Hey Everyone. New to the forum, and new to motorcycles. Picked up a 1980 KZ550 C1 LTD with 18,500 miles April 2018. Rode it for the season and now that it's winter I am going over the bike. New tires, sprockets, chain, brakes, etc.. The only cosmetic thing i would like to change on the bike are the mufflers. I would like something more cylindrical instead of the cone shape. After reading multiple posts I know that changing out the exhaust on the bike will increase flow. Which means I would have to re-jet the carbs to accommodate. Which I have never done before. And I realize it may be easy, but looking at doing anything with the carbs except cleaning. I don't want to mess with the point of no return drilling that could come with the re-jetting.
My questions are:
1) Does anyone make an OEM spec muffler that I can use with my existing headers? (same back pressure to avoid re-jetting)
OR
2) Must the whole header and muffler unit be replaced to get the desired look?
AND
3) If the whole exhaust system does need to be replaced for the desired look:
Are there aftermarket systems that wouldn't require re-jetting?
I already have $400 into it this winter. So I'm am trying to avoid (at least for now) spending another $300 to $500 on a whole new exhaust system. The exhaust I have is in working order. So I am fine with leaving it for now if re-jetting is the only option.
I appreciate any info you can send my way. And I look forward to learning more about my KZ.
