S 3 Head Sherco 290 2012

Featured Replies

Has anyone fitted a S3 head and low compression insert to a 2012 290 , and what difference did it make to the fueling , mine seems too rich and bogging down. Any comments would be appreciated.

Hi

S3 Head works fine, all i did was change the Pilot jet from 48= 45, main jet down 1 size, was a bit rich when fitted the head now its great :)
