The asv lever i,ve been sent has the right part no on the box, underneath the actual lever its got BR10 F ? stamped on it, my guess is def wrong lever in the right box, the yam bush for the bolt to pass through on the lever is the correct thickness for the perch but the lever is 5mm to thick. it always happens to me! i,ll get hold of the dealer and get it sorted. its a honda cbr asv brake lever in a yamaha fjr box.
