NOS exhaust flange for the 76 Starfire Liquid Kit 250 & 340. These will also fit the bolt pattern on TXL and many others. They are almost exactly the same as the 72 Starfire 650 & 795. The 72 has the spring loop on the bottom, where these are on top. Could easily be converted. Bolt pattern is 2 3/4" on center and the pipe is 1 3/4" OD.
