Output Shaft Spline Wear.
Hi.
This wear only gets really bad when poor quality pattern sprockets are used.
If genuine Yamaha or Renthal sprockets are used - wear is minimal.
JT, who usually make very good pattern sprockets, do not cut the splines correctly on their 575 sprocket.
There is also another pattern that people use (similar to the 575) which doesn't have the extra width shoulder on the back of the sprocket. It is very narrow & promotes fast spline thrust face wear.
The later multi-spline output shafts with non-floating sprockets are better & I supply these shafts for both the early kick only models & the 1VJ.
