178 main and 50 pilot is stock jetting which is slightly rich but but keeps the bike running cool and preserves the cylinder. The leaner jetting will run more crisp and be more responsive but also will generate more heat and wear the cylinder just a little sooner. Also you’ll likely be too lean this winter and will need to go back to a richer jetting but it’ll run great this summer. Enjoy! Also get a JIS screwdriver for the carb screws and avoid a normal Phillips to keep from chewing them up.
@@jmarcinko1139 yes the kit comes with a lot of different jets and a chart for your elevation and temperature!yes sir probably get this kit for my 125 too! what is a JIS screwdriver?
