Exhaust question

Discussion in 'Technical and Troubleshooting Torque' started by Riderman, Apr 15, 2010.

  1. With a carby bike, if you were to simply put a slip-on exhaust on, is a rejet mandatory? Does anything else need to be done or is it just slip-on and play?

    I've heard people say you need to rejet, and others say it's fine (only rejet if its a full exhaust).
  2. If you aren't changing the air in side of things, you shouldn't have to rejet with a slip on imo.
  3. I wondering if it will cause the bike to run richer?
  4. It depends on which bike, which pipe, where you are... It can vary depending on trhottle position as well

    With my bike, slip ons made it run slightly richer down low.

    If you're unsure, get it tuned after.
  5. Agree with MV, it depends on the bike, the exhaust, altitude etc.

    What bike do you have and what exhaust are you looking at ? You could try asking the exhaust manufacturer, or jumping on a forum for your bike type and asking there.
