle response for fast corner exits and surer jumps. More horsepower throughout the powerband for guaranteed performance. Improved engine efficiency and fuel economy for the long distance rider. Longer life - Boyesen Power Reeds outlast all other aftermarket reeds. Snowmobile>Fuel and Intake>Reeds>Boyesen Power Reeds.

Laboratory flow analysis proves Boyesen dual-stage reeds outperform standard reeds They permit greater flow velocity over the entire range of operating pressures Increased performance from start-up to top acceleration Fitment 2000-2002 Yamaha Mountain Max 600 MM600 1997-2003 Yamaha Mountain Max 700 MM700 2004-2006 Yamaha SX Venom SXV60 2000-2003 Yamaha SX600R 2000-2001 Yamaha SX700R 1999-2003 Yamaha Venture 600 VT600 1998-2003 Yamaha Venture 700 VT700 1999 Yamaha VMAX 600 VX600 1997-1999 Yamaha VMAX 700 SX VX700SX 1999-2001 Yamaha VMAX 700 VX700DX Deluxe 1998 Yamaha VMAX 700 XT VX700XT
