About to tackle my carburetor jetting. Had a question. The JD Jetting kit says to use the 170 main jet. Indy on the WR450 site says to use the 165 jet. I have already done the throttle stop change and removed the AIS stuff. Also have installed the FMF slip on exhaust. I am in Louisiana so low altitude and warm temperatures.
My plan is to install the 170 168 or 165 main jet, 48 pilot jet and Red Needle in position 4. I am leaving the stock leak jet because unable to get by the weekend. Also installing the easily adjustable fuel screw.
Need help on the main jet and any other suggestions you might have.
