Howdy all. (That's the former Texan talking). Just picked up a 1975 CB550F (I think F?) on Craigslist a few months ago. This site has already been a huge help in rebuilding carbs, tracking down oil light issue (replaced sender, all good), replacing mystery oil with Rotella, and fixing a cracked overflow tube on carb #4. So, thank you! Look forward to learning more and hopefully posting something of my own soon. -Scott
