 TT-R125 Jet Kit Installation Notes

(See available PDF for printable version)

Parts Supplied

  • 17.5 & 20 Pilot Jets and 110 & 112.5 Main Jets

Installation Instructions

  • If your TT-R is stock, start with a 17.5 Pilot Jet and a 110 Main Jet.
  • If you have an aftermarket pipe, begin with a 17.5 Pilot Jet and a 110 Main Jet.
  • If you have an aftermarket Air Filter and Pipe, install the 17.5 Pilot Jet and a 112.5 Main Jet.
  • Adjust the Fuel Mixture Screw for the best idle.
  • Should you desire a richer low end, use the 20 Pilot Jet. For a richer mid-range, move the Needle Clip to the 3rd position (from the top).
  • The above recommendations are a good starting point for jetting only. Use the jet combination that makes your bike run the best!
