WISECO Clutch Basket for YAMAHA WRF 400, YZF 400 1998-2000

On YAMAHA WRF 400, YZF 400 from 1998 to 2000, the WISECO WWPP3018 clutch basket fits in place of the original part. Every time the clutch bites, the plate tabs hammer against the basket slots. A notched basket stops the plates from sliding freely: the clutch becomes snatchy and hard to modulate.
