i have one but i ran it only for a weekend. i loved the sound- especialy the top end sound. it looks identacle to my shearer but the shearer is a little bigger/ fatter. for a stock engine there is an advantage for the psi i believe. i have not tried the shearer yet as im doing a frame up restoration.

i didnt know they were similiar till it arrived. i had a chance to get a chhromed shearer and i took it.
