    Fix the lean

    Everything I've read about and experienced with TTR125's is that they come quite lean from the factory. Replaced the stock 15 pilot jet on my carb with this 17.5 jet to get her running a smidge richer. Installation was super easy and she starts up better when cold. Very happy with the results.

  • Cobra Jet Kit

    Cobra Jet Kit

    Tyson in UT

    WOTH EVERY PENNY!

    I bought this jet kit after installing the cobra boulevard exhaust. All i was looking for was to stop the exhaust backfire when I let off the gas. Being in utah the stock jetting is lean and putting on the pipes makes it worse. I had Steadmans in Tooele install the kit because i wasnt too excited to drill out the mixture plug. It cost me 2 hours labor but worth every cent. No more backfire, no more using the choke on summer mornings, im getting 42 mpg, and up against my buddys roadstar 1700 he can no longer kick my butt in a drag. The 1100 out performs his 1700 not by much but enough that he cant pass or keep up. This is a pretty cheap mod that will certainly boost your performance!

    Higher altitude jet for 2010, 2011 Arctic Cat 90

    I live at 6400 feet, and bought this #78 jet to replace the stock #80 main jet in my kids' 2010 and 2011 Arctic Cat 90 ATVs. It fit perfectly and the ATVs are running great.
