Features & Benefits:-

* Designed with a tighter tolerance on the ID for better fit on the pinion shaft

* Helps to eliminate the timing variance (up to 4 degrees) that is associated with the loose fitting factory sprockets.

* Replaces OEM # 25673-06

Tech Tips:-

* Due to variations in pinion shafts, Fueling have gone a little smaller on the I.D. Using a soft mallet to install is pretty common, after the first install and removal of the sprocket after checking sprocket alignment the 1091 will go on cleaner for final assembly as the sprocket is now somewhat matched to the crank.

* You may want to install these sprockets with the etched ‘Feuling’ name and part number inward as it will start and install slightly easier.
