Yamaha TTR 125 - Carb Jet Kit | Air Box Modification Kit
To get the most power and best overall performance increase out of your Yamaha TTR-125, we have developed this air box modification and jetting kit.
Jet Kit includes: 2 main jets, 2 pilot jets, instructions and templates for cutting out sections of the stock airbox, and installing the round airbox vent kit.
The easiest performance gain is to improve breathing in the air box. Filtered Air Box Vents are the simplest way to accomplish this. Simply follow the templates with a 1" hole saw and snap-in these vents!
- 1" diameter foam filtered air vents that increase the pre-filtered air supply to the airbox
- May be cleaned and re-oiled
- 2" thick foam square insert
A MUST have for any TTR-125 with an aftermarket exhaust system installed. Also eliminates hard cold starting and idling problems!
More air and more fuel means more power!
*Fits ALL years Yamaha TTR125's and TTR125LE's
