YAMAHA DETENTE SPRING SHIFT KIT YZF1000 1997-2001
Includes Heavy duty detent spring and gasket. Makes shifting more positive at the expense of slightly stiffer shift lever action. The stronger detent spring rotates the shift drum quicker, so the gears are more likely to engage under quick shift conditions. Especially helpful in decreasing the 2nd gear and shift fork wear that the FZR1000’s are known for.
