Our billet Yamaha AIS block off plate will fit the 2020+ Rmax and Wolverine 1000cc engines. Helps engine idle better and reduce popping on decelleration. Includes the rubber cap to block off the air valve. Uses your stock hardware and stock spring clamp.

Our stainless steel Yamaha primary clutch washers will fit your 2020+ Rmax and Wolverine 850 and 1000 clutches. Our set includes 3 washers, 0.5mm x 2 and 1mm x 1.  Use these to slightly widen your clutch sheave and allow the belt to ride lower on the sheave, increasing low end torque multiplication. A must for oversized tires. We personally have all 3 shims(2mm) on our Wolverine 1000 and the it drastically brought back the low end we lost with the 30" tires.
