Fitted a pair of these and a K&N filter (both bought from HVC with a new Y-pipe manifold and a pair of new carbs rejetted specifically for the filter and the chambers) which turned my '73 RD 250 from a peppy little fun bike into a raging stormer! It sounds authoritative all the time and when it comes on the pipes, it lifts the front wheel and gets gone like never before in a rush of sound, smoke and acceleration. It idles fine, doesn't seem to be finicky or hard to manage at regular speeds, and it's almost frightening what's on tap if you throttle it all the way up. Remarkable! A few issues were handled quickly and politely with phone calls to HVC. First rate all round!
