Was wondering if there is any sort of break-in period for my Yosh RS-5 slip on. I installed it this past winter, and have only put about 150 miles on since the install. Should I be keeping the RPM's down for x-number of miles, or can I rip it without fear of damage to the motor?

 

I didn't do anything special when I installed my Yoshi Slip-On, 7k miles ago. No break in period,
didn't even have to rejet, though my bike runs a litttttle lean, it might be in my future to rejet
but for now, my bike is all stock.

I think you'll be alright riding the bike the way it was meant to be ridden.... Hard !

 

If your bike is brand new then be easy on it til atleast 500 miles, thats when i started spinning mine to the limiter as far as the Yoshimura goes let er rip.
