Hello. Im trying to set up my kids sleds for snocross. one is a 2005 zr120 with the Suzuki engine, the other is a 2011 snopro 120 with the Yamaha engine. I removed the foam from the air cleaner, removed the governor gear, adjustable main jet, aftermarket chain tensioner, and clipped every window.
I was wondering what pilot jet to start with for both of these sleds. I appreciate all the help.
